Which action should be performed to verify readiness before donning the SCBA?

• A. Turn on the SCBA unit
• B. Test the low air alarm
• C. Check the air pressure of the SCBA unit
• D. Verify harness fit

Answer: (C)

Verifying the air supply before donning the SCBA is essential. Checking the cylinder pressure confirms the tank is charged and has enough breathable air for the planned work, and helps catch a cylinder that’s empty or leaking before you commit to entering a hazardous area. If the pressure is below the department’s minimum, you don’t proceed until it’s recharged. The other steps are important parts of a complete pre-use check—turning the unit on and testing the low-air alarm ensure the system is functioning and will alert you to low air, while verifying harness fit ensures the pack sits securely and comfortably. But without confirming the actual air pressure, you can’t safely begin the task.
