List the key items to inspect during a pre-use SCBA check.

• A. Cylinder full/pressurized; facepiece integrity; straps and harness condition.
• B. Cylinder full/pressurized; seal integrity; and monitor readings only.
• C. Facepiece cleanliness and strap wear only.
• D. Gauges readable and alarms functional only.

Answer: (A)

The main idea is to verify three essential safety aspects before using an SCBA: air supply, equipment integrity, and a secure fit. The cylinder must be full or pressurized so you have enough breathing air for the anticipated work. The facepiece should be intact with no cracks, damage, or degraded seals that could let contaminated air in and prevent a proper seal to the face. Straps and the harness need to be in good condition so the unit stays securely on the wearer and doesn’t shift or come loose during activity. The other options fall short because they omit one or more of these critical elements: relying only on readings or alarms ignores the actual air supply and the integrity of the facepiece and harness; focusing on cleanliness or wear without confirming air and secure fit misses the core safety checks needed for a reliable, safe SCBA use.
