Which option accurately describes a complete pre-use facepiece seal integrity verification?

• A. Visual Inspection, Functional Checks, and a Facepiece Seal Fit Check
• B. Visual Inspection Only
• C. Functional Checks Only
• D. No Checks Required

Answer: (A)

A complete pre-use facepiece seal integrity verification combines three essential checks: a visual inspection, functional checks, and a facepiece seal fit check. Each part targets a different potential failure mode, and together they ensure the mask is safe to wear. Visual inspection looks for damage or wear on the facepiece and its components—cracks, tears, torn or stretched straps, damaged buckles, a compromised exhalation valve, dirty lenses, or other defects. If any of these are present, the seal and overall integrity can be compromised, even if the rest of the system is functioning. Functional checks verify that the SCBA system operates correctly beyond the mask itself. This includes confirming the regulator provides the correct airflow, alarms function, hoses and connections are leak-free, and the overall system maintains pressure as intended. A problem here could undermine air delivery or mask performance even if the mask appears intact. The facepiece seal fit check ensures the mask actually seals against the wearer’s face. Donning the mask and performing a seal check (positive pressure and/or negative pressure) reveals whether air leaks around the seal when breathing normally. A good seal depends on facial features, proper donning, and the integrity of the seal frame and straps; without this check, leaks could go unnoticed. Putting these together—look for damage, confirm the system’s functionality, and verify the mask seals properly when worn—provides a complete verification of pre-use facepiece seal integrity. Skipping any part could allow a leak or malfunction to go undetected.
