-- Oxygen masks fall and hang on the lanyards.
-- User pulls one mask to their face. (The lanyard pulls the release pin from the
striker assembly of the generator).
-- The striker hits the percussion cap, and the oxygen supply is generated.
-- Oxygen flows through the flexible supply hoses into the reservoir bag.
-- The flow indicator indicates oxygen flow as follows : in case oxygen is flowing
> 0,5 lpm in the housing of the flow indicator, a green tube is visible. If there
is no oxygen flowing or < 0,5 lpm, there is noting visible inside the clear flow
indicator housing.
-- The chemical oxygen generator supplies a flow of low pressure oxygen for a
minimum of 15 minutes.
CAUTION
ONCE ACTIVATED, OXYGEN GENERATION CANNOT BE STOPPED.
-- The chemical reaction used for oxygen generation creates heat. Therefore,
after an emergency mask deployment, it is recommended that a PAX
announcement be made to advise of the possibility of the smell of burning,
smoke, and of a cabin temperature increase associated with normal operation
of the oxygen generator system.
INADVERTENT OXYGEN MASK DEPLOYMENT
CAUTION
DO NOT RESTORE AN OXYGEN MASK, IF THE OXYGEN GENERATOR IS
STARTED IN ORDER TO PREVENT THE SMELL OF BURNING OR FUMES.
RECOMMENDATIONS
-- Although it is not dangerous to the aircraft, if the oxygen mask is stored when
the oxygen generator started, this occurrence may be very unpleasant and
frightening for passengers and crew. Both the flight and cabin crewmembers
