    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.
