What should you do if you find a red seal on the PBE (Essex PBE)?

The correct action to take when you find a red seal on the PBE (Personal Breathing Equipment) is to notify the Captain and write a message to the flight crew. A red seal indicates that the equipment may have been tampered with or is not ready for use, which raises safety concerns.

In aviation safety protocols, communication with the Captain is crucial because they are responsible for the overall safety of the flight and can determine the next steps, which may include replacing the PBE or grounding the equipment until it is inspected. Writing a message ensures that all relevant crew members are informed of the issue, thus maintaining the safety and preparedness of the crew and passengers.

Continuing with the check or using the PBE without concern would not address the potential risk posed by the compromised seal, which could jeopardize safety in emergency situations. Replacing it immediately without notifying the Captain first may lead to miscommunication or improper procedures being followed. Hence, notifying the Captain and documenting the situation ensures that safety protocols are respected and followed appropriately.
