During preflight, how should you check for expirations on emergency equipment?

• A. Check only the oxygen mask.
• B. Review expiry tags and replace items past expiration date before flight.
• C. Rely on crew's memory.
• D. Assume equipment is valid unless visibly damaged.

Answer: (B)

Ensuring emergency equipment is within its expiration date is essential for reliability. The dates mark when the performance of devices like oxygen generators, masks, life vests, and other life-saving gear can no longer be guaranteed. During preflight, you review expiry tags or dates on every item and replace anything past its expiration before the flight departs. This guarantees that all life-saving equipment will function as intended in an emergency. If you find an expired item, swap it with a serviceable unit from stock or have maintenance replace it. Relying on memory or assuming an item is valid unless damaged can leave you with nonfunctional gear when it’s needed most.
