Inspecting the SCBA and Facepiece

• SCBA must be properly serviced and prepared for the next use each time it is used.

• Air cylinder must be changed or refilled.• Face piece and regulator must be sanitized

according to the manufacturer’s instructions.• Unit must be cleaned, inspected, and checked for

proper operation.

• It is the user’s responsibility to ensure that the SCBA is in ready condition before it is returned to the fire apparatus.

• The daily inspection procedure should be used when restoring a unit to service after it has been used.

• If an SCBA inspection reveals any problems that cannot be remedied by routine maintenance, the SCBA must be removed from service for repair.

• Only properly trained and certified personnel are authorized to repair SCBA.

• Daily Inspection– Each SCBA unit should be inspected daily or at the

beginning of each shift.

Emergency Procedures

• If at anytime you have a problem with the operation of your SCBA, call “Mayday” over the radio and follow the Mayday Procedures.

• Addressing situations– Regulator Failure– Facepiece Failure– Out of Air– How to Air Conservation– How to use the EBSS– How to activate the PASS

• Regulator Failure– Occurs when the regulator will not deliver air to the

facepiece during normal operations.

• Regulator Failure– Procedure for using the Purge Valve

• Call “Mayday” and follow the Mayday Procedures.• Slowly open and close the purge valve to allow air flow to

the facepiece.

Purge Valve

• Facepiece Failure– This can occur when the facepiece cracks or breaks,

where you loose the seal, during operations that allows continuous airflow out of the mask.

– This will waste the air in your SCBA.

• Facepiece Failure– Procedure for Facepiece Failure

• Call “Mayday” and follow the Mayday Procedures.• Attempt to cover the possible crack or break in the facepiece.• Reset the Air Saver Switch or the Don/Doff Switch to stop the air

rushing out of the mask.• If needed, use the Purge Valve.

• Out of Air– Your first indication of low air is your Viberalert Alarm. It

alarms at 1125 psi or 25% of air left in the cylinder. You still have 2 to 5 minutes of air left.

Do Not Panic!Never Rip Your Facepiece Off!

• Out of Air– Procedure for Out of Air

• Call “Mayday” and follow the Mayday Procedures.• If you run out of air, you have two options.

1. Use buddy breath connection (EBSS) with your partner and get out.

2. Just Pull the mask slightly off your face to relieve the collapsing face piece and get out!» Get as low to the ground as possible so you can

breath and the hood that is surrounding the face piece will filter the smoke that you breath in.

• Conserving Air– During emergency operations, you will be using the air

in your SCBA. When you use about 75% (1/4 tank or about 1125 psi) of your air supply, your regulator will start vibrating to notify you your air supply is getting low.

– When this happens, you will need to start evacuating yourself/team out of the area.

• Conserving Air– Procedures

• Reset the Air Saver Switch or the Don/Doff Switch

• Call “Mayday” and follow the Mayday Procedures.• Slowly open and close the purge valve to allow air flow to

the facepiece.• Take a deep breath of air and hold your breath for 5 seconds.

Repeat the process until you are out of the building/IDLH environment.

• Emergency Breathing Support System (EBSS)– SCBA’s are equipped with the EBSS. It is located next to the

remote gauge/PASS device.– If you are working during an incident and you find a firefighter

down and the SCBA is empty, you can quickly connect their regulator to your SCBA. It basically allows two people to use the air off of one pack at the same time for emergency evacuation purposes only.

– Procedure for Using the EBSS

• Both fire fighters shall be in close proximity.

• Unsnap the EBSS airline Hold Down Strap and remove the dust cap.

– Procedure for Using the EBSS

• Disconnect the low-pressure regulator hose at the quick-connect of the empty pack and quickly re-connect it to the pack with air. The HUD will not work on the 2nd fire fighter, it does not have a HUD connector on the EBSS line.

– Procedure for Using the EBSS• Coordinate movements, there is only a few feet of hose, as

you evacuate yourselves from the building/IDLH environment.

• Personal Alert Safety System (PASS)– An electronic device that sounds a loud audible signal

if a fire fighter is motionless for a set time period or if activated manually by the fire fighter.
