COGNITIVE OBJECTIVES

     CO: Identify key components of PPE and SCBA
     CO: Identify maintenance procedures for PPE and SCBA

PERFORMANCE OBJECTIVES:

     PO: Don, doff, inspect and operate SCBA under normal and emergency
         conditions
     PO: Don, doff, and inspect PPE

ATTENTION:      The use of protective clothing and self-contained breathing
                apparatus reduces the risks of fire fighting injuries.
                Firefighter safety though, is not guaranteed merely because
                of the quality of the equipment and the fact that it is being
                worn.

OVERVIEW:        In this unit you will learn about the use and limitations of
                 personal protective equipment (PPE) and the requirements
                 of the wearer.

MOTIVATION:       Extensive training in the use and maintenance of this
                 equipment is required to ensure that the equipment will
                 provide the optimum protection expected. Even though
                 the equipment is quality equipment and the wearer has
                 had extensive training, all protective equipment has
                 inherent limitations.

TRANSITION:      We will begin discussing the function of PPE.

   EVALUATION: Appraisal and written test

        (a) Helmet (NFPA 1971: Standard on Protective Ensemble for Structural Fire
            Fighting)
            1 Protects the head, face, and eyes from:
               a Impact injuries
               b Heat and cold
               c   Hot water and embers, wide brim provides this protection
            2 Limitations:
               a All helmets must have ear covers, chin straps, face shields, reflective
                   trim, and an energy absorbing system
               b Helmets must be properly secured to the head with all components in
                   place to provide the designed protection
            3 Inspecting helmet check the following
               a Manufacturer’s label
               b Reflective trim, cracks in shell, cleanliness, burns, and signs of melting

                                                                                Notes/Visuals

              c   Energy absorbing system for frays, 1 ¼ inch clearance between webbing
                  and helmet shell
              d Chin strap for frays and functioning properly
              e Face shield for cracks, scratches, and any distortion
              f   Ear covers for cleanliness, burns and fraying
        (b) Eye protection (NFPA 1500)
           1 One of the most common injuries on the fire-ground is to the eyes
           2 Protection provided by
              a Safety glasses
              b Safety goggles
              c   Helmet faceshield
              d SCBA masks
           3 Protects the wearer’s eyes from:
              a Flying particles
              b Chemical splashes
           4 Limitations
              a elmet faceshield provides secondary protection and may not provide
                  required eye protection from flying particles or splashes
              b Other situations where safety glasses or goggles are to be used include
                  station operations (such as welding, grinding, or cutting), vehicle
                  extrication, brush fires, and industrial inspections
              c   Safety glasses or goggles will protect against 85 percent of all eye
                  hazards
        (c) Hearing protection
           1 Protection provided by
              a Earmuffs
              b Intercom/ear protection
              c   Ear plugs (each firefighter should have a personal set)
           2 Protects the wearer from noise-induced damage to the ears when loud
              noises cannot be avoided
           3 Limitations:

              a Earmuffs can compromise protection of the face by making it awkward to
                  use the SCBA and protective hood
              b Earplugs may melt when exposed to intense heat
              c   Hearing protection should be provided to all firefighters and used in
                  accordance with standard operating procedures
        (d) Protective hoods
           1 Protect portions of the firefighter’s ears, neck, and face not covered by the
              SCBA facepiece, ear covers, or coat collar from exposure to extreme heat
           2 Limitations
              a If not worn properly the hood may interfere with face-to-SCBA facepiece
                  seal
              b If not worn properly the hood may obscure the firefighters vision
           3 Inspecting protective hoods

              f   Many environmental hazards
           2 Components of the coat and trousers
              a Outer shell
              b Moisture barrier
              c   Thermal barrier
              d These three barriers trap insulating air that inhibits the transfer of heat
                  from outside to the firefighter’s body
              e Collar (protects neck and throat)

               b Must be worn with structural firefighting clothing during fire fighting
                   operations
     (2) Care of personal protective clothing
        (a) All personal protective clothing should be cleaned in accordance with
           manufacturer’s specifications
        (b) NFPA 1581, Standard on Fire Department Infection Control Program, requires
           personal protective clothing be cleaned and dried at least every six months
        (c) NFPA 1500, Standard on Fire Department Occupational Safety and Health
           Program, requires protective clothing be cleaned using either a cleaning service
           or fire department facility equipped to handle contaminated clothing
        (d) Dirty protective clothing absorbs more heat

          (e) Clean protective clothing will have a better resistance to fire

INTERIM SUMMARY:

b. Given a set of protective clothing and observing all safety precautions, inspect
protective clothing within 10 minutes, with at least 16 out of 17 evaluation elements
performed correctly.

Helmet, Inspect for:

          (a) Cleanliness. (dirt will absorb heat faster than the shell itself)
             1 If dirty, clean with soap and water
             2 If exposed to hydraulic fluid or petroleum products remove from service.
                 Exposure to these type of products reduces the protective properties of the
                 helmet
          (b) Adequate separation between the suspension webbing and the outer shell (at
             least 1 1/4 inches) - if necessary adjust the webbing
          (c) Manufacturer’s label for conformance with standard
             1 Label must be present to comply with standards
             2 If missing, replace helmet or obtain new label from manufacturer
          (d) Cracks in shell - If present, replace the helmet
          (e) Burns or melting - If present, replace helmet

               sewn into turnouts
            2 Dirty turnouts absorb more heat than clean ones
        (b) Manufacturer’s label for conformance with standard
            1 If turnouts do not have a manufacturer’s label then there is no way of telling
               whether they meet NFPA standards
            2 Replace effected coat or trousers
        (c) The presence of the outer shell, the vapor barrier, and the thermal barrier - if

d. Without reference, identify basic facts about the Self Contained Breathing
Apparatus (SCBA).

      (1) The function of the Self Contained Breathing Apparatus (SCBA), (NFPA 1981,
         Open-circuit Self Contained Breathing Apparatus for Fire Fighters)
         (a) The firefighter’s lungs and respiratory tract are more vulnerable to injury than
            any other part of the body
         (b) Fundamental rule should be that no one is permitted to enter the following:
            1 Toxic atmosphere
            2 Interior or exterior fire attack
            3 Below-grade rescue
            4 Hazardous materials emergency
      (2) Environments requiring respiratory protection - Four Common Hazardous
         Atmospheres are as follows: (acronym TOES)
         (a) Toxic atmospheres associated with fire
            1 Exposure to combinations of irritants and toxicants that cannot be predicted
                accurately can be expected
            2 Exposure to combinations of gasses can cause a combined effect that is
                potentially more serious than if each were inhaled separately
            3 Exposure to toxic atmospheres
                a If inhaled, toxic gases may have several harmful effects on the human
                    body
                b Some gases may directly cause disease of the lung tissue
                c   Other gases have no direct harmful effect on the lungs but pass into the
                    bloodstream and to other parts of the body and impair the oxygen-
                    carrying capacity of the red blood cells
                d More deaths occur from carbon monoxide poisoning than from any other

        (b) Oxygen deficient atmosphere
           1 Physiological effects of reduced oxygen
              a Normal breathing air is 21% oxygen concentration
              b Oxygen concentrations below 18% the body will increase respirations
              c   17% oxygen concentration impairment of muscle coordination
              d 12% oxygen concentration dizziness, headache, rapid fatigue
              e 9% oxygen concentration unconsciousness
              f   6% oxygen concentration death from respiratory and heart failure
           2 Oxygen deficient atmospheres may be found in the following areas:
              a Below-grade locations
              b Chemical storage tanks
              c   Grain bins
              d Silos

           1 Cause severe burns to the respiratory tract
           2 May decrease blood pressure and failure of the circulatory system
           3 Possible pulmonary edema (fluid in the lungs) causes death from
               asphyxiation
        (d) Smoke
           1 Suspension of small particles of carbon, tar, and dust
           2 Combination of heated gases
           3 Some particles are irritating, but others are lethal
           4 Size of particle determines how deeply into the respiratory tract it will be
               inhaled
     (3) Protective breathing apparatus limitations
        (a) Limitations of wearer
           1 Physical
               a Physical condition - The wearer must be in sound physical condition in
                   order to maximize the work that can be performed and to stretch the air
                   supply as far as possible
               b Agility - Wearing an SCBA restricts the wearer’s movements and affects
                   his or her balance; Good agility will overcome these obstacles
               c   Facial features - The shape and contour of the face will affect the
                   wearers ability to get a good face-to-face piece seal
           2 Medical - Neurological function
               a Good motor coordination is necessary for operating in protective
                   breathing equipment
               b Muscular/skeletal condition - The firefighter must have the physical
                   strength and size required to wear the protective equipment and to
                   perform necessary tasks
               c   Cardiovascular condition - Poor cardiovascular conditioning can result in
                   heart attacks, strokes, or other related problems during strenuous
                   activities
               d Respiratory functioning - Proper respiratory functioning will maximize the
                   wearer’s operation time in an SCBA

                                               Page 13 of 26
Lesson Plan – PPE / SCBA
                                                                                  Notes/Visuals

           3 Mental
               a Adequate training in equipment use - The firefighter must be
                   knowledgeable in every aspect of protective breathing apparatus use
               b Self confidence - The firefighter’s belief in his or her ability will have an
                   extremely positive overall effect on the actions that are performed
               c   Emotional stability - The ability to maintain control in an excited or high
                   stress environment will reduce the chances of a serious mistake being
                   made
        (b) Limitations of equipment
           1 Limited visibility - The face piece reduces peripheral vision
           2 Decreased ability to communicate - The face piece hinders voice
               communication
           3 Increased weight - Depending on the model and make, the protective
               breathing equipment adds 25 to 35 pounds of weight to the firefighter
           4 Decreased mobility - The increase in weight and the splinting effect caused
               by the back plate and harness straps reduce the firefighter’s mobility
        (c) Limitations of air supply
           1 Physical condition of user - If the wearer is in poor physical condition, the air
               supply will be expended faster
           2 Degree of physical exertion - The harder the firefighter exerts him or herself,
               the faster the air supply is expended
           3 Emotional stability - The respiration rate of a firefighter will increase when he
               or she becomes excited and the air will be used faster
           4 Condition of apparatus - Minor leaks and poorly adjusted regulators result in
               excess air loss
           5 Cylinder pressure - If the cylinder is not filled to capacity, the amount of
               working time will be reduced proportionately
           6 Training and experience - Properly trained and highly experienced
               personnel will be able to draw the maximum air supply from a cylinder
     (4) Four basic SCBA components: (acronym BARF)
        (a) Backpack (back plate) and harness assembly

                                             Page 14 of 26
Lesson Plan – PPE / SCBA
                                                                                Notes/Visuals

           1 Designed to hold the air cylinder on the firefighter’s back as comfortably and
              securely as possible
           2 Adjustable harness straps provide a secure fit
           3 Waist straps are designed to help properly distribute the weight
        (b) Air cylinder assembly
           1 Constitutes the main weight of the SCBA
              a Weight varies with manufacture and materials used
                  1 Steel and aluminum (hydrostatically tested every 5 years)
                  2 Composite materials (hydrostatically tested every 3 years)
              b Most common sizes found in the fire service
                  1 30 minute cylinder contains 45 cubic feet of breathing air at 2,216 psi
                  2 60 minute cylinder contains 87 cubic feet of breathing air at 4,500 psi
           2 Cylinder valve
           3 Pressure gauge
        (c) Regulator assembly
           1 Reduces the high pressure air from the cylinder to slightly above
              atmospheric pressure
           2 Controls the flow of air to the face piece
           3 May have two valves
              a Mainline valve -- to control the flow of air from the cylinder to the
                  regulator (not present on Interspiro air packs)
              b By-pass valve -- allows air to by-pass the regulator and flow directly from
                  the cylinder into the face piece
           4 Has a remote/regulator pressure gauge that shows air pressure remaining in
              the cylinder
              a Remote/Regulator pressure gauge should read within 100 psi of the
                  cylinder gauge
              b Pressure readings are most accurate when the cylinder is full - always
                  go with the lower of the two readings
           5 All units have an audible alarm that sounds when cylinder pressure
              decreases to ¼ of maximum pressure

        (d) Facepiece assembly
           1 Provides protection from facial and respiratory burns
           2 Holds cool breathing air to the wearer’s face
           3 Facepiece consists of:
              a Facepiece lens (clear safety plastic)
              b Low pressure hose
              c   Flexible rubber mask
              d Head harness
              e Speech diaphragm
           4 Improperly sealed or fogged lens can be a problem
              a External fogging
                  1 Occurs when condensation collects on lens
                  2 To correct wipe off condensation
              b Internal fogging
                  1 Occurs when exhaled air condenses inside the lens
                  2 Use of a nosecup, applying an antifogging chemical, or operating the
                     by-pass valve will help correct this problem
     (5) Personal Alert Safety Systems (PASS)
        (a) PASS devices are designed to assist rescuers in the following:
           1 Locating downed firefighters
           2 Locating disoriented firefighters
        (b) PASS should be worn on the SCBA or coat
        (c) Should be turned on before entering a structure
        (d) PASS device can be activated in one of two ways
           1 Manually
           2 Automatically if firefighter remains motionless for 30 seconds
        (e) Recommendations for use of PASS device include the following:
           1 Meets NFPA 1982
           2 Test PASS at least weekly
           3 Retrain every 6 months
           4 Turn on before entering hazardous atmosphere

             5 Turn PASS off once downed firefighter is found



e. Given a PASS Device, SCBA, checklist, and observing all safety precautions, place
the PASS Device and one of the following SCBAs in a safe condition for immediate
use within 10 minutes: Interspiro with at least 28 out of 29 evaluation elements
performed correctly; Scott with at least 30 out of 31 evaluation elements performed
correctly.

There are many different makes and models of SCBA used in the fire service

INTERIM SUMMARY:

g. Given a SCBA and necessary materials, perform and document routine maintenance
of the SCBA while observing all safety precautions, with at least 13 out of 14
evaluation elements performed correctly.

     (1) Re-servicing air cylinders (wear appropriate safety equipment; helmet, eye
        protection, hearing protection, and gloves)
        (a) Check cylinder condition and hydrostatic test date
        (b) Place cylinder in fragmentation deflector, then check for “O-ring”
        (c) Connect high pressure servicing hose to cylinder (close bleed valve)
        (d) Open SCBA cylinder valve
        (e) Open valve on charging hose
        (f) Open valve on cascade system bank that has the least pressure (ensure
           pressure is higher than that of the bottle)
        (g) Open fill valve
        (h) When pressure is equalized close fill valve and valve to cascade bank
        (i) Repeat the same steps with the next cascade bank, moving from the bank with
           the lowest pressure to the highest, until cylinder is completely charged
        (j) When cylinder is fully charged, close all cascade system valves
        (k) Close cylinder valve, bleeding off residual pressure
        (l) If pressure is not bled off o-ring will be damaged
        (m)Disconnect high-pressure hose from cylinder
        (n) Remove full cylinder from fragmentation deflector
     (2) Cleaning SCBA
        (a) Used mild soap recommended by the manufacturer, warm water, and wipe dry
        (b) Disassemble facepiece, breathing valve (Interspiro) or regulator (Scott) and

            clean using posted cleaning procedures for appropriate SCBA type
         (c) Sign off SCBA checklist and document any discrepancies found with the SCBA
         (d) Reassemble SCBA components and return SCBA to assigned location for next
            use

h. Given the emergency operations trainer (EOT), while wearing PPE and SCBA,
observing all safety precautions, perform emergency procedures in the event of SCBA
failure within 10 minutes and then perform two person cylinder change, with at least
17 out of 18 evaluation elements performed correctly.

      (1) Perform horizontal entry procedures through initial opening
         (a) Don SCBA (perform safety checks)
         (b) Enter EOT head first (removed SCBA only as last resort)
         (c) Any time SCBA removed, re-don as soon as possible
      (2) Perform breathing valve failure procedures
         (a) Restricted / no air flow
            1 Check remote/regulator pressure gauge
            2 Check to ensure cylinder valve is fully opened
            3 Open and close bypass/purge valve appropriately to breathe
         (b) Restricted passage
            1 Proceed head first through restricted passage

        (d) Exit EOT
        (e) Demonstrate methods for conserving air
           1 Controlled breathing
           2 Skip breathing
        (f) Two firefighter cylinder change
           1 Wearer opens Spiro-hatch (Interspiro) or removes breathing valve (Scott)
           2 Person performing cylinder change does the following:
              a Close air cylinder valve
              b Disconnect air hose from cylinder and remove from back-plate; DO NOT
                  CROSS THREAD
              c   Check air hose coupling for presence of and damage to O-ring
              d Place a fully charged cylinder in wearer’s back-plate
