For which item are the carry strap and mask attachment checked as part of its pre-flight procedure?

• A. Drager PBE
• B. Portable Oxygen
• C. Air liquide
• D. Drill Card

Answer: (B)

Portable oxygen equipment is designed for quick, hands-free deployment in an emergency. The pre-flight check focuses on making sure the unit can be worn and the mask can be attached securely, so oxygen can be delivered immediately if depressurization or smoke occurs. The carry strap must be intact so the bottle can be carried or secured to the wearer, and the mask attachment must be secure so the mask stays connected to the supply and seals properly when placed on the face. If either the strap is damaged or the mask connection is loose, oxygen delivery could be delayed or unreliable, which is why these checks are part of the portable oxygen procedure. Other items, like a PBE, are checked for different aspects (hood integrity, canister, activation), and don’t rely on a separate carry strap and mask attachment in the same way.
