7.10 -- EMERGENCY OXYGEN SYSTEM
(Figure 7.10.1)
Emergency oxygen system must be used following a pressurization system
failure at an altitude between 12000 and 30000 ft. The three emergency
oxygen systems provide enough chemical oxygen for six persons during a
descent from 30000 to 12000 ft and below. These three systems, accessible
from central aisle, are located in a drawer under front passenger seat and
under the R.H. and L.H. intermediate seats for rear passengers.
Each system consists of two masks (equipped with microphone for front
places)
NOTE :
The pilot must imperatively use a mask equipped with a microphone.
A transparent flexible tube and a lanyard connect both masks to a generator.
When one of the lanyards is pulled, priming mechanism leads to a chemical
reaction inside the generator. When activated, the generator supplies
oxygen simultaneously to both corresponding masks for about 12 minutes
until it becomes empty.
NOTE :
It is not possible to interrupt flow during operation.
Each generator has two pressure relief valves which avoid an excessive
pressure in case of system malfunction or blocking in supply tube.
WARNING
SMOKING IS STRICTLY PROHIBITED ANY TIME OXYGEN IS IN USE.
OILY, FATTY OR GREASY SUBSTANCES, INCLUDING SOAPS,
LIPSTICK, AFTER SHAVE LOTION AND MAKE UP ARE CAPABLE OF
SPONTANEOUS COMBUSTION ON CONTACT WITH OXYGEN.
GENERATOR CHEMICAL REACTION LEADS TO A SENSITIVE
INCREASE OF ITS EXTERNAL TEMPERATURE, FOR THAT REASON
DO NOT OBSTRUCT ITS PROTECTIVE SHIELD.
