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.
