					                    FIRE PROTECTION MANUAL

                                PREFACE

The First Edition of this Manual was issued by the Calcutta Fire Insurance
Association in 1906 and was brought up-to-date and re-issued in 1930. The
third, fourth and fifth Editions were published jointly by the Insurance
Associations of India and Pakistan in 1948, 1950 and 1953 respectively to
provide for the needs of the whole of the areas controlled by these
Associations. The subsequent sixth, seventh and eighth Editions were
published by the Fire Sectional Committees of Calcutta, Bombay, Delhi and
Madras Regional Councils of the Insurance Associations of India. In the
ninth Edition published in 1982, amendments and additions were effected to
bring the provisions in line with current thinking on fire protection
techniques and to encourage installation of fixed fire extinguishing
appliances/alarm systems in relatively low hazard risks on the one hand and
tighten requirements for design of systems suitable for high hazard risks
such as Petroleum Refineries, Petrochemical and Fertiliser Plants on the
other hand, which, world-wide experience has indicated, need copious
quantities of water and other extinguishing media. In this tenth Edition an
effort has been made to further update and streamline the regulations.

The Manual should prove of value to factory owners and their technical
personnel when dealing with matters relating to fire extinguishing
appliances and also constitute a handy book of reference to Insurance
officials.

The maintenance of fire extinguishing appliances in an efficient state and
familiarisation with all details of operations is essential if the maximum
benefit is to be derived in the emergency of an outbreak of a fire.

The Manual incorporates long experience of fire protection engineering
both in India and elsewhere in the world. Compliance of the rules will not
only obtain appropriate discount in the fire insurance premium but will also
instil feeling of security that the presence of an efficient fire-fighting
equipment should engender. Direct loss from fire and the resultant wastage
is always serious but the indirect loss and the resultant dislocation of
business is often much more serious.

The Regional Offices of Tariff Adv. Committee maintain an inspection staff
of qualified engineers, specialists in fire protection and prevention
engineering and practice in all its aspects. The services of this staff are
available to make recommendations and carry out inspections in keeping
with the nature of work. (All references to Committee or staff thereof in this
preface and in the body of the Manual apply to the Committee controlling
the territory within which the risk is situated).

The Manual initially deals with portable appliances and small bore hose
reels, which are considered as first-aid appliances. The regulations
regarding trailer pumps are covered next. The last part is devoted to fixed
external protection in the form of a hydrant system which is considered the
backbone of the entire fire-fighting operations as it fights fires of serious
proportions in all classes of risks and continues to do so even in the event of
a collapse of the buildings/structures protected. High-rise buildings which
have become a common feature of modern society present inherent fire
hazard as fire brigades are often helpless in the face of fires in such
structures and are unable to save human lives and fight fires effectively
with traditional methods. A separate section has, therefore, been devoted for
prescribing the specialised type of protection required by these structures.

In case it is desired to install any appliances, which are not covered by this
manual, assistance and advice may be obtained from the inspection staff
maintained by the Regional Offices.

Wherever reference to any Indian Standard appears in this Manual, it
should be taken as a reference to its latest version.

2.2 Discounts will be considered only if all hand appliances and
    their accessories as well as all components of hydrant,
    sprinkler and other fire protection systems are of a type and
    make, approved by the Tariff Advisory Committee.

2.3 No discounts will be considered for a sprinkler or hydrant
    system unless the same has been hydraulically tested with
    trenches open atleast once during the course of installation by
    the Committee's Inspectorate, and found in order. Further, site
    engineer of the Installing Contractor should maintain progress
    record with “protocol” duly signed by representative of the
    client and him.

2.4 The prior submission of proposals to the Committee before
    the work is commenced, is essential, to ensure that the
    installation will conform to the Committee‟s requirements but
    does not dispense with the procedure laid down hereafter for
    application for the sanction of discounts.

2.5 Application for discounts shall be submitted on special forms
    provided for the purpose by the Committee and shall
    comprise:

    2.5.1    Application by the Leading Office (Appendix I)
    2.5.2    Guarantee by the Insured (Appendix II)
    2.5.3    Schedule of Appliances        (Signed    by   Insured)
             (Appendix III)

2.6 In every case, a plan of the premises prepared in accordance
       with the requirements indicated in 1.1 to 1.5 shall
       accompany any application for a discount for fire
       extinguishing appliances and, in the case of sprinkler
       and/or hydrant installations, Installing Engineers‟ detailed
       'As Erected‟ working drawings are essential.

       N.B. A Certificate of Completion from the installing
       Engineers stating the pressure to which the installation(s)
       has been subjected and giving the date(s) from which it was
       in complete working order should also be submitted.
       Further, progress record with protocol duly signed by
       client, installing contractor and/or project consultants
       should be submitted.

2.7 Even in the case of extensions to an existing service, a
      complete set of forms and plants detailed in 2.5 and 2.6
      above shall be submitted.

2.8 Applications, which relate to discounts for appliances other
      than hydrants, shall also be accompanied by a plan of the
      premises showing the layout and distribution of appliances.

2.9 No application for discount can be entertained until the
      relative appliances are complete, in position, ready for use
      and fully operative. An appropriate discount or allowance
      will be sanctioned by the Committee from the date of the
      completed application, (in accordance with 2.5 and 2.6
      above) subject to the appliances being found in order on
      inspection by the Committee‟s Inspectorate. In the event of
      the installation being found incomplete or defective, the
      discount will be with held (or withdrawn if already
      notified) until the detects have been rectified to the
      satisfaction of the Committee.

2.10 No allowance shall be made for Fire Extinguishing
       Appliances until notified by the Committee either by letter
       or circular, and then, with effect only from the date
       specified in such notification.

2.11 Discounts sanctioned solely on account of installation of
        internal appliances will be valid for a period of four years
        only; hence fresh applications, accompanied by the report
        of the Engineers of the Insurance Company (as per
        Appendix IV) shall be submitted every four years.
2.12 Proposals for the installation of appliances not specifically
        covered by these rules shall first be submitted to the
        Committee for approval.

2.13 Offices and the insured are requested not to change block
       numbers as this naturally affects the Committee‟s records
       and causes confusion. If block numbers have to be
       changed, the Committee shall be notified at once.

2.14 Discounts sanctioned for installation of appliances shall
        normally stand withdrawn in the event of a strike or
        lockout in the premises for duration of seven days or more.
        For this reason, it is imperative that the Committee be
        apprised as soon as a strike or lockout is declared.




                     ********
3.   COMMITTEE'S INSPECTION STAFF:

     3.1 The Committee undertakes, as far as possible, the periodical
         inspection of all premises in which fire extinguishing appliances,
         entitling the risk to special discounts or ratings for such appliances,
         are installed.

         For this purpose, the Committee‟s Inspection Engineers shall have
         the right of access to the premises of the Insured at any time with
         or without giving any prior notice.

     3.2 The Primary duty of the Inspectors is to report to the Committee on
         the condition and efficiency of the appliances installed as well as
         to ensure the regulations are being observed. They will, however,
         give help and advice in the maintenance of the appliances and on
         matters pertaining to fire protection and prevention.

     3.3 The attention of the Inspecting Engineers shall be drawn, during
         their visits, to any changes effected since the previous inspection
         or to any contemplated extensions and alterations to the existing
         services. This procedure does not, however, dispense with the
         necessity of advising the Insurance Company or Companies
         interested on the risk of any changes, which affect the plan of the
         risk or the details of the appliances, recorded with Committee.




                               ****** ***
4.   INTERNAL APPLIANCES -

4.   Internal appliances generally consist of hand appliances (first aid
     appliances) and hose reels.

     4.1 HAND APPLIANCES -

     4.1.1   GENERAL –

     4.1.1.1   Hand     appliances          comprise        buckets        and
               extinguishers.
     4.1.1.2 ALL APPLIANCES INCLUDING EXTINGUISHER
             REFILLS AND FOAM COMPOUND SHALL BE IN
             CAPACITIES INDICATED IN THE RELEVANT INDIAN
             STANDARDS SPECIFICATION AND SHALL BEAR ISI
             CERTIFICATION MARK.                (Accessories including
             extinguisher refills shall also be ISI marked) BUCKETS
             SHALL BE OF ROUND BOTTOM TYPE.

     4.1.1.3 The usefulness of these appliances is limited, as it is entirely
             dependent upon the presence of persons having knowledge to
             operate them. Everything depends, however, on the speed
             with which they are brought into use as they are essentially
             „First-Aid‟ equipment, only meant for attacking small fires in
             their incipient stages and are not intended to deal with large
             outbreaks of fires.

     4.1.1.4 Since a variety of shapes and/or methods of operation of fire
             extinguishers can at times lead to confusion and as failure to
             operate the extinguishers properly in the first instance results
             in failure to quench the fire, it is recommended that
             extinguishers installed in any one building or single
             occupancy be similar in shape and appearance and have the
             same method of operation as far as possible.

     4.1.1.5 It is recommended that an indicator board showing the
             number of buckets and extinguishers installed in each
             department be provided over or near the main entrance to the
             department. This will enable the person in charge of the
             appliances to ascertain at a glance if any appliances are
             missing.
4.1.1.6 It is advisable to provide conspicuous location indicators of a
        suitable type for all extinguishers, particularly those located in
        large compartments.

4.1.2    SELECTION OF HAND APPLIANCES:

4.1.2.1 Various types of hand appliances are available but all are not
        equally effective on all kinds of fires. For this reason, the
        nature of contents of a building, the processes carried out
        therein and the types of fires, which may occur, shall be taken
        into consideration while selecting fire appliances.

4.1.2.2 The different types of fires and appliances suitable for use on
        them are as under –

          Class           Combustibles              Hand Appliances

                                                 buckets

        N.B - WHERE THE ENERGISED ELECTRICAL
        EQUIPMENTS ARE INVOLVED IN A FIRE, THE NON-
        CONDUCTIVITY OF THE EXTINGUISING MEDIA IS OF
        UTMOST IMPORTANCE AND ONLY EXTINGUISHERS
        EXPELLING DRY POWDER OR CARBON-DI-OXIDE
        (WITHOUT METAL HORN) SHOULD BE USED. ONCE
        THE ELECTRICAL EQUIPMENT IS DE-ENERGISED
        EXTINGUISHERS SUITABLE FOR CLASS A, B AND C,
        MAY BE USED SAFELY.

       Note- Any combination of the various appliances referred to
             above may be employed.

4.1.3.5 For electrical equipments, it would be necessary to provide
        extinguishers as under –

    4.1.3.5.1 For rooms containing electrical transformers,
              switchgears, motors and/or electrical apparatus only, not
              less than two 2 Kg dry powder or carbon dioxide type
              of extinguishers shall be provided within 15 m of the
              apparatus.

    4.1.3.5.2 Where motors and/or other electrical equipments are
              installed in rooms other than those containing such
              equipments only, one 5 Kg dry powder or carbon di
              oxide extinguisher shall be installed within 15 m of
              such equipments in addition to the requirement of rules
              4.1.3.2 and 4.1.3.4 for this purpose, the same
              extinguisher may be deemed to afford protection to all
              apparatus within 15 m thereof.
    4.1.3.5.3 Where electrical motors are installed on platforms, one
              2 Kg dry powder or carbon di oxide extinguisher shall
              be provided on or below each platform.

                In the case of long platform with a number of motors,
                one extinguisher shall be accepted as adequate for every
                three motors on the common platform.

                NB- the above requirement will be in addition to the
                requirements of rules 4.1.3.2 and 4.1.3.4

4.1.3.6 If in the premises, fires of class C and D are also likely to
        occur, the appropriate extinguishers and the number of such
        extinguisher will be decided by the Committee, in view of the
        special nature of occupancies.

4.1.3.7 Under special conditions, wheeled type of extinguishers may
        be installed with the prior approval of the Committee.

4.1.3.8 The appliances shall be so distributed over the entire floor
        area, that a person has to travel not more than 15 m to reach
        the nearest appliance.

        Example - The following example will illustrate the method
        of determining the number of fire extinguishers required to
        give adequate protection for a given property.

        Risk:     Light Engineering Workshop (Light Hazard).
        Area:     315 m x 112 m. i.e. 35,300 sq. m.

        Types of Fires:

        i)        Class `A' fire due to normal combustibles.
        ii)       Class `B' fire due to existence of Spray Painting
              process and storage of flammable liquids.

        Number of appliances:

        i)        Basic Protection -

              353 Buckets and
              59 Water type Extinguishers OR
                90 Water types Extinguishers, if buckets are dispensed
                   with.
         ii)         For Class „B‟ fires 2 Water type Extinguishers are
                replaced by 2 Dry Powder Extinguishers.
         iii)        For electrical equipments 6 Dry Powder Extinguisher
                are provided. Thus the final number of Extinguishers is:
                Water type               88
                Dry Powder type          08
                Total                    96

4.1.4    Selection of Sites for the Installation of Hand Appliances:

4.1.4.1 When selecting sites for hand appliances due consideration
        shall be given to the nature of the risk to be covered.
        Appliances shall be placed in conspicuous position and shall
        be readily accessible for immediate use in all parts of the
        occupancy. It should always be borne in mind while selecting
        sites that hand appliances are intended only for use on
        incipient fires and their value may be negligible if the fire is
        not extinguished or brought under control in the early stages.

4.1.4.2 Generally, hand appliances shall be placed as near as possible
        to exits or staircase landings. Wherever possible, advantage
        shall be taken of normal routes of escape by placing
        appliances in positions where they can readily be seen by
        persons following the natural impulse to get out of danger. It
        is not advisable to place appliances at the end of rooms remote
        from exits unless they are necessary to cover a particular
        hazard there.

4.1.4.3 Buckets shall be placed at convenient and easily accessible
        locations either on hangers or on stands. In the case of textile
        mills, it is strongly advised that a bucket be slung at the end of
        each spinning and roving frame.

4.1.5    Maintenance of Hand Appliances:

4.1.5.1 General

    4.1.5.1.1 It is important that hand appliances are always kept in
              their proper positions and if temporarily removed for
              repairs, are immediately replaced. In order to ensure
              this, all concerns shall arrange to provide at least one
              man, preferably a pump man, whose duty is to see that
              the fire buckets are filled with water and the
              extinguishers are in efficient working order and that all
              appliances are in their correct positions.

    4.1.5.1.2 It is recommended that in case the paint of any hand
              appliance gets chipped off or gets faded; it shall be
              repainted to prevent it from rust and corrosion.

4.1.5.2 Buckets:

    4.1.5.2.1 Fire buckets shall not be used for any purpose other
              than that for which they are intended, and shall always
              be kept full of water/sand.

    4.1.5.2.2 To prevent breeding of mosquitoes and to comply with
              rules of local bodies, the water in fire buckets shall be
              refilled every week and treated with sapon creosote or
              phenyl in suitable quantities to just discolour the water.

    4.1.5.2.3 All buckets shall be refilled with clean water or sand, as
              the case may be, immediately after use.

    4.1.5.2.4 Spare buckets to the extent of 10 % of the total number
              installed on the premises, subject to a maximum of 50,
              shall always be kept in store.

4.1.5.3 Extinguishers:

    4.1.5.3.1 Spare charges to the extent of 10 % of the total number
              of extinguishers installed, with a minimum of two shall
              always be kept in stock for each type of extinguisher
              and be readily available.

    4.1.5.3.2 Once a week, the extinguisher shall be checked to
              ensure that all movable parts are working properly, that
              the plunger is in fully extended position, that the nozzle
              is not obstructed in any way and that there is no leakage
              of the extinguishing medium from the glands and
              nozzles.      The extinguishers shall be cleaned
              superficially and the brass parts polished. The nozzle
          outlet and vent holes in the threaded portion of the cap
          shall be checked for clogging.

4.1.5.3.3 Once a month, extinguishers of the Carbon Dioxide
          type shall be weighed. If the weight recorded for any
          extinguisher is less than 90 % of the weight of the fully
          charged extinguisher as marked on the body, the
          extinguisher shall be sent for recharging.

4.1.5.3.4 Half the total number of water type of extinguishers and
          one-fifth of the total number of Dry Powder
          Extinguishers installed in the premises shall be
          subjected     to    an    operation       test  annually.
          Advantage shall be taken of this test to impart training
          in the use of extinguishers, to the staff employed on the
          premises where the extinguishers are located.

          N.B. Extinguishers, which have been used in a fire
          during a period of six months preceding the tests, need
          not be taken for testing.

4.1.5.3.5 Extinguishers installed in the premises shall be
          subjected to a hydraulic test as specified in IS: 2190 and
          at such intervals as laid down therein. Extinguishers
          found leaking or distorted shall be rejected. Under no
          circumstances shall such extinguishers be welded and
          reused.

          N.B. The hydraulic test shall be certified by the
          manufacturer(s) of the appliance(s) or the factory Chief
          Engineer or the Factory Fire OR SAFETY OFFICER or
          the service contractors.

4.1.5.3.6 A record of the operation and hydraulic tests shall be
          maintained, which shall be open to examination by the
          Committee‟s inspection staff.

4.1.5.3.7 The operating instructions of the extinguishers shall not
          be defaced or obliterated. In case the operating
          instructions are obliterated or have become illegible due
          to passage of time, fresh transfers of the same shall be
          obtained from the manufacturers of the appliances and
          affixed to the extinguishers.
4.2 Small Bore Hose Reels:

    (This sort of protection is not deemed suitable for
    buildings/compartments containing electrical apparatus only or in
    respect of buildings/ compartments in which flammable liquids are
    stored and/or used)

4.2.1   HOSE REELS SHALL NORMALLY BE CONNECTED TO
        THE GENERAL WATER SUPPLY PIPELINES OF THE
        PLANT/PREMISES.

4.2.2   The number and distribution of hose reels shall be such that
        the whole of each floor is protected and that no part of the
        floor is more than 6 m. distant from a hose nozzle when the
        hose is fully extended.

4.2.3   The hose reel shall be such as will enable not less than 22.5
        litres of water to be discharged per minute through a nozzle of
        not more than 6.35 mm. internal diameter.

4.2.4   Hose shall be of reinforced rubber not less than 19 mm. and
        not more than 32 mm. internal diameter.

6.   HYDRANT PROTECTION OF HIGH RISE BUILDINGS (NON-
     INDUSTRIAL)

     6.1 Introduction -

     6.1.1 A building, the highest floor of which is more than 22 M above
           the surrounding pavement level, shall be considered as a high-
           rise building.

     6.1.2 The rules are applicable to all types of buildings with non-
           industrial occupancies such as Residential Hotels, Mercantile/
           Business/Office buildings, apartments etc.

     6.1.3 In case of Buildings situated in slopping terrain, reference shall
           be made to the Committee in advance with full particulars.

     6.2 Hydrant Protection (at ground or yard levels) -

     6.2.1 The ground level protection with hydrants on terminal mains will
           be acceptable, provided the plinth area of the building to be
           protected is less than 750 m2. The location of the hydrants at
           ground level as well as the layout of the hydrants system shall,
           otherwise, comply with various provisions under Section 7 of
           this manual.

     6.2.2 In case of buildings having a plinth area in excess of 750 m 2, the
           location of the hydrants at ground level as well as the layout of
           the hydrant system shall be governed by the appropriate
           provisions under Section 7.6 of this manual. The Committee
           reserves its right of insisting on water monitors in place of few
           hydrants if deemed necessary.

     6.2.3 Orifice plates of suitable design shall be provided in the landing
           valves, where necessary, to limit the operating pressures within 7
           kg/cm2.

     6.2.4 Except where impracticable, all hydrant outlets shall be situated
           1.0 m above ground level.

     6.3 Hydrant Protection - at various upper/lower (basement) levels

     6.3.1 Access staircase
6.3.1.1 Design for a new building shall include provisions for adequate
        access staircases and lifts to provide efficient means of escape
        and facilities for fire fighting.

6.3.1.2 One lobby approach staircase along with fire lift shall be
        provided for every 1,000 m2 of floor area of each storey/level
        (including basements). Normally a minimum of two such
        staircases shall be required but in case the area of each storey is
        less than 500 m2, one staircase is acceptable.

6.3.1.3 The lobby approach staircase shall be of non-combustible
        construction. At least 50 % of total numbers of staircases
        required (with a minimum of one) shall be so located that one
        of their enclosing walls be an external wall of the building.

6.3.1.4 Doors at the entrances of both the lobby approach access
        staircases and fire lifts shall be provided with self-closing,
        smoke-tight doors having one-hour fire resistance. This
        arrangement will enable escape and fire fighting to be effected
        more efficiently.

        NOTE: If the staircases and the fire lifts are located in the core
        of the building, a positive pressure of 50 Pa or 20 Pa in excess
        of pressure in the lobby whichever is higher, shall be
        maintained within the former as an alternative to the above
        provision.

6.3.1.5 The fire lifts shall be controlled by the fire brigade recall from
        the concourse level and shall not respond to other calls after the
        fire brigade key has been activated. The cable supplying power
        to the lift motor shall pass through routes of negligible fire risk.

6.3.2 Wet Risers -

6.3.2.1 Wet riser(s) is/are a pipe or a number of pipes, permanently
        charged with water under pressure, rising through the full
        height of the building.

6.3.2.2 The wet risers shall be located within the lobby approach
        staircases.

6.3.2.3 The diameter of the riser pipes shall not be less than 150 mm
        anywhere. One or two landing valves shall be connected to the
        riser pipe at each storey/level. In case of excessive pressures in
        hydrant outlets at lower levels, orifice plates of suitable design
        shall be provided in the landing valves, where necessary, to
        limit the operating pressure to 7 kg/cm2.

6.4 Hose Pipes and Nozzles

6.4.1 Sufficient length of hose, subject to a minimum of two lengths of
      15 M each with couplings attached, shall be provided for use in
      case of each hydrant point on risers. In addition, one nozzle of
      20 mm size fitted to a branch pipe shall also be provided. To
      avoid water damage, it is advisable to have reinforced rubber-
      lined hoses for use with internal hydrants. (IS-636)

6.4.2 The number of hose pipes provided near external yard hydrants
      shall be such that no part of the floor is more than 15 M from a
      hose nozzle when the hose is fully extended and connected to
      hydrant landing valve.

6.4.3 Hoses, nozzles and branch pipes shall be kept adjacent to the
      hydrant outlet, in wall boxes or recesses in the walls specially
      designed to blend architecturally with the buildings, if so desired.
      All other requirements relating to the appurtenances shall be as
      per the provisions under Section 7.7 of this Manual.

6.5 Pumping Arrangements

6.5.1 Each wet hydrant installation shall be supplied with water by an
      auto-start pumping set. A stand-by pump set of identical
      pumping capacity having a different prime mover shall also be
      provided.

6.5.2 Pumps shall have capacities of 38 Litres. per seconds (137 m3
      per hour) or 47 Litres. per second (171 m3 per hour) and the head
      generated at the rated discharge shall be such that a minimum
      pressure of 3.5 Kg/cm2 will be available at the highest landing
      valve in the premises.

6.5.3 The suction, delivery and priming arrangements for the pump
      shall comply with provision under Section 7.4.1 of this Manual.

6.5.4 Jockey pump(s) shall be installed in addition to the main pump
      set(s). The pressure setting for the pump(s) shall be such that it
      cuts in approximately at 0.35 Kg/cm2 below the normal system
      pressure and cut out at normal system pressure. The main fire
      pump(s) shall be arranged to cut in approximately at 1 Kg/cm 2
      below the normal system pressure and shall be capable only of
      manual shut down at churn pressure.

6.5.5 The power supply to the fire pump(s) shall be independent of all
      other supplies within the premises. In other words even when
      the power supply to the entire premises is switched off, the
      supply to the fire pump(s) and other essential equipment shall
      remain uninterrupted.

6.5.6 Pump room shall be normally located detached in the compound
      of the building and shall preferably be 6 m away from the
      building. Where it is not feasible the pump room can be located
      inside the building provided it is segregated from the remainder
      of the building in accordance with Committee‟s regulations and
      access to the pump room from the out side of the building shall
      be either direct or through a passage which has no openings other
      than to the pump room.

6.5.7 The pumping installation for the high rise installations shall
      conform to anyone of the following methods to avoid
      undesirably high pressures in the riser mains -

      a)   Two pumps, one having a low head connected to the riser
           feeding the lower storeys and the other having a higher head
           connected to the risers feeding the upper storeys, shall be
           installed.
      b) A multistage multi-outlet pump shall be installed, separate
         outlets being connected to the riser feeding the lower storeys
         and those feeding the upper floors. (See figure 1 and 2)

      N.B. - For buildings over 60 M in height, hydrant system may
      either be designed as above or may be divided into pressure
      zones. For each zone the water supply for the fire protection
      would be designed to have pressure within the normal operating
      ranges and zones of eight to ten storeys would be adequate with a
      check valve in each zone to prevent the transmission of pressure
      to the zone below (each zone shall have a height of 20 m to 25 m)
      In each zone of fire protection piping, there shall be a gravity or
      pressure tank supply. This shall be supplemented by a fire pump
      to provide required flow in the zone. The fire pump shall not be
      used to fill gravity or pressure tank.
      This should be filled from domestic water lines. In this
      arrangement, the pump in the lowest zone takes suction from
      suction tank located at ground floor whereas pumps in other
      zones take suction from the gravity/pressure tanks in the
      respective zone (See. Fig. 3)
      N.B.1: - In addition to the above system, a gravity tank of 25,000
      litres capacity shall be provided on the top of the building and it
      shall be connected to the pump delivery through a non-return
      valve.
      N.B.2 - The pump controls can be located with the pump in each
      zone. It can also be provided at the ground floor depending upon
      the suitability and practicability of the particular building in
      question.
6.6 Water Source -
6.6.1 Effective capacity of fire fighting tank (See rule No. 7.3) shall
      not be less than 2 hrs. aggregate pumping capacity for buildings
      less than 60 m in height. The tank capacity shall, however, be
      increased to 3 hrs. pumping capacity for buildings having height
      60 m and above. The tanks shall be constructed in two
      independent but interconnected compartments as per rule 7.3 of
      this Manual.
      The fire tank must be in two compartments with a baffle wall in
      between not going right down to the base of the tank. This
      arrangement will ensure proper circulation of the firewater and
      prevent stagnation. (See figure below).




6.6.2 The storage tank shall be provided with a 150 mm fire brigade
      pumping connection to discharge at least 2,275 Litres per minute
      into the tank. This connection shall not be taken directly into the
      side of the storage tank, but arranged to discharge not less than
      150 mm above the overflow level of the tank. The connection
      shall be fitted with stop valve in a position approved by the
      committee in advance. An overflow connection discharging to a
      visible drain point shall be provided from the storage tank.




6.6.3 The fire brigade connection shall be fitted with four numbers of
      63 mm instantaneous inlets in a glass fronted wall box at a
      suitable position at street level, so located as to make the inlets
      accessible from outside of the building. The size of the wall box
      shall be adequate to allow hose to be connected to the inlets,
      even if the door cannot be opened and the glass has to be broken.
      Each box shall have fall of 25 mm towards the front at its base
      and shall be glazed with wired glass with "FIRE BRIGADE
      INLET" painted on the inner face of the glass in 50 mm size
      block letters.

6.6.4 In addition to the emergency fire brigade connection to the
      storage tank, a 150 mm connection shall be taken from the four
      63 mm instantaneous inlets direct to each hydrant riser so that
      the fire brigade may pump to the hydrants in the event of hydrant
      pumps being out of the commission. The connection direct to
      each riser shall be fitted with a sluice and reflux valve each.

6.7 Fire Fighting Staff

6.7.1 A fire fighting squad consisting of security and maintenance
      personnel under the command of a trained fire chief, conversant
      with the fire control system of the premises, shall be available.
      Further, the public fire brigade shall also be acquainted with
      what is being installed in the premises and how the protection
      systems operate. For this purpose, details of the arrangements
      for fire fighting systems and the layout plan incorporating the
      position of the existing fire protection system shall be forwarded
      to the local fire brigade for their information and necessary
      action.

6.7.2 As the efficiency of the wet riser system depends on the manner
      and speed at which they are brought into use, a squad consisting
      of trained personnel and fire pimp man shall be maintained on
      the premises round the clock. The number of personnel for the
      squad shall necessarily depend upon the size of the building but
      in no case shall be less than four trained persons (excluding
      officer in charge on duty and pump man) be available at anytime
      during the day or night.

6.7.3 A public address system shall be provided on each floor
      including the control room in order to enable security and fire
      fighting staff to give evacuation instructions to the occupants in
      case of fire. Evacuation drills shall be arranged periodically.

6.7.4 A metal strip of 25 mm x 3 mm section shall be provided in the
      staircase enclosure running throughout the height of the building
      to facilitate transmission and reception of fire messages through
      walkie-talkie sets used by brigade personnel. The strip shall be
      electrically insulated from the ground.

6.7.5 A plan of the risk giving floor-wise details of all fire
      extinguishing appliances and water supplied shall be displayed in
      the pump house as well as in the room of the security/fire officer
      who is in charge of the appliances.



                     **************
7.   HYDRANT SERVICE -

     Installation of Hand Appliances as per the Committee‟s Regulations is
     a prerequisite for any occupancy, other than storage occupancy, to be
     entitled to allowance for this system.

     7.1 GENERAL -

     7.1.0 The following Regulations are not applicable to High-Rise
           Buildings, the highest floor of which is more than 22 m above
           the surrounding ground level or to Cotton Gin and Press
           Factories, for which reference may be made to Sections 6 and 8
           respectively.

     7.1.1 A well designed and well laid hydrant service is the backbone of
           the entire fire fighting equipment as it fights fires of serious
           proportions in all classes of risks and continues to be in full
           operation even if part(s) of affected buildings and/or structures
           have collapsed, and also keeps cool all adjoining properties,
           thereby minimising the exposure hazards.

     7.1.2 The advantages of providing for possible future extensions in any
           scheme of hydrant protection is often overlooked. A
           comparatively small extension with its attendant friction losses
           may overload a main so seriously as to necessitate replacement
           by one of larger size and the small additional initial cost of mains
           of somewhat larger capacity than immediate requirements may
           call for, often leads to ultimate economy.

     7.1.3 All components of the hydrant system shall be of a type and
           make approved by the Tariff Advisory Committee.

     7.1.4 The standards laid down in this Manual represent the
           accumulated experience of many years but even when a hydrant
           service is designed and laid in accordance with these standards,
           its efficiency in fire fighting will ultimately depend upon the
           rapidity with which it is brought into action and the ability with
           which its effort is directed.

     7.1.5 The maintenance of an installation is equally vital and the
           importance of organised wet drills at regular intervals, which
           ensure that each man carries out his allotted duties in the shortest
      possible time cannot be too strongly emphasised. (Please see
      rule 7.10 in this connection).

7.2 CLASSIFICATIONS OF OCCUPANCIES -

7.2.0 As the water supply, pumping capacity and other features of the
      hydrant system depend not only on the size of the risk but also on
      its fire growth and spread potentialities, the risks are to be
      categorised under the following classes for the purpose of
      hydrant system design:

7.3 WATER SUPPLY -

7.3.1 Water for the hydrant services shall be stored in an easily
      accessible surface/underground lined reservoir or above ground
      tanks of steel concrete or masonry. The effective capacity of the
      reservoir above the low water level (defined hereunder), or above
      the top of the pump casing (in case of flooded suction) if the
      same is higher than the low water level, for the various classes of
      occupancies and size of hydrant installations shall be as indicated
      in the table 1.

      NOTES –

      1.   The low water level is a point atleast three times the
           diameter of the suction pipe above the draw-off point. (See
           figs.4, 5 and 6)

      2.   Large natural reservoirs with water capacity exceeding 10
           times the aggregate water requirements of all Fire Pumps
           therefrorm may be left un-lined.

7.3.2 Reservoirs of and over 2,25,000 litres capacity shall be in two
      interconnected equal compartments to facilitates cleaning and
      repairs.

7.3.3 The size of the firewater sump shall be such that the smaller side
      is at least equivalent to six times the diameter of the largest
      suction pipe. The suction pipe (s) shall be located along the
      central longitudinal axis of the sump and the positioning of the
      pipes shall be such that no pipe is within a distance of twice its
      own diameter from another suction pipe or from the wall of the
      sump.
7.3.4 Where the Fire pump(s) draw water from the reservoir under
      suction lift conditions the two compartments shall be connected
      to a common sump through sluice or gate valves. The suction
      arrangement of the Fire pump (s) shall be as indicated in rule
      7.4.1.8, 7.4.1.9, 7.4.1.10 and 7.4.1.12 hereunder.

7.3.5 In case of dual purpose reservoirs catering to fire water and
      general water requirements the general water pumps shall draw
      their supply from a separate sump which shall be connected only
      to the fire water sump, the interconnection being so located that
      the effective quantity (as defined above) of water available in the
      reservoir for fire water requirements below the level of the
      interconnection is atleast equivalent to the quantities indicated in
      Table 1. Incoming mains shall be connected to Firewater
      Compartments and only overflow of firewater compartments
      should go to process.
7.3.6 Where the reservoir provides positive suction for the fire
      pump(s) in terms of the note under rules 7.4.1.11, tapping shall
      be taken from both the compartments and shall be connected
      through sluice valves to a common suction header. The pumps,
      in turn, shall draw their suction from the common header through
      sluice valves. In case of dual purpose reservoirs catering to fire
      water and general water requirements, the tapping for the general
      water pumps shall be taken at a higher level such that the
      capacity of the reservoir between the low water level as defined
      heretofore (or the top of the fire pump casing in case it is higher
      than the low water level) and the general water tapping is at least
      equivalent to the requirements indicated in Table 1.

 4.   High Hazard (B)     Not less than 4 hour's aggregate pumping
                          capacity


NOTES –

1.    The capacity of the reservoir for ordinary and high hazard class
      occupancies may be reduced by the quantum of inflow [of one
      hour in case of ordinary hazard, 90 minutes in case of high hazard
      (A) and two hours in case of high hazard (B) occupancies), from a
      reliable sources (other than town's main) having prior approval of
      the committee, but in no case shall the reservoir capacity be less
      than 70 % of that mentioned above.

2.    In case of light hazard class occupancies the minimum capacity of
      the reservoir shall be increased to 2,25,000 litres if the highest
      floor of the building is more than 15 m above the surrounding
      ground level.

3.    A higher capacity of reservoir than that required as per Table 1
      may be stipulated by the Committee where considered necessary.

7.4 PUMPS:

7.4.1 GENERAL

7.4.1.1 Pumps shall be exclusively used for fire fighting purposes, be
        of a type approved by the Committee, and shall be -

         a) Quadruple acting reciprocating steam pumps Or
         b) Electric Motor or Steam Turbine driven centrifugal pumps
            Or
         c) Compression Ignition Engine driven centrifugal pumps Or
         d) Vertical Turbine Submersible pumps.

7.4.1.2 Pumps shall be direct-coupled, except in the case of engine-
        driven Vertical Turbine Pumps wherein gear drives conforming
        to approval standard of Factory Mutual system or right angled
        gear drive class no. 1338 hall be used.

         Belt-driven pumps shall not be accepted.
7.4.1.3 Parts of pumps like impeller, shaft sleeve, wearing ring etc.
        shall be of non-corrosive metal preferably of brass or bronze or
        stainless steel.

         Where seawater is used or where the quality of water
         necessitates the use of special metals/alloys, the use of such
         metals or alloys shall be insisted.

7.4.1.4 The capacity of the pump(s) would depend on whether or not
        tapping(s) for water spray and/or foam protection for
        tanks/spheres/bullets/plants/other facilities is (are) taken from
        the hydrant service. In case there is no tapping from the hydrant
        service, the capacity of the pump shall be as per rule 7.4.1.4.1
        hereunder. However, where the water demand for water spray
        and/or foam protection as per rules 7.4.1.4.2, 7.4.1.4.3,
        7.4.1.4.4, 7.4.1.4.5 and 7.4.1.4.6 is in excess of that required
        for the hydrant system, the pumping capacity shall be based on
        the higher water demand.

     7.4.1.4.1 The capacity for hydrant service shall be determined by
               the class of occupancy and size of installation as per
               Table 2 hereunder:

  ** This provision will apply only in cases where the hydrant service has
      been hydraulically designed as per NB3 (b) under rule 7.5.10.

  NOTES -

  1.   In case of High Hazard (B) risks where the aggregate pumping
       capacity required in terms of the above Table or of rules 7.4.1.4.2,
       7.4.1.4.4, 7.4.1.4.5 and 7.4.1.4.6 hereunder exceeds 1,640 m3/hr.,
       larger capacity pumps are acceptable provided the capacity of the
       largest pump does not exceed 25 % of the aggregate installed
       pumping capacity is disrupted when any pump is in-operative.

  2.   In case of High Hazard occupancies, the pump delivery pressure
       shall be 7 Kg/cm2 if the highest floor of the risk is at a height
       exceeding 15 m above the surrounding ground level.

  3.   In case of Oil Refineries, Petrochemical complexes or other risks
       where double headed hydrants are used throughout the risk so that
       the total number of hydrants (counting a double headed hydrant as
       two hydrants) is about double the number of hydrants required as per
       the general requirements of this Manual, a double headed hydrant
       may be regarded as a single hydrant only.

7.4.1.4.2      Where storage tanks containing flammable liquids are
            protected by a medium velocity water spray system tapped from
            the hydrant service, the water requirements of the spray system
            shall be calculated for tanks located in a common dyke which
            have the largest aggregate shell surface area at a rate of 10 litres
            /minute/m2 of tank shell surface area except where the system
            has been designed to comply with the provisions contained in
            N.B 4 under rule 7.6.19 (mandatory protection) in which case
            the rate of flow can be reduced to 3 lpm/m2).

            Even in the case of tanks located in separate dykes, the shell
            surface area of all tanks located within a distance of 15 m (or
            the diameter of the larger tank if the same is more than 15m)
            shall be aggregated and the water demand of such cluster of
          tanks shall be calculated at the rate of flow indicated in the
          foregoing paragraph.

          The water requirement of the spray system worked out as above
          shall then be loaded for supplementary hose stream protection
          as under –


          Where the largest tank in, in a dyke, has a
          diameter -

          i)     Upto 10 m                              1,150 LPM
          ii)       More than 10 m and upto 20 m        2,250 LPM
          iii)      Over 20 m                           3,400 LPM


       If the total water requirement for spray protection and hose stream
       protection for storage tanks worked out as above exceeds the
       requirements of the hydrant service as per Table 2, the pumping
       capacity shall be equivalent to the former.

7.4.1.4.3 Where storage tanks are protected by a fixed foam system
          connected to the hydrant service, water requirement for the
          foam system shall be equivalent to that required by the largest
          protected tank at a rate of 5 litres/minute/m2 of liquid surface
          area for fixed roof tanks and 12.2 lpm/m2 of rim seal in case of
          floating roof tanks.

         Other conditions regarding supplementary hose stream
         protection, pumping capacity etc., would remain the same as for
         water spray protection.

7.4.1.4.4 Where spheres/bullets are protected by a medium velocity water
          spray system tapped from pressurised hydrant service, water
          requirements of the spray system shall be determined as under -

         Taking into consideration the configuration of bullets/sphere,
         the one which has the largest number of other bullets/spheres
         within R +15 M of the centre thereof shall be selected. The
         water demand shall then be worked out at the rate of 10
         L/min/M2 of the aggregate shell surface area of the
         bullet/spheres concerned and all bullets/spheres within R + 15
         M of the centre thereof.
            Water application may be reduced to 5 LPM/M 2 where the
            bullets/Spheres coated with approved passive materials
            providing fire resistance of at least 2 hours.

            The water requirement of the spray system worked out as above
            shall then be loaded for supplementary hose stream protection
            as under -


                  Water capacity of Bullets/        Supplementary hose
                        Spheres (m3)             stream protection (LPM)

     1.                 Upto and including 50             1,750
             m3
2.                      Above 50 m3 and upto              2,250
                    3
             150 m
3.                      Above 150 m3                      4,500


          If the total water requirement for spray protection and hose steam
          protection for spheres/bullets worked out as above exceeds the
          requirements of the hydrant service as per Table 2, the pumping
          capacity shall be equivalent to the former.

          Note: For design criteria of medium velocity water spray system
          reference shall be made to committee's rules for water spray
          system.

7.4.1.4.5 Where the plants and other facilities are protected by medium
          velocity water spray systems, tapped from hydrant service,
          water requirement of the spray system shall be determined as
          per Committee's rules for water spray systems. Water
          requirements of the spray systems worked out as above shall
          then be loaded by 4,500 LPM for supplementary hose stream
          protection.

               If the total water requirement for spray protection and hose
               stream protection worked out as above exceeds the
               requirements of the hydrant service as per Table 2, the
               pumping capacity shall be equivalent to the former.
7.4.1.4.6 Where transformers are protected by high velocity water
          spray system tapped from hydrant system, water requirements
          of the spray system shall be determined as per Committee's
          rules for water spray system. Water requirement of the spray
          system worked out as above shall then be loaded by 1,750
          LPM for supplementary hose stream protection.

          If the total water requirement for spray protection and hose
          stream protection worked out as above exceeds the
          requirements of the hydrant service as per Table 2, the
          pumping capacity shall be equivalent to the former.

7.4.1.4.7 Where plants and other facilities are protected by
          sprinkler system tapped from the pressurised hydrant
          service, water requirement of the sprinkler system shall
          be determined as per the Committee’s rules for sprinkler
          system.

          If the total water requirement for sprinkler system
          exceeds the requirement of the hydrant service as per
          Table 2, the pumping capacity shall be equivalent to the
          former.

7.4.1.5   Pumps shall be capable of furnishing not less than 150 % of
          rated capacity at a head of not less than 65 % of the rated
          head. The shut-off head shall not exceed 120 % of rated head
          in the case of horizontal pumps and 140 % in the case of
          vertical turbine type pumps.

7.4.1.6   Each pump shall be provided with a plate giving, in the case
          of centrifugal pumps, the delivery head, capacity and the
          number of revolutions per minute and in the case of
          reciprocating pumps, the diameter of the steam cylinders and
          water plungers and the length of stroke as also the ratios of
          the effective aggregate areas of the suction and the delivery
          valves to the area of the water plungers.

7.4.1.7   In case of electrically driven pumps it is recommended that
          compression ignition engine driven stationary pump of
          similar capacity be installed as a standby and vice versa.
          However, where the hydrant service consists of more than
          one pump, not more than half the total number (total number
          + 1 in case of odd number) of pumps shall have prime
          movers of one type.

          (The above provision is not applicable to systems
          commissioned before 1982).

          Notwithstanding the above, if power to motorised fire pumps
          is obtained from two sources, one of which is a captive
          generating plant located in a block either 6 m away from all
          surrounding buildings, where this is not feasible, segregated
          from adjoining building in a manner indicated in rule 7.4.3.1
          more than half the total number of pumps may be of the
          electrically driven type.

7.4.1.8   Each fire service pump shall be provided with an independent
          suction pipe without any sluice or cut-off valves therein,
          unless the pump is situated below the level of the water
          supply in which case sluice or cut-off valves would be
          essential.

          Where the water supply has fibrous or equally objectionable
          matter in suspension or mud and/or sand liable to cause
          accumulation in the installation, suction pipe(s) shall be
          installed in a jack well fed through a culvert from the main
          water supply. At the supply end of the culvert, a sluice or
          gate valve shall be provided.

          NOTE - The suction pipe shall be connected to the pump inlet
          through an eccentric reducer to avoid air pockets.

7.4.1.9   The diameter of the suction pipe shall be such that the rate of
          flow of water through it does not exceed 90 m. per minute
          when the pump is delivering at its rated discharge. If,
          however, the pump is situated below the level of its water
          supply, the diameter of the suction pipe/header shall be based
          upon a rate of flow not exceeding 120 m. per minute.

7.4.1.10 Where the pump is to operate under suction lift conditions,
         the Net Positive Suction Head (NPSH) available at site shall
         be 0.50 m in excess of the actual value required at 150 % of
         the duty point as per the manufacturer‟s curve of the pump.
          NOTE – For the purpose of the above, NPSH available at site
          shall be computed by deducting the sum of the static lift
          (measured from the „low water level‟, defined in rule 7.3,
          upto the centre line of the pump) and friction loss in the
          suction pipe and fittings from atmospheric pressure.

7.4.1.11 Fire Pumps in High Hazard (B) category occupancies shall be
         provided with positive suction and automatic starting devices
         capable of sequential starting of the pumps. The pumps shall
         be connected to audible alarm such as hooter or a siren
         located in a prominent place outside the pump house. Where
         there is a central fire station in the premises, additional alarm
         point shall also be provided in the fire station.

          The pumping arrangement shall also incorporate Jockey
          Pumps to take care of system losses. The capacity of the
          Jockey Pumps shall neither be more than 5 % of the installed
          pumping capacity nor less than 3 % thereof (with a minimum
          of 10.8 m3/hr.) unless the aggregate installed pumping
          capacity is in excess of 820 m3/hr, in which case the capacity
          of the Jockey Pump (s) shall be not less than 25 m3/hr plus 1
          % of the installed pumping capacity in excess of 820 m3/hr.
          Installation of Jockey Pumps also helps to prevent hydraulic
          surges.

7.4.1.12 In the case of Light, Ordinary and High Hazard (A) category
         occupancies, when the pump is above the level of its water
         supply, there shall be a foot valve and a `priming'
         arrangement, the latter consisting of a tank (having a capacity
         at least three times that of the suction pipe from the pump to
         the foot valve subject to a minimum of 1000 litres) connected
         to the delivery side of the pump by a metal pipe having a
         minimum internal diameter of 100 mm with a stop valve and
         a non return valve therein of the same size.

          A reliable independent filling arrangement and a level
          indicator shall be provided for the priming tank and,
          wherever feasible, a continuous overflow arrangement shall
          be provided in order to ensure that the tank is always full. It
          is recommended that for pumps taking suction from a stored
          water supply, a vortex plate shall be installed at entrance to
          the suction pipe.
          Wherever circumstances permit, the pumps shall preferably
          be fixed below the level of the water supply (positive
          suction). If the pumps are automatic in action, they shall
          necessarily be so fixed. However, if the priming
          arrangements are such as to ensure that the suction pipe shall
          be automatically maintained full of water notwithstanding a
          serious leakage therefrom (the pump being automatically
          brought into action to replenish the priming tank should the
          latter be drawn upon at a greater rate than the rate at which it
          is fed from any other source), positive suction may not be
          insisted. In such cases, the capacity of the priming tank need
          not exceed 450 litres and the diameter of the priming pipe
          need not exceed 50 mm. Jockey Pump(s) of capacity
          indicated in rule 7.4.1.11 shall, nevertheless, be provided in
          systems where the main pumps are automatic in action.

          Where pump(s) are automatic in action they shall be
          connected to audible alarm such as hooter or siren located in
          a prominent place outside the pump house. Where there is a
          central fire station in the premises, additional alarm point
          shall also be provided in the fire station.

          NOTE - For the purpose of rules 7.4.1.8, 7.4.1.9, 7.4.1.11 and
          7.4.1.12 a pump shall be considered as having positive
          suction only if the quantity of water in the reservoir above the
          low water level (see N.B. under rule 7.3) or the top of the
          pump casing, whichever is higher is equivalent to the
          requirements of Table 1.

7.4.1.13 Each pump shall be provided with a non-return valve and a
         sluice valve on the delivery side, the sluice valve being
         installed on the upstream side of the non-return valve. A
         pressure gauge shall also be provided between the pump and
         the non-return valve. The size of the non-return valve and cut
         off (sluice) valve shall not be less than the size of the initial
         delivery pipe and, in no case, less than the delivery outlet of
         the pump. Further, as Butterfly Valves can create
         turbulence adversely affecting the pump performance no
         Butterfly valve shall be installed on the suction side.

7.4.1.14 When the premises are also protected by sprinkler installation
         having elevated tank(s) as one of the main sources of water
         supply, and where the arrangement for filling the tank(s) is
         taken from the hydrant service, the connection shall be taken
         directly from the pump to the top of the tank (through a stop
         valve) and not through the hydrant mains. (See fig. below)




7.4.1.15 Pumps shall not be installed in open. The pump rooms shall
         normally have brick/concrete walls and non-combustible
         roof, with adequate lighting, ventilation and drainage
         arrangements.

         The pump room shall be so located as to be both easily
         accessible and where any falling masonry and the like from
         other buildings occasioned by fire or other cause, cannot
         damage the pump room. Normally, pump rooms shall be
         located 6 m away from all surrounding buildings and
         overhead structures. Where this is not feasible the sides of
         the pump room falling within 6 m of the surrounding
         buildings shall be blank masonry walls of 355 mm thickness
         and the roof of the pump room shall be of RCC. Likewise,
         when the pump room is attached to a building a perfect party
         wall complying with the committee's regulations shall be
         constructed between the pump room and the attached
         building, the roof of the pump room shall be of RCC
         construction at least 100 mm thick and access to the pump
         room shall be from the outside. In no case shall the pump
         from be sited within a building occupied for any other
         purpose.
          N.B. for High Hazard (B) occupancies, in addition to the
          above provisions, the pump room shall be located 30 m clear
          of all equipment where flammable fluids having flash point
          below 65o C are handled and/or stored and 15 m clear of
          pipes/pipe racks (of other than water.). This provision shall,
          however, not apply to systems commissioned before 1982.

7.4.2     STEAM DRIVEN PUMPS -

7.4.2.1   The capacity of steam driven pumps shall be based on the
          economical speed recommended by the makers, and the
          pumps shall be provided with a suitable air vessel, steam and
          water pressure gauges. The working parts of the water ends
          shall be of non-corrosive metal.

7.4.2.2   Pumps shall not be used for boiler feeding or any other
          purpose, except for filling the elevated sprinkler tank(s).

7.4.2.3   There shall be at least two boilers connected to the pump, out
          of whom one shall be under pressure at all times.

7.4.2.4   Steam at a pressure of 4.2 kg/cm2 or more if specified by the
          makers shall be available at the pump at all times.

7.4.2.5   The ratio of the area of the steam cylinders to water cylinders
          shall not be less than 2.5 to 1.

7.4.2.6   A relief valve of adequate size shall be fitted on the delivery
          side of the pump and set at a pressure of not more than 1
          kg/cm2 above the delivery pressure of the pump, and if of
          weight and lever type, the weight, when set, shall be secured
          and locked in that position.

7.4.2.7   The diameter of the suction pipe shall in no case be less than
          that of the pump plungers.

7.4.2.8   The steam pipe to the pump shall not traverse ground not
          under the control of the owner of the installation, nor a public
          roadway.

7.4.3     ELECTRICALLY DRIVEN PUMPS -
7.4.3.1   The sub-station(s) and/or D.G. house(s)-supplying power to
          the fire pump(s) shall be of incombustible construction and
          shall be located at least 6 m away from all surrounding
          buildings. Where this is not feasible, all door and window
          openings of the surrounding buildings within 6 m of the sub-
          station(s) and/or D.G. house(s) shall be protected by single
          fireproof doors and 6 mm thick wired glasses in steel
          framework respectively. Like-wise, roof eaves, if any, of the
          surrounding buildings falling within 6 m of the sub-station(s)
          and/or D.G. house(s) shall be cut and wall raised as a parapet.
          The above provisions shall also apply when the sub-station(s)
          and D.G. house(s) are within 6 m of each other.

          Where the sub-station(s) and/or D.G. house(s) are attached to
          buildings, perfect party walls complying with the
          Committee's regulations shall be constructed to segregate the
          sub-station(s) and/or D.G. house(s) from the attached
          buildings and where the attached building is storeyed, the
          roof of the sub-station(s) and/or D.G. house(s) shall be of
          R.C.C. construction of at least 100 mm thickness.

          Transformer cubicles inside these sub-stations shall be
          separated from H.T. and L.T. cubicles and from each other by
          blank walls of bricks/stone/concrete blocks of 355 mm
          thickness or of R.C.C of 200 mm with door openings, if any
          therein, protected by single fireproof doors complying with
          the Committee's regulations. The sub-station(s) and D.G.
          house(s) shall also be separated from each other as above.




          Transformers installed outdoors, which are supplying power
          to fire Pump(s), shall also be located atleast 6 m away from
          all surrounding buildings (including sub-station(s) and/or
          D.G. house(s). Where this is not feasible all door and window
          openings of the building(s) [including sub-station(s) and/or
          D.G. house(s).] within 6 m of the transformer shall be
          protected by single fireproof doors and 6mm thick wired
          glasses in steel framework respectively. Likewise, roof eaves
          of the building(s) falling within 6 m of the transformer shall
          be cut and wall raised as a parapet. Baffle walls of
          bricks/stone/concrete blocks of 355 mm thickness or of
          R.C.C. of 200 mm thickness shall be constructed between
          two transformers and these walls shall be extended
          horizontally 600 mm beyond the extremities of the
          transformers and vertically 600 mm above the highest point
          of the transformers.

          NOTES –

          1.   Where oil capacity of the individual transformer is larger
               than 5,000 litres separating walls must be provided in
               between the transformers and a clear distance as per the
               following table shall be maintained between the
               transformers and the substation –

                                                          CLEAR
               OIL CAPACITY OF INDIVIDUAL

                       Over 30,000 litres                     15


          2.   For High Hazard (B) occupancies, substation(s)
               supplying power to the fire pump(s) shall, in addition to
               complying with the above provisions, be located 30 m
               clear of all equipment where flammable fluids having
               flash point below 65o C are handled and/or stored.

7.4.3.2   Electric supply feeder (s) to sub-station(s) supplying power
          to fire pump shall as far as possible, consist of armoured
          cables buried underground which shall not pass under any
          building or permanent structures.
          If the feeders are laid inside an underground cable duct/
          gallery, they shall be placed in a corner of the duct/gallery
          and shall be isolated from other cables in the duct/gallery by
          means of fire bricks/sand packing/other suitable passive
          protection of at least ½ an hour fire rating.

          Under extenuating circumstances, where it is not feasible to
          lay the feeders underground, the Committee may permit
          overhead feeders provided they do not fall within a horizontal
          distance of -

          A)     15 m of any process buildings/plant or tanks
                 containing flammable liquids. Or

          B) ) 6 m of any other building or tanks containing non-
               flammable liquids or of storage in open.


          NOTE: in case of high hazard (B) occupancies, all
          substations (except main receiving station in the route of the
          electrical supply to the fire pump (s) which receive power by
          overhead feeders shall be provided with two sets of feeders
          which, apart from conforming with the above distance
          provisions, shall be run along two different routes in such a
          way that failure of more than one route due to a single mishap
          would be only a remote possibility.
7.4.3.3   A direct feeder without any tappings shall be laid from the
          sub-station to the pump house. The feeder shall consist of an
          armoured cable buried underground and shall not pass under
          any building or permanent structure.

          The cable run inside the substation from the breaker upto its
          point of burial or entry into cable duct/gallery shall be
          provided with suitable passive protection of at least ½ an
          hour fire rating.

          If the feeder is laid inside an underground cable duct/gallery,
          it shall be placed in a corner of the duct/gallery and shall be
          isolated from other cables in the duct/gallery by means of fire
          bricks/sand packing/other suitable passive protection of at
          least ½ an hour fire rating.
          Under extenuating circumstances, where it is not feasible to
          lay the feeders underground, the committee may permit
          overhead feeders provided they do not fall within a horizontal
          distance of –

          A)     15 m of any process buildings/plant or tanks
                 containing flammable liquids. Or

          B)     6 m of any other building or tanks containing non-
                 flammable liquids or of storage in open.

          NOTE - In case of High Hazard `B' occupancies if the feeder
          to the fire pump (s) is not buried underground, two sets of
          feeder shall be provided which shall –

          A)     conform to the above distance provisions

          B)     be run along two different routes in such a way that
                 failure of more than one route due to a single mishap
                 would be only a remote possibility.

7.4.3.4   Sufficient spare power shall always be available to drive
          pumping set(s) at all times throughout the year.

7.4.3.5   The electric supply to the pumping set(s) shall be entirely
          independent of all other equipment in the premises i.e. even
          when the power throughout the entire premises is switched
          off, the supply to the pump shall continue to be available un-
          interrupted. This can be achieved by taking the connection
          for the pump(s) from the incoming side of the main L.T
          breaker. However, in cases where two or more transformers
          and/or sources of supply are connected to a common bus bar
          the connection may be taken through the bus bars. (See
          figures below)
7.4.3.6   The fire pump circuit shall be protected at the origin by an
          automatic circuit breaker so set as to permit the motor to be
          overloaded during an emergency to the maximum limit
          permissible by the manufacturers. Further, the under voltage
          release/`no volt‟ coil of the circuit breaker shall be removed.

          N.B - Where cable lengths are long enough to warrant back-
          up protection, the Committee may insist on provision of such
          a protection.

7.4.3.7   It is recommended that telltale lamps, which would
          continuously glow when power is available to the fire
          pump(s) circuit, be provided and fixed in a prominent

        IS: 3589 with welded, threaded or flanged joints, adequately
        supported at regular intervals on masonry or RCC stools or
        pedestals and not on pipe racks.

        The spacing of supports shall be 3.5 m for 80, 100 and 125
        mm dia. pipes, 5m for 150, 200 and 250 mm dia pipes and 7
        m for above 250 mm dia pipes.
         Pipes shall be run at least 6 m away from the face of the
         buildings and open storage areas in case of Light and
         Ordinary Hazard Occupancies and 15 m. in case of High
         Hazard Occupancies.

7.5.4    Mains shall not be laid under buildings. Where, however,
         circumstances necessitate laying of mains under buildings,
         prior permission of the Committee shall be obtained and the
         portion of mains falling under the buildings shall be laid in
         masonry trenches with removable covers and cut-off valves
         shall be provided at points of entry and exit. As far as
         possible, mains shall not be laid under large open storages,
         railroads and roads carrying heavy traffic.

7.5.5    The mains shall not traverse ground that is not under the
         control of the owner of the installation nor under a public
         roadway. The Tariff Advisory Committee may, at their
         discretion, relax this requirement in extenuating
         circumstances.

7.5.6    The system shall be capable of withstanding for two hours a
         pressure equivalent to 150 % of the maximum working
         pressure. While hydro-testing inclusion of cut-off valves in
         the mains to be tested should be avoided.

7.5.7    All boltholes in flanges shall be drilled. The drilling of each
         flange shall be in accordance with the relevant Indian
         Standards.

7.5.8    Flanges shall be faced and have jointing of rubber insertion
         or asbestos compound.

7.5.9    Fittings installed underground shall be of cast iron `heavy'
         grade conforming to IS: 1538 or BS: 1641 whereas those
         installed above ground shall normally be of `Medium' grade
         wrought steel or mild steel conforming to IS: 1239 Part II or
         malleable iron fittings conforming to IS: 1879, parts I to X.

7.5.10   Mains shall be laid in rings (excepting as specified to N.B 4
         below) and their sizes shall be as per Tables 3 & 3A but the
         size of the initial pipe shall not, in any case, be less than the
         internal diameter of the delivery outlet of the pump.

Exceeding 100   See NB – 3 (a) and 3 (b) hereunder
* 80 mm diameter terminal and/or riser mains shall be taken
  as 100 mm diameter mains for this purpose.

NOTES -

1) In calculating the number of hydrants in the system, a
   double headed hydrant shall be counted as two, a fixed
   monitor of 63 mm size having nozzle bore of 32 mm
   shall be counted as three, a fixed monitor of 75 mm size
   having nozzle bore of 38 mm shall be counted as four
   and a fixed monitor of 100 mm size having nozzle bore
   of 45 mm as six hydrant points.

    In case of Oil Refineries, Petrochemical complexes or
    other risks, where double headed hydrants are used
    throughout the system so that the total number of
    hydrants (counting a double headed hydrant as two
    hydrants) is about double the number of hydrants
    required as per the general requirements of this Manual,
    a double headed hydrant may be regarded as a single
    hydrant only.

2) For High Hazard occupancies, the hydrant system shall
   be hydraulically so designed that when half the
   aggregate pumping capacity is being discharged at the
   farthest/hydraulically most remote point and the other
   half in the most vulnerable area enroute, a minimum
   running pressure of 5.25 kg/sq. cm is available at the
   former point and the rate of flow of water does not
   exceed 5 m/second anywhere in the system.

    In case the hydraulically most remote point is the area
    determining the fire pump capacity, the entire aggregate
    pumping capacity shall be considered as being
    discharged at this point at a minimum running pressure
    of 5.25 kg/cm2 and the hydrant system shall be so
    designed that the rate of flow of water does not exceed 5
    m/second anywhere in the system.

    In case the hydraulically most remote point happens to
    be light/ordinary hazardous, pressure requirement at this
    point can be restricted to 3.5 kg/cm2. However pressure
    available at the high hazard area immediately preceding
    the ordinary/light hazard area must be 5.25 kg/sq. cm.

3) For Light and Ordinary Hazard Occupancies having
   more than 55 points, either of the following methods
   may be followed -

    a)   The hydrant service be constituted of single or more
         than one inter-connected hydrant systems, each with
         its individual pump set according to Table 2 and
         water supplies equivalent to the aggregate
         requirements of the number of pump sets installed.

    b) A single hydrant system may be installed provided,
       it is hydraulically designed (where the highest
       hydrant is located more than 20 m above ground
       level, pre calculated systems shall not be accepted)
       as per the parameters indicated in N.B. 2 above,
       except that minimum running pressure shall be 3.5
       kg/sq. cm. Instead of 5.25 kg/sq. cm (minimum
       diameter of the pipe used in the ring mains shall
       however not be less than 100 mm).

4) In the case of riser mains in storeyed buildings and in
   locations where it is not feasible to lay a ring main, a
   terminal main may be provided, but in no case shall the
   number of hydrants on such terminal mains exceed 5.

    A terminal main of 80 mm diameter shall not feed more
    than one hydrant, that having a diameter of 100 mm shall
    not feed more than two hydrants, that having a diameter
    of 125 mm shall not feed more than three hydrants and a
    main of 150 mm shall not feed more than five hydrants.

    The Committee may, at their discretion, permit more
    than five hydrants on riser mains of storeyed structures.

5) In case of systems designed on the basis of pressure loss
   calculations, the piping routes selected along with „nodal
   point‟ commemorating with the pressure loss calculation
   sheets should be distinctly marked in the drawing.
7.5.11   Cut-off (Isolating) valves are necessary to obtain the best
         possible pressure at the seat of fire as they enable a damaged
         portion of the installation to be isolated whilst full pressure is
         available throughout the remainder. These valves are
         distributed according to the general layout of the installation
         and not according to fixed rules. For this reason, the
         proposed position of these valves shall have the prior
         approval of the Committee.

         Cut-off valves shall conform to IS: 780, PN 1.0/IS: 2906,
         Class 2 or AP9600 in case of Cast Steel Valves of class 150.

         NOTES -
         1. In case of system having working pressure in excess of 7
            kg/cm2 PN- 1.6 rating would be necessary for valves
            conforming to IS: 780 and Class 3 for those conforming
            to IS: 2906. Cast Steel valves of class 150 are, however,
            acceptable irrespective of the working pressure of the
            system.

         2.   Other types of valves like rising spindle valves may be
              used, subject to prior approval of the Committee.

         3.   Butterfly valves also can be accepted subject to the
              condition that the valves of diameter exceeding 150 mm
              shall necessary be of gear operated.

7.5.12   All cut-off valves shall be of the right-hand type and
         enclosed in properly constructed surface box, at least 1 m2 so
         as to allow for broken joints being easily remade. The top of
         the surface box shall be 80 mm above ground level, except
         where it is locate on a road. Valve wheels shall have an
         arrowhead engraved or cast thereon showing direction for
         turning `open' and `close'.

7.5.13   It is recommended that the position of the surface box be
         indicated by an iron plate painted `fire red' with distinct
         lettering. Such plates shall also show the `open' and `close'
         direction as cast or indicated on the valves and the serial no.
         of the sluice valve also should be indicated.
7.5.14   In case of installations in earthquake prone zones, some form
         of flexible couplings approved by the Committee shall be
         used for jointing purposes.

7.6      HYDRANTS/FIXED MONITORS:

7.6.1    Water shall be available immediately to all hydrants/fixed
         monitors at all times, with all cut-off valves being kept open.
         Before final inspection the hydrant system shall be flushed
         thoroughly.

7.6.2    Connections for any purpose other than fire fighting are not
         permitted from the hydrant/fixed monitor/stand post or from
         any portion of the hydrant service.

7.6.3    Except where impracticable, all hydrant outlets shall be
         situated 1 m. above ground level.

7.6.4    The stand posts shall be 80 mm in diameter for single headed
         hydrants. 100 mm for double-headed hydrants and monitors
         of 63 mm or 75 mm size and 150 mm for monitor of 100 mm
         size. It is recommended that stand posts be painted `fire red'
         (shade No.536 as per IS:5) and numbered for easy
         identification.

7.6.5    Permission to install hydrants below ground level will be
         given in very special cases only. Where such permission has
         been given, the hydrants shall be properly enclosed in a
         surface box of cast iron or masonry 750 mm square and 80
         mm above ground level, the top of he hydrant outlet being
         not more than 80 mm below the top of the box.

7.6.6    Only oblique hydrants conforming to IS: 5290 of Type A
         with outlets angled towards ground shall be used. The
         hydrant couplings shall be of gun metal/stainless steel of the
         instantaneous spring-lock (female) type of 63 mm diameter
         and valves shall be of the screw down type.

         Branch pipe/nozzle of monitor shall be of gun metal/
         stainless steel.

         N.B - Orifice plates of suitable design may be provided for
         hydrants where the pressure exceeds 7 kg. /cm2.
7.6.7    Double-headed hydrant shall consist of two separate landing
         valves. A single control valve will not be permitted.

7.6.8    Hydrants shall be easily accessible, storage of any kind on or
         around the hydrant being prohibited. Where hydrants are
         situated in remote locations, they shall be approachable by
         means of paved pathways.

7.6.9    Hydrants located in situations where they are likely to be
         damaged by vehicular traffic shall be suitably protected on all
         sides against possible damage.

7.6.10   Hydrants shall be located bearing in mind the attendant fire
         hazards at the different sections of the premises to be
         protected and so as to give most effective service. They shall
         be so distributed as to provide protection for the buildings on
         all sides and need not necessarily be equidistant from each
         other.

         Advantage shall be taken of convenient door and/or window
         openings to place hydrants so that only a minimum length of
         hose is required to reach the openings through which fire
         may be attacked. In case of continuous blank walls, suitable
         provision shall be made on the walls near hydrant posts for
         easy access inside the premises.

7.6.11   At least one hydrant post shall be provided for every 60 m of
         external wall measurement in case of Light Hazard
         Occupancy, for every 45 m in case of Ordinary Hazard
         Occupancy and every 30 m of external wall measurement or
         perimeter of unit battery limit in case of High Hazard
         Occupancy.

         Measurements shall be calculated on the total length of walls
         of all buildings/perimeter of all battery limits to be protected
         except in the case of opposite buildings (other than those of
         High Hazard category) within 22.5 m of each other, where
         the measurement of the shorter opposing wall may be
         omitted.

         Further, all hydrants and monitors should be serially
         numbered.
         NOTE: Notwithstanding the above, hydrants protecting
         utilities and miscellaneous buildings in High hazard risks
         may be spaced at 45 m.

7.6.12   No building shall be deemed to be protected by a hydrant
         unless such hydrant is within 15 m of the building. Where
         any part of a building is normally used for storage purpose or
         where hazardous processes are carried out, there shall be two
         single or one double headed hydrant within 15 m of the
         building, the layout being such that two jets of water can be
         played simultaneously on the highest point of the roof.

         In case of Buildings/Plants occupied for High Hazard process
         or storages, the above-specified distance may be increased to
         22.5 m.

         In case of buildings having roofs other than RCC, it is
         advisable to provide hydrants at the roof level along with
         access staircases in order to fight the fire by breaking open
         the roofs, if necessary.

7.6.13   Hydrant heads shall be positioned at distances not less than 2
         m from the face of the building or edge of the storage plot to
         be protected except in the case of high hazard occupancies
         wherein the hydrant heads shall be located not less than 7.5
         m from the face of the building, edge of the storage plot or
         from the plant battery limits.

7.6.14   In case where, owing to the size or layout of the building, or
         building being divided by internal walls, any point within the
         building is at a distance of more than 45 m from an external
         fire hydrant, an internal hydrant system shall be provided so
         that no portion of the floor is more than 45 m from an
         external hydrant or 30 m from an internal hydrant.

         In case of large switchyards, where it is not feasible to lay
         internal hydrants, alternate hydrants may be replaced by
         monitors of suitable size.

         N.B: Distance of 45 m indicated above shall be increased to
         60 m for light hazard occupancies and reduced to 30 m for
         high hazard occupancies.
7.6.15    In case of storeyed buildings, satisfactory access shall be
          provided to all parts of each floor by means of incombustible
          internal or external staircases. Normally, a minimum of two
          such staircases will be needed per compartment, but in case
          the area of the compartment exceeds 2,000 sq. m., an
          additional staircase shall be provided for every additional
          1,500 sq. m. or part thereof. On the other hand, if a
          compartment has a floor area of less than 500 sq. m., one
          access staircase shall be acceptable. The access staircases
          shall be so located that, as far as possible, no part of each
          floor is more than 30 m from the nearest staircase. Where it
          is not possible to locate the staircase in the aforesaid manner,
          the Committee may suggest alternative methods for
          protection of such large upper floors. External access
          staircases shall be open to sky.

          The staircases shall conform to the following -

7.6.15.1 Internal staircases shall be so located that atleast one of its
         enclosing walls is an external wall of the building. A door
         opening shall be provided in this external wall at ground
         floor level. The enclosing walls shall be of brick work atleast
         230 mm thick or reinforced concrete atleast 100 mm thick
         carried through and atleast 450 mm above the roof of the
         building, unless the roof is of jack arch or reinforced concrete
         construction in which case the walls need be carried upto the
         roof only. Every opening from the staircase to any portion of
         the building or to a roof used as a floor shall be fitted with a
         single fireproof door.

          N.B: The above rule will not apply to buildings, the upper
          floors of which are occupied by offices, air washer plants,
          rest rooms, cloak rooms, canteen and the like.

7.6.15.2 External staircases without side covering need not have
         openings at each floor level protected by single fireproof
         doors. However, if external staircases are enclosed, they
         shall be considered equivalent to internal staircases.

          NOTE: There shall be no equipment within 2 m of the
          staircases and/or its landings.
7.6.15.3 Staircases shall be not less than 750 mm clear width with
         treads not less than and risers not more than 200 mm and
         under not circumstances shall the staircase have an
         inclination of more than 60 degrees to the horizontal.

         NOTE: Iron rung ladders or spiral staircases shall not be
         acceptable.

7.6.15.4 In the case of enclosed staircases, all windows therein falling
         within 3 m of any other openings in the building shall
         normally be protected by wired glass in steel framework in
         accordance with the Committee's regulations. Conversely, in
         the case of open-sided staircases, window and door openings
         of the building falling within 3 m of the staircase shall
         normally be protected by wired glass in steel framework and
         single fireproof door respectively in accordance with the
         Committee's regulations.

         NOTE: The latter part of this rule shall not apply to
         buildings, which are essentially open sided.

7.6.15.5 Exits to the access staircases shall always be kept open
         during working hours. During non-working hours, the exits
         may be locked from the staircase side only. Locks of all exits
         shall have one master key, which shall be available either at
         the main gate, or any other prominent and easily accessible
         location known to the fire fighting personnel. Alternatively,
         the key shall be kept in a glass-fronted box or in the hose box
         on the staircase landing.

7.6.15.6 A hydrant shall be provided on every floor landing which
         shall not be less than 1.5 m x 1 m. The mains feeding the
         landing hydrants shall be provided with a cut-off valve at
         ground level (also see N.B.4 under rule 7.5.10 and rule
         7.7.3.3)

7.6.16   Specific requirements for provisions of monitors in plant
         areas -

7.6.16.1 Tall columns, structure, towers and equipment where it may
         not be possible to provide access staircases with hydrants on
         landing thereof as per rule 7.6.15, will be considered as
         protected by hydrants at ground level, provided they are less
         than 15 m in height. When the height exceeds 15 m, the
         concerned hydrants shall be replaced by monitors.

7.6.16.2 Alternate hydrants for protection of loading unloading bays,
         rail/truck gantries shall be replaced by water/foam monitors.

7.6.17   PROTECTION OF BASEMENTS:

7.6.17.1 Staircases/ramps shall provide access to all parts of the
         basement directly from the outside of the building at ground
         level. The number and location of the staircases/ramps shall
         be such that no part of the basement is more than 45 metres
         from the nearest staircase/ramp.

7.6.17.2 It is recommended that the staircase/ramp be provided with
         emergency lighting facilities. Where maintenance of
         illumination depends upon changing from one energy source
         to another, there shall be no appreciable interruption of
         illumination during changeover. Where emergency lighting is
         provided by means of electric generator, a delay of not more

              fenced enclosures nor can hydrant mains pass through
              such enclosures.

7.7      HOSE PIPES AND NOZZLES -

7.7.1    In the case of yard hydrants, hose pipes and nozzles shall be
         installed either in central hose stations which shall be of the
         type illustrated in figure no. 12 (which enables the condition
          and quantity of hose, nozzles, etc. to be checked over at a
          glance and ensures that other useful equipment is ready at
          hand in the event of a fire) or near each hydrant in glass
          fronted hose boxes of suitable design.

          N.B. Locations and number of hose stations will depend upon
          several factors such as fire loads, accessibility and positions
          of watch posts. Prior approval of the Committee shall,
          therefore, be obtained regarding locations of the hose stations
          before they are constructed.

7.7.2     In case of hydrants on upper floors or internal hydrants,
          hosepipes and nozzles shall necessarily be installed near each
          hydrant in glass fronted hose boxes of suitable design.

7.7.3     REQUIREMENTS OF HOSE PIPES:

7.7.3.1   If hose is kept in central hose stations, for each of the first ten
          hydrants in the compound of the premises (a double headed
          hydrant counting as two except where they are provided as a
          standard practice throughout the system), two lengths of hose
          15 m each and an additional 15 m length for each hydrant in
          excess of ten, shall be provided.

          NOTE: In case of system having more than 55 hydrant
          outlets, the total number of hose lengths required may be
          limited to 55 plus 20 percent of the number of hydrant outlets
          in excess of 55. Where a fire engine is maintained on the
          premises manned by a whole time fire brigade, the number of
          hose, pipes required (including those on the engine) would be
          55 plus 10 percent of the number of outlets in excess of 55.

7.7.3.2   If hose is kept in hose boxes alongside hydrants, each box
          shall contain two lengths of 15 m each.

7.7.3.3   For use with each hydrant on staircase landing or with each
          internal hydrant, two lengths of hose 7.5 m shall be provided.
          In case of basement hydrants, two lengths of hose 15 m shall
          be provided.

7.7.3.4   All hoses shall be of 63 mm diameter of either of the
          following types -

                 Standards IS: 8423.

7.7.3.5   Ordinary rubber lined woven-jacketed hose complying with
          the specification of Type B of Indian Standards IS: 636 may
          be permitted to be used in lieu of the above upto a maximum
          of 50 % of the total hose requirements of the hydrant system.

7.7.3.6   All couplings shall be of the instantaneous spring-lock type
          and the nozzles shall be of not less than 16 mm in diameter,
          nor more than 25 mm in diameter except in case of high
          hazard occupancies where the maximum nozzle diameter
          may be 32 mm subject to the approval of the Committee. All
          couplings, branch pipes and nozzles shall be of gunmetal or
          stainless steel and shall otherwise comply with IS: 903, 1984.

7.7.3.7   Hose shall be attached to the coupling (other than of ferrule
          type) in the following manner -

          Each half of the coupling shall have two 5 mm diameter
          holes drilled in the tail. The hose shall be first fixed to the tail
          of the coupling with copper rivets then served or bound with
          1.5 mm galvanised mild steel or copper wire for a length of
          50 mm which will extend to the outer ends of the grooving
          on the coupling tail over the galvanised mild steel or copper
          wire a leather or equally protective band shall be bound with
          four strands of 1.12 mm galvanised mild steel or copper wire
          at each end of the band. The protective band shall be carried
          beyond the tail of the coupling to prevent leaking.

          Copper wire, if used, shall be softened before being used.

          Couplings attached to the hose otherwise than by copper
          rivets shall not be accepted, as they are apt to become
          dislodged under pressure.
7.7.3.8   Spare hose to the extent of 10 percent of the above
          requirements, with a minimum quantity of 30 m shall be
          always kept readily available. Such spare hose shall also be
          in 15-m lengths, readily attached to couplings.

          NOTE: In calculating the number of lengths of hose required
          under the above scale, any fraction of a number shall be
          counted as one.

7.7.3.9   It is recommended that a system of marking and numbering
          hose be arranged so that the various lengths are easily
          recognisable.

7.7.3.10 In central hose stations and hose boxes a tin containing a set
         of spare rubber rings packed in french chalk shall be kept.

7.7.3.11 Central hose stations and hose boxes shall be so arranged that
         hose is not exposed to the sunrays.

7.7.3.12 All central hose stations or hose boxes, when provided with
         locks shall have one master key which shall be available
         either at the main gate or any other prominent and easily
         accessible location known to the fire fighting personnel.

7.7.4     REQUIREMENTS OF NOZZLES:

7.7.4.1   The number of nozzles to be provided shall be equivalent to
          half the number of hose pipes installed on the premises.

7.7.4.2   In locations where a jet of water directed from a normal type
          nozzle is likely to cause more harm than good or where a
          gentle spray of water is essential for the extinguishment of a
          fire, a fog type or a spray type of nozzle complying with IS:
          2871 shall be used.

7.7.4.3   Spare nozzles to the extent of 10 % of the above
          requirements, with a minimum of two, shall always be kept
          readily available.

7.8       FOAM COMPOUND:
          Foam systems shall conform to NFPA 11 and 11A, 16A
          and/or relevant BIS specifications-IS: 12835 or LPC rules for
        Foam Systems. The stock of foam compound to be
        maintained shall be equivalent to at least two times the
        requirement of the tank needing maximum quantity of foam.
        Foam Compound shall be chemically neutral (PH 6.5 to 7.5)

7.9     FIRE FIGHTING PERSONNEL:

7.9.1   As the efficiency of a hydrant service and/or of internal
        appliances depends upon the manner and speed with which
        they are brought into use and the ability with which the effort
        is directed, a squad consisting of watch and ward personnel,
        fire pump men and departmental supervisors and/or
        operatives trained in the operation of the fire service shall be
        maintained on the premises round the clock. The number of
        personnel constituting the squad shall necessarily depend
        upon the size of the risk, but in no case shall be less than
        eight trained persons be available at any time during the day
        or night. Minimum number of trained persons required may
        be further reduced to six in case of automatic pressurised
        hydrant systems.

7.9.2   Squad leaders shall preferably be recognised government
        institution trained and their usefulness would be considerably
        enhanced if they reside on the premises.

7.9.3   Squad personnel shall be provided with clothing and
        equipment including helmets, belts and boots, preferably
        gumboots.

7.9.4   A muster roll showing the duties allocated to each member of
        the brigade shall be prepared and copies supplied to each
        squad leader as well as pasted in convenient places
        throughout the premises, so as to be quickly available for
        reference in case of emergency.

7.9.5   Practice drills shall take place weekly and it is a condition of
        the approval by the Committee to the discount for hydrant
        service that wet drills shall be carried out at intervals of not
        more than a fort-night and that the entire squad on duty shall
        turn out during the visits of the committee‟s Inspectors.
7.9.6   During wet drills, hydrants (including those of upper floors),
        hose pipes and nozzles, shall be taken into use in rotation
          so that the efficacy of these appliances would be
          automatically checked and any defects observed, set right.

7.9.7     A register shall be kept as per Appendix V showing details of
          all practices and defects, if any, reported in the installation.
          This register shall be open to examination by the
          Committee‟s Inspectorate.

7.9.8     The services of the pump man (see 7.10.1.1.1) could be
          profitably utilised for the maintenance of all fire fighting
          appliances (including hand appliances - See 4.1.5.1.1). He
          shall also be thoroughly conversant with the locations of all
          appliances, particularly of hydrant cut-off valves so that in an
          eventuality he would be of assistance to the
          factory‟s fire brigade or the Town‟s fire brigade.

7.9.9     Keys of all doors in the factory premises shall always be
          available at the main gate.

7.9.10    It is recommended that fire pump room(s) and the main
          gate(s) of all factory premises be connected to all
          manufacturing sections through the internal telephone
          system. Telephones interlinked to this system may
          also be put up in proper cubicles at convenient locations near
          godown ranges and other strategic points. This would effect
          saving of valuable time in an emergency to alert the fire
          fighting personnel and the pump man.

7.10      MAINTENANCE:

7.10.1    PUMPS:

7.10.1.1 GENERAL:

7.10.1.1.1 A trained pump man (see 7.9.8) shall be available on all
           shifts and at all hours of the day and night to operate the
           pumps as and when required.

7.10.1.1.2 Pump sets shall be run for atleast five minutes every day.

7.10.1.1.3 The level of water in the priming tank shall be checked daily
           to ensure that the foot valve of the pump is not leaking.
   7.10.1.1.4 All pump glands shall be maintained in efficient working
              condition and the packing renewed as required to maintain
              efficiency.

   7.10.1.1.5 Suction and delivery valves shall be examined once every
              six months, particularly where sand or other objectionable
              matter is liable to be drawn through the pump suction.

   7.10.1.1.6 All working parts shall be kept clean and lightly oiled as
              cleanliness greatly adds to efficiency. Any necessary repairs
              shall be put in hand and carried out immediately.

   7.10.1.2   STEAM PUMPS:

   7.10.1.2.1 The steam cylinders of pumps shall always be kept warm
              and efficient draining arrangements provided.

   7.10.1.2.2 A minimum of two sets of piston and bucket rings shall be
              provided.

   7.10.1.2.3 Small parts such as snifting valves, cushioning valves and
              petcocks shall have special attention because faults in these
              valves cause the pump to knock badly and lose efficiency.

   7.10.1.3   ELECTRICALLY DRIVEN PUMPS:

   7.10.1.3.1 The bearing grease cup shall be checked once every week
              and refilled with fresh grease, if necessary.

   7.10.1.3.2 Starter contacts shall be cleaned once every week.

   7.10.1.3.3 Insulation resistance of pump motor circuit shall be
              examined once every six months and record of results shall
              be maintained.

7.10.2 MAINS:

   7.10.2.1   Hydrant mains shall be tested once a fortnight with a pump
              delivering at its maximum pressure, with all hydrant valves
              closed and, thereafter, a running test with two or more hose
              lines each 30 m long operating shall be carried out. This
              checks the efficiency of the pump as well as the tightness of
              the hydrant mains (See Rule 7.9 also).
7.10.2.2   All cut-off valves shall be operated and oiled, if necessary,
           once a month.

7.10.2.3   Cut-off valves shall be thoroughly overhauled annually to
           remove sludge and other foreign matter collected in the
           valve seating.

7.10.3     HYDRANTS:

7.10.3.1   All hydrants shall be examined systematically once a week
           to ensure that valves and spring catches are maintained in
           good condition and all brass parts polished.

7.10.3.2   Spare washers shall be kept for hydrant valve seats.

7.10.3.3   It is recommended that the painting of standpoints be carried
           out annually.

7.10.4     HOSE PIPES AND NOZZLES:

7.10.4.1   All hose boxes/hose stations shall be inspected externally
           once every week to ensure that the equipment installed
           therein is intact. Further, the hose boxes/hose stations shall
           be cleaned internally and externally once a month.

7.10.4.2   When the hose gets worn out at the tail end of the
           coupling(s), it is permissible to cut the end(s) of the hose.
           However should the lengths of the hose after cutting(s) fall
           below 90 percent of its original, i.e. 15 m or 7.5 m the hose
           shall be discarded.

7.10.4.3   A Hose Register shall be kept showing the history of each
           length. Information such as date purchased, date brought
           into use, date cut (if reduced in length), is useful and a
           column shall be provided for remarks by the Committee‟s
           Inspectors to whose inspection the Hose Register shall be
           open.

7.10.4.4   Any hose becoming inefficient through use, neglect or from
           any other cause, shall be discarded.
7.10.4.5   Fire protection hose shall not be used for purposes other
           than fire protection and drill. All concerns are advised to
           keep a supply of cheap hose for watering paths, washing out
           or filling boilers, etc. Such hose shall not be mixed with
           fire protection hose but kept in an entirely separate place.

7.10.4.6   It is recommended that hose couplings and branch pipes be
           polished once a fortnight.

7.11       Considerable diversity of practice has been noticed in the
           attention paid to the drying and storing of hose and the
           following suggestions in this connection shall be carried
           out:

           After use, hose to be thoroughly washed in clean water and
           then thoroughly dried. A rack or some similar contrivance
           atleast 10 m high to be provided so that, after cleaning, hose
           may be suspended to drain and dry evenly.

           This is to be done in the shade and not in the sunshine so
           that the hose is evenly dried inside and out. Care to be
           exercised that it is not removed until it is thoroughly dry in
           all places. The hose to be then thoroughly brushed with a
           hard bristle or wire brush, and re-rolled, care being taken to
           choose a dry and clean place whereon to roll it; and replace
           in the boxes or hose stations.

           Care to be taken after washing that the hose does not touch
           the ground, where it might be soiled.

           Hose to be rolled up evenly and carefully, the female or
           spring coupling end being in the centre. In this manner the
           spring clips, when grasped one in each hand, form a `reel‟
           and the hose can be quickly run out in the event of fire. OR
           ALTERNATIVELY

           The hose to be doubled in the centre of its length and rolled
           up evenly from the fold. Both the Male and Female
           couplings will then be on the outside of the roll. This
           permits the nozzle being attached to the hose while being
           stored in readiness for use, and the hose runs out without
           twisting.
7.11     MEASURES TO BE TAKEN WHERE THE INSTALLATION
         IS FOR ANY REASON TEMPORARILY INOPERATIVE:

         any reason whatsoever, the entire system shall not be
         rendered inoperative but the particular section only shall be
         isolated by closing the necessary cut-off valves. If, however,
         it is not possible to complete the replacement before
         nightfall, the cut-off valves shall not be left closed overnight.
         Instead, blank flanges shall be provided at the point where
         the component has been removed so that the entire system,
         other than the component, which has been removed, would
         remain operative through the night.

7.11.3   Only one compartment of the reservoir shall be emptied out
         at a time of cleaning or repair work.

7.11.4   If the foot valve of the suction line is removed for
         cleaning/repairs, it shall, as far as practicable, be replaced
         before nightfall.

7.11.5   If the pump is expected to be inoperative for more than 72
         hours, every effort shall be made to connect the service water
         supply to the hydrant system for the duration the pump is
         inoperative.

7.11.6   If the hydrant service is to be extended, the extended portion
         shall be first laid and, thereafter, the connection between the
         existing system and the extension shall be carried out
         expeditiously, so that the entire system is not left inoperative
         overnight.

NOTE: - In applying this table the height of the Highest Sprinkler above
the Pressure Gauge must be ascertained and the pressure to be
allowed for such height will be obtained by reference to the table.
For example, if the gauge records a pressure of 4.25 Kg./cm2, and the
highest sprinkler is 28 m above the gauge, there will be a pressure of,
say, 1.45 Kg./cm2 on the highest sprinkler.
