1.16          HEALTH AND SAFETY

1.16.1        General

              The platform must be designed and constructed to offer the space and strength
              corresponding to the maximum number of persons and the rated load of the lift.

              Design and construct the platform so that its structural features do not obstruct or impede
              access and use by disabled persons and so as to allow any appropriate adjustments
              intended to facilitate its use by them.

              The means of suspension and/or support of the platform, its attachments and any
              terminal parts thereof must be selected and designed so as to ensure an adequate level
              of overall safety and to minimize the risk of the platform falling, taking into account the
              conditions of use, the materials used and the conditions of manufacture.

              Where ropes or chains are used to suspend the platform, there must be at least two
              independent cables or chains, each with its own anchorage system. Such ropes and
              chains must have no joins or splices except where necessary for fixing or forming a loop.



Ministry of Education - STANDARD 2006                             7917 POWERED LIFTING PLATFORMS Page 3
              Platforms must be so designed, constructed and installed as to prevent normal starting if
              the rated load or rated speed is exceeded.

              Suspended platforms must be equipped with an overspeed governor.

              Platforms must be equipped with speed-monitoring and speed-limiting.

              Platforms driven by friction sheaves must be designed so as to ensure stability of the
              traction cables on the traction sheave.

              Platforms must have their own individual hoisting machinery.

              The platform machinery and the associated devices of a platform elevator must not be
              accessible except for maintenance and in emergencies.

              The controls intended for use by unaccompanied disabled persons must be designed
              and located accordingly.

              The function of the controls must be clearly indicated.

              Electrical equipment must be so installed and connected that:
              - there can be no possible confusion with circuits which do not have any direct connection
                with the platform
              - the power supply can be switched while on load
              - movements of the platform are dependent on electrical safety devices in a separate
                electrical safety circuit
              - a fault in the electrical installation does not give rise to a dangerous situation
              - a short circuit or open circuit of the electrical safety circuit(s) does not give rise to a
                dangerous situation.

1.16.2        Hazards To Persons Outside The Hoistway

              The platform must be designed and constructed to ensure that the space beyond which
              the platform normally travels is inaccessible except for maintenance or in emergencies.
              Before a person enters that space, normal use of the lift must be made impossible.

              The platform must be designed and constructed to prevent the risk of crushing when the
              platform is in one of its extreme positions. The objective will be achieved by means of
              free space or refuge beyond the extreme positions. However, in specific cases, prior
              approval where this solution is impossible to fulfil, other appropriate means may be
              provided to avoid this risk.

              The landings at the entrance and exit of the platform must be equipped with landing
              doors of adequate mechanical resistance for the conditions of use and misuse envisaged.
              An interlocking device must prevent during normal operation:
              - starting movement of the platform, whether or not deliberately activated, unless all
              landing doors are shut and locked
              - the opening of a landing door when the platform is still moving.

1.16.3        Hazards To Persons On The Platform

              Lift platforms must be completely enclosed by full-length flush hoistway walls.

              In the event of a power cut or failure of components the lift must have devices to prevent
              free fall or uncontrolled movements of the platform. The device preventing the free fall of
              the platform must be independent of the means of suspension of the platform. This
              device must be able to stop the platform at its rated load and at the maximum speed
              anticipated by the installer of the platform. Any stop occasioned by this device must not
              cause deceleration harmful to the occupants whatever the load conditions.

              Buffers must be installed between the bottom of the shaft and the floor of the platform. In
              this case, the free pit space referred must be measured with the buffers totally
              compressed. This requirement does not apply where the platform cannot enter the free


Ministry of Education - STANDARD 2006                             7917 POWERED LIFTING PLATFORMS Page 4
              space referred by reason of the design of the drive system.

              Platforms must be so designed and constructed as to make it impossible for them to be
              set in motion if the safety control devices not all in an operational position.

1.16.4        Other Hazards

              Landing doors, where they have to contribute to the protection of the building against fire,
              including those with glass parts, must be suitably resistant to fire in terms of their integrity
              and their properties with regard to insulation (containment of flames) and the
              transmission of heat (thermal radiation).

              Counterweights must be so installed as to avoid any risk, including such as colliding with
              or falling on to the platform.

              Platforms must be so designed and constructed that, in the event of the machinery
              temperature exceeding the maximum set by the installer of the platform machinery, they
              can complete movements in progress but refuse new commands.

              Platform installations must be designed and constructed to ensure sufficient ventilation
              for passengers, even in the event of a prolonged stoppage.

              The platform installation must be adequately lit whenever in use or whenever a door is
              opened; there must also be emergency lighting.

              The platform must be adequately lit by an emergency lighting luminaire in the event of the
              loss of mains electricity supply.

              Platforms must be equipped with means enabling people to be released and evacuated.

              Platforms must be fitted with two-way means of communication allowing permanent
              contact with a rescue service.

              The means of two-way (emergency) communication must be designed and constructed
              so as to function even without the normal power supply. Their period of operation should
              be long enough to allow normal operation of the rescue procedure.


1.16.5        Marking

              Each platform must bear an easily visible plate clearly showing the rated load in
              kilograms and the maximum number of passengers that may be carried.

              If the platform is designed to allow people trapped in the hoistway to escape without
              outside help, the relevant instructions must be clear and visible on the platform.

1.16.6        Instructions For Use

              The safety components must be accompanied by an instruction manual so that:
              assembly; connection; adjustment; and maintenance can be carried out effectively and
              without danger.

              Each platform installation must be accompanied by documentation which shall contain at
              least:
              - an instruction manual containing the plans and diagrams necessary for normal use and
              relating to maintenance, inspection, repair, periodic checks and the rescue operations.
              - a logbook in which repairs and, where appropriate, periodic checks can be noted.

1.16.7        Manual (Emergency) Operation
              Provide for manual operation in the event of loss of the automatic control system
              operation.




Ministry of Education - STANDARD 2006                               7917 POWERED LIFTING PLATFORMS Page 5
1.17          PRECAUTIONS (NOISE/NUISANCE)
              Provide details of operational noise of the platform installation and minimise breakout of
              noise into occupied spaces, to less than PNC43 within 3000mm of the hoistway or
              machinery room.


1.18          MAINTENANCE MANUALS
              Supply three copies of a manual containing all technical data and drawings necessary for
              the efficient operation and maintenance for each of the installations.

              The Manuals will be used by the Owner as a record of the installation as installed, how to
