What actions should you take if you detect a leak around the mask seal during a seal check?

• A. Re-seat the mask, adjust straps evenly, and retest; if the leak persists, replace the mask or stop the operation
• B. Ignore the leak and continue
• C. Remove the mask entirely and keep working
• D. Increase the cylinder pressure to compensate

Answer: (A)

When a leak appears around the mask seal during a seal check, the priority is to establish a tight, uniform face seal. Re-seat the mask, adjust the straps evenly to apply even pressure around the gasket, and retest to verify the seal. If the leak persists, the mask isn’t providing the required protection, so replace the mask or stop the operation to avoid exposure. This approach stops unsafe breathing of contaminated air and prevents overreliance on cylinder pressure to compensate for a faulty seal. Ignoring the leak, removing the mask, or trying to compensate with more cylinder pressure would all fail to address the real issue and could create danger.
