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

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

Answer: (A)

Opening the storage case is the first step because the PBE is stored in a sealed container for protection, and you must access the unit before you can perform any other actions. If you don’t open the case, you can’t tear the red pull strip, remove the device from its protective bag, or initiate the oxygen flow. Once the case is opened, you tear away the red strip to unlock and expose the PBE, remove it from the protective bag, and then pull the “pull to actuate” ring to start the oxygen flow and begin donning the hood.
