Activating the system causes the masks to drop from their dispensing
units. Each oxygen generator is activated when any mask in the
associated dispensing unit is released. Pulling one mask down causes
all masks in that unit to drop and 100% oxygen flows to all masks.
Oxygen flows for approximately 12 minutes. Once oxygen flow was
started, there is no way to stop it.
CAUTION: ONCE ACTUATED, EACH CHEMICAL GENERATOR
SUPPLIES OXYGEN CONTINUOUSLY, WHETHER THE
MASKS CONNECTED TO IT ARE BEING USED OR NOT.
NOTE: When oxygen is supplied, high temperature is produced in the
oxygen chemical generator.
An in-line flow indicator is visible in the transparent oxygen hose
whenever oxygen is flowing to the mask.
If the system is activated and the door of a dispensing unit does not
open, the attendant may drop the masks through a door-opening tool.
This tool is located near the cabin attendant stations.
A portable oxygen cylinder and a Protective Breathing Equipment
(PBE) unit are installed near each cabin attendant station.
