What action is described first when using oxygen with mask retainers and streamers on the CRJ 700?

• A. Pull the streamer firmly downward
• B. Remove the mask from the retainer
• C. Open the oxygen panel
• D. Push the streamer upward

Answer: (A)

When deploying oxygen masks that use retainers and streamers on the CRJ 700, the first action is to pull the streamer downward to release the mask from its retainer. The streamer is designed to unlock the mask from its stowed position; pulling it downward frees the mask so you can grasp it and place it over your face. Pushing the streamer upward wouldn’t unlock the mechanism, and opening the oxygen panel isn’t the immediate first step because the mask is already in position to be released when you pull the streamer. Removing the mask from the retainer comes after the release action, once the mask is free to be put on.
