Which two types of tests are typically performed to ensure SCBA function before use?

• A. Visual Inspection and Functional Checks Including Regulator Purge and Air Flow Test Plus a Facepiece Seal Fit Check
• B. Visual Inspection Only
• C. Battery Check and GPS Check
• D. Thermal Imaging Check and Battery Test

Answer: (A)

Before using an SCBA, you need to confirm both its condition and its operation. Start with a visual inspection to look for obvious damage or wear: check the cylinder, hoses, regulators, valves, facepiece, straps, and the harness. Any cracks, leaks, or loose connections can render the unit unsafe. Then perform functional checks to make sure it actually delivers air properly. The regulator purge test ensures the regulator delivers air when opened, the air flow test confirms a steady, adequate flow without resistance or leaks, and the facepiece seal check verifies the mask seals tightly on the face so air doesn’t escape around it. This combination—visual inspection plus the regulator purge, air flow, and facepiece seal checks—covers both the physical integrity and the operational readiness of the SCBA. Other options add tests that aren’t relevant to typical pre-use SCBA checks.
