For PBE pre-flight, which of the following is checked to ensure integrity?

• A. Two seals intact
• B. One seal intact
• C. No seals present
• D. Seal is blue

Answer: (A)

Two seals intact are checked because the PBE uses two independent tamper seals to prove the unit hasn’t been opened since its last inspection. When both seals are unbroken, you can trust the packaging and contents are still in their guaranteed, ready-to-use condition. If a seal is broken or missing, the integrity isn’t guaranteed and the PBE is considered not serviceable until maintenance checks are completed. The color of a seal isn’t the criterion for this check.
