Transcript and Presenter's Notes

Title: SCBA


1
SCBA
  • Orientation and Annual Refresher Training

2
Introduction
  • SCBA are one of the most effective and
    potentially hazardous pieces of equipment used in
    the fire service. They allow us to go into
    extremely hazardous situations and may give a
    false sense of security.
  • It is extremely important to
  • Know their limitations and uses
  • Understand how they operate
  • Know how to maintain and check them
  • Be familiar with the packs safety features
  • Be able to use the pack in zero visibility
    environments

3
Introduction
  • Values and Expectations
  • Use good judgment and promote safety at all times
  • Obey the law follow appropriate directives and
    rules
  • Protect your co-workers welfare
  • Work competently
  • Be pro-active

4
Course Objectives
  • Describe how to recognize medical signs and
    symptoms that may limit or prevent the effective
    use of the respirators
  • Describe why the respirator is necessary and how
    improper fit, usage, or maintenance can
    compromise the protective effect of the
    respirator.
  • Describe what the limitations and capabilities of
    the respirator are.

5
Course Objectives Cont.
  • Demonstrate how to inspect, put on and remove,
    use and check the seals of the respirator.
  • Demonstrate how to use the respirator effectively
    in emergency situations, including situations in
    which the respirator malfunctions.
  • Demonstrate the procedures for maintenance and
    storage of the respirator.

6
OVERVIEW
  • Fundamentals
  • Regulations
  • Respiratory Safety
  • Pack Familiarization
  • Inspection
  • Maintenance
  • Bottle Filling
  • Operations

7
Regulations
  • OSHA Respiratory Protection Standard
  • 29 CFR 1910.134-Respiratory protection
    requirements
  • NFPA
  • 1404-Standard for Fire Service Respiratory
    Protection Training
  • 1852- Standard on Selection, Care, and
    Maintenance of Open-Circuit Self-Contained
    Breathing Apparatus

8
Respiratory Safety
  • Hazards in IDLH Atmospheres
  • Toxic gases
  • CO
  • Hydrogen cyanide
  • Other products of combustion
  • Heated gases
  • Diminished Oxygen

9
Respiratory Safety
  • Limitations and Capabilities of Respirator
  • Provides approximately 45 minutes of supplies air
  • No protection from liquids, vapors or gases that
    are toxic by absorption
  • Malfunction, misuse, or running out of air may
    result in severe injury or death
  • Malfunctions can be reduced by proper maintenance
  • Misuse can be avoided by insuring proper fit and
    by using correct donning procedures
  • Running out of air can be avoided by constant
    situational awareness

10
Respiratory Safety
  • Physical Stresses
  • Heart attack is still the NUMBER 1 killer of
    firefighters
  • Using SCBA increases cardiovascular work and heat
    stress
  • Sign and symptoms
  • Shortness of breath
  • Extreme fatigue
  • Chest pain
  • Light headedness
  • Confusion
  • Prevention
  • Keep hydrated
  • Keep physically fit
  • Rehab frequently
  • Know your limitations (work rate consumption)
  • Quit before there is a problem

11
Pack Familiarization
  • Manual on share drive
  • Packs on each table

12
Pack Familiarization
  • Cylinder valve
  • Purge valve
  • Straps
  • Low air alarms - Vibra-Alert _at_ 1000 psi

13
Pack Familiarization
  • HUD display
  • FULL cylinder - two green lights glowing near the
    center of the display.
  • THREE-QUARTERS cylinder - single green light
    glowing.
  • ONE-HALF cylinder - yellow light flashing slowly
    at one second.
  • ONE-QUARTER - red light at the far left flashing
    rapidly.
  • LOW BATTERY indicator at the far right of the
    display will light for twenty seconds and then
    begin to flash slowly at once a second. LOW
    BATTERY indicator is circular.

14
Pack Familiarization
  • Hansen (Low Pressure) Connection
  • AKA Shoulder Connection
  • Used receive air from hip hose (if access to hip
    hose for receiving air is not available).

15
Pack Familiarization
  • EBSS (Emergency Breathing Support System)
  • Low Pressure Connection
  • AKA Hip hose connection
  • Used to supply or receive emergency air

16
Pack Familiarization
  • Universal RIT Connection
  • High Pressure
  • Used to receive air from RIT pack

17
Pack Familiarization
  • RIT Pack
  • One hour bottle
  • Mask with regulator
  • Multiple low pressure Hansen Connections
  • High Pressure Universal RIT Connection

18
Inspections
  • SCBA Resource Manual
  • Contains all the information about our
    respiratory protection program
  • One is located at each station

19
Inspections
  • Daily, Weekly, Monthly After Use
  • Instructions located in resource manual
    apparatus binders
  • Daily and weekly inspections are documented on
    the apparatus inspection forms
  • Monthly and after use/in service inspections are
    documented on a separate form located in the
    apparatus inspection binders
  • It is imperative to perform and document monthly,
    after use/in service inspections. Failure to do
    so may lead to injury, death and/or heavy fines.

20
DEMONSTRATION
  • Daily
  • Weekly
  • Monthly, After Use/In Service

21
Cleaning
  • Use a mild liquid soap to clean both SCBAs and
    masks
  • Use multi-wash for disinfecting purposes
  • These items are conveniently located in a caddy
    beneath the sink in the SCBA room, along with 3
    buckets for mask washing

22
Maintenance
  • SCBAs
  • Maintenance is covered in scheduled checks and by
    having each pack bench tested every two years
  • Masks
  • Each member is responsible for inspecting and
    maintaining his or her own mask
  • Regularly inspect the face seal and lens for
    cracks or holes and inspect the retainer screws
    for tightness. Assure that all pieces are present
    and functioning properly.

23
Repairs
  • Operator repairs should be limited to the
    following
  • Replacing the nipple seal gasket
  • Replacing regulator gasket
  • Regulator tear down for disinfection purposes
  • All others should be tagged O.O.S. for a field
    level maintenance technician

24
Out of Service (O.O.S.) Equipment
  • OOS Tags Should contain the following
  • Name
  • Date
  • Description of the problem
  • Utilize available diagrams located in the SCBA
    room to properly identify O.O.S. parts whenever
    possible
  • Attach an O.O.S. tag to the appropriate part
    whenever possible
  • Always store O.O.S. equipment separate from
    in-service equipment

    necessary prior to each use
  • Perform the following on the weekly checks
  • Allow the compressor to run approx. 25 minutes by

  • After closing the drain, allow the compressor to
    fill and document the oil pressure and each stage
    pressure at completion
  • Document all of the above in the compressor log
