BCD FLIGHT CREW OXYGEN MASK USAGE
Donning Instructions
To don the oxygen mask accomplish the following:
- Grasp the regulator by the red inflation levers with the hand nearest the
stowage box.
· Squeeze the inflation levers while pulling the mask from the box.
· Pull the mask across in front of you, toward the center of the aircraft (to
ensure ample hose extension) while rolling the mask face-up.
· Lean slightly toward the center of the aircraft and bring the mask toward
your face so that the lower portion of the mask contacts your chin first. Roll
the top of the mask toward your forehead so the harness goes over and
behind your head.
· Release the inflation levers so the harness holds the mask in place.

Stowing Instructions
To stow the oxygen mask accomplish the following:
· Set the N / 100% regulator control to 100%.
· Ensure that the EMERGENCY oxygen control knob is off.
· Coil the supply hose into the bottom of the stowage box, making the largest
diameter possible.
· Ensure that the harness is completely deflated.
· Hold the mask by the regulator, with the facepiece down and the inside of
the mask toward you.
· Grasp the harness and pull it downward so the cross straps are below the
facepiece. Allow the excess harness to hang downward.
Caution: Do not push the harness cross straps into or behind the nosepiece.
Doing this may cause the cross straps to hang up on the mask
during inflation.
· Position the supply hose down the center of the facepiece.
· Insert the mask-regulator assembly into the stowage box, beginning with
the harness (regulator up).
· Press down on the assembly until the mask-regulator is fully seated against
the stop in the stowage box.
· Close the left-hand door. The OXY ON flag will slide into view at the center
of the door.
· Close the right-hand door, ensuring not to pinch the hose.
· Press, then release the TEST AND RESET control lever on the left-hand door.
Ensure that the OXY ON flag disappears when the control lever is released.
WARNING: Do not squeeze the red inflation levers during stowing.
Doing this will inflate the harness and prevent the correct
stowing of the mask.
