What is the second step in the OPERATION - PBE sequence?

• A. Tear off red pull strip
• B. Open storage case
• C. Remove device from protective bag
• D. Pull off "pull to actuate" ring to start the flow of oxygen

Answer: (A)

The action being tested is the order of activating a protective breathing equipment unit. After you’ve opened the storage case to access the PBE, the next deliberate step is to tear off the red pull strip. This red strip is a protective seal that must be removed to begin preparing the device for use; tearing it immediately primes the unit and prevents accidental activation while it’s still in the case. Once that strip is removed, you proceed with removing the device from its protective bag and then finally start the oxygen flow by pulling the actuate ring. The tear strip being the second step keeps the sequence efficient and safe, moving quickly from access to readiness so activation can happen without delay when needed.
