SFFMA Objectives
27-02.01 Trainee shall identify the procedure for daily inspections
and maintenance of self-contained breathing apparatus.
27-02.02 Trainee, given each type of self-contained breathing
apparatus, shall demonstrate the correct procedure for
recharging.
27-02.03 Trainee shall demonstrate the following emergency
techniques using self-contained breathing apparatus to:
A. assist other firefighters
B. conserve air
C. show restrictions in use of by-pass valves
D. breathing from the breathing tube or regulator in the event of a
face piece failure
27-02.04 Trainee shall demonstrate the procedure for cleaning
and sanitizing self-contained breathing apparatus for future use.
Parts of SCBA System
Air cylinder
Regulator
Backpack frame
Facepiece
PASS Alarm
Maintenance of the SCBA System
The five components of the system combine
to allow a firefighter to safely operate in a
dangerous environment.
Proper maintenance of all parts is required to
ensure the system does not fail.
Air Cylinder
Visual inspection of the cylinder, gauge, and
valve to check for damage, dents, cracks or
other anomalies.
Check the cylinder to ensure it has at least 4000
psi. If below, have the cylinder filled.
Prior to filling, check the hydrostatic test date to
ensure within limits. All cylinders we have must
be hydrostatically tested every three years.
Regulator
Takes the high pressure air of the cylinder,
and steps it down to a usable pressure.
1st stage or pressure reducer connected to
backpack frame, and is not serviceable by
field level technician.
2nd stage mounts to the face piece.
Regulator
High pressure and low pressure hoses can be
checked for nicks, cuts, or abrasions that could
cause failure. Check “O” ring at cylinder
connection.
Hose connections can be checked for air leaks.
Regulator
Leaking or damaged hoses or “O” rings can be
serviced by field level technician
Minor repairs can be done to regulator, ie:
replace gaskets, springs, diaphragm
Backpack Frame
Provides the mounting platform to hold the air
cylinder in place, and attachment for pressure
reducing and regulator assembly, and remote
pressure gauge.
Shoulder and waist straps allow the system to be
carried comfortably on the body
Two styles – wire frame model, and solid
aluminum frame contoured to wearers back
Backpack Frame
All straps should be checked for cuts or
abrasions that could result in failure
Heavily worn or damaged straps should be
replaced
Frame should be inspected for broken welds,
and worn or broken mounting hardware
Facepiece
Protects the wearer from exposure to heat, toxic
gases, and unburned products of combustion
Allows the wearer to see in a smoke filled
environment
In conjunction with the regulator, provides a
source of fresh air
Facepiece
Examine face piece for cracks or scratches that
could cause failure, especially around the
regulator mount
Check temple and neck straps for excessive
wear, or loss of elasticity. If worn, or no stretch in
them, have them replaced
Facepiece
Check skirt of mask to ensure no cuts or tears
that could cause failure
Check nose cup and inhalation check valves
Check voice amplifier for operation
After use, clean by spraying disinfectant on the
interior and wait at least 10 minutes before
wiping the mask dry
PASS Alarm
Audible warning device that signals for
assistance when a fire fighter goes down or
becomes incapacitated.
Should always be activated BEFORE entering an
IDLH environment.
Operation should be tested weekly and battery
replaced at regular interval.
Field Function Test of Air Pack
Ensure that the unit is clean – no loose debris,
system wiped down to clean off any debris or
unburned products of combustion
Turn on air cylinder – ensure pressure at cylinder
gauge and remote gauge is equal or fairly close
– if big difference tag and take out of service
Listen for activation of low air warning system
Field Function Test of Air Pack
Attach mask to regulator
Place mask on face and inhale to start air flow,
ensuring smooth air flow in system
Check purge valve to ensure proper operation
Turn off air cylinder and bleed down system –
listen for activation of low air warning system
Activate donning switch
Field Function Test of Air Pack
Extend all straps.
Check PASS alarm for proper function.
Extend straps on face piece.
Check voice amplifier for operation.
Bag face piece to keep it clean and dust free.
Log inspection in the SCBA log book.
Fill Station
Instructor will teach/demonstrate how to fill SCBA
Bottles from:
Station 1 Fill Station
Rescue 81
Instructor will teach/demonstrate how to fill storage
bottles on Rescue 81
Cleaning / Sanitizing
Procedures for cleaning/sanitizing face masks after
use:
Mask will be washed under clean water to remove excess
debris
Mask sanitizer wipes will be used on all rubber portions
of the mask
Face shield will be wiped with alcohol wipe
Mask will be dried and placed back on apparatus
Practical Exercise
Firefighter shall:
Demonstrate the following emergency techniques using
the SCBA to:
Assist other firefighters with turning on and off SCBA
Conserve Air
Skip breathing, etc…
Show restrictions in use of by-pass valve
Breathing from the breather tube or regulator in the event of a
face piece failure
