Which action correctly describes manually deploying the oxygen mask?

• A. Use a paper clip through the hole
• B. Pull the mask by the strap
• C. Wait for automatic deployment
• D. Use a paper clip to depress a hidden release

Answer: (D)

Manual deployment hinges on activating a concealed release that starts the oxygen flow. When the automatic system can’t or hasn’t deployed, you need to engage the hidden release to unlock the oxygen path and begin delivering oxygen to the mask. This direct action is what ensures immediate oxygen delivery rather than waiting for a mechanical sequence to happen on its own. Using an improvised tool like a paper clip is unsafe and not part of proper procedure, and simply pulling the mask may not activate the oxygen supply if the release mechanism isn’t engaged. Waiting for automatic deployment delays response, which isn’t appropriate in an emergency.
