Study Notes

SCBA Operations and Maintenance

PASS (Personal Alert Safety System) will flash and emit audible alarms.
Ensure pressure gauge needle is in the green (FULL) zone before use.
Facepiece must be donned, and seal and exhalation valve checks performed.
Attach second stage regulator to the facepiece; first breath activation should create positive pressure without excessive free flow.
Check the Heads-Up Display (HUD) for full cylinder pressure, indicated by all four green LEDs lit.
Close air cylinder valve; monitor pressure gauge for 20 seconds for any drop indicating leaks.
A drop in PSI may signal a malfunction requiring repairs to the "O" ring at the regulator/cylinder connection.
Open the bypass valve slowly; observe for the warbling whistle alarm activation between 1035 to 1215 PSI.
The audible alarm sounds until pressure drops below 200 PSI.

Cleaning Procedures

Use warm water and mild detergent to create a cleaning solution for the facepiece.
Immerse the facepiece in the solution and gently clean with a soft brush.
Ensure all parts, particularly the lens and regulator connection, are cleaned thoroughly and free of contaminants.
Inspect facepiece for tears, proper function, and ensure it has no leaks or sticking valves.
Low and high-pressure hoses must be checked for integrity and function.
Examine the exterior of the compressed air cylinder for any damage; evacuate and test if found defective.
Replace the air cylinder if the gauge reads below 4000 PSI on the digital pressure gauge.
Backpack components should be checked for fraying, corroded buckles, and overall functionality.
Battery status indicators for PASS and HUD should be checked; an LED flash every 10 seconds indicates full battery, while every 2 seconds indicates low battery.

Emergency Breathing Procedures

"Buddy Breathing" allows an out-of-air member to share a breathing supply with a donor.
The out-of-air member retrieves the buddy breathing hose from their left hip pouch.
Proper connection to the donor's buddy breathing "Y" block is essential; practice with gloved hands ensures proficiency.
The donor must lead both individuals to safety immediately after initiating the connection.

Inspection and Maintenance Requirements

SCBA must be inspected daily and after each use for defects or damage.
Focus on careful maintenance, cleaning, storage, and transportation to prevent foreign matter-related damage.
Repairs limited to battery and "O" ring replacements are permissible; all other repairs must be handled by certified personnel.
Inspect facepiece skirt and headstrap for tears, pliability, and overall condition to ensure safety and functionality.
