OXYGEN SYSTEMS - DESCRIPTION AND OPERATION
__________________________________________
1. General_______
A. The oxygen systems supply low pressure oxygen in gaseous form to the crew and passengers.
B. Two separate oxygen systems (Fig. 1) are included: the flight crew oxygen system and the passenger oxygen system. In addition, emergency oxygen is supplied by portable oxygen cylinder assemblies.
C. The flight crew oxygen system (Ref 35-12-00/001) has a supply of high pressure gaseous oxygen and distributes and delivers it at low pressure to the crew. High pressure oxygen is kept in an oxygen cylinder assembly. The oxygen cylinder assembly includes a safety discharge device to protect against too much pressure. Oxygen cylinder pressure is reduced through a pressure regulator. Low pressure oxygen is distributed through individual mask/regulator and mask stowage boxes.
D. The passenger oxygen system (Ref 35-22-00/001) automatically releases oxygen masks to the passengers and attendants whenever the cabin pressure falls to a value equivalent to an altitude of 14,000 feet. Oxygen is kept in chemical oxygen generators and oxygen flow is started by the action of the passenger or attendant pulling the oxygen mask down to the face. Mask deployment also can be operated by a switch on the P5 aft overhead panel.
E. The portable oxygen equipment includes portable oxygen cylinder assemblies and protective breathing equipment (when installed). The portable cylinders supply oxygen for emergency, first aid or sustaining oxygen for the passengers and/or crew. The smoke hood (PBE), emergency escape breathing device (EEBD) and the crew protective breathing equipment (CPBE) supply portable emergency respiratory and eye protection for the crew in an oxygen-deficient, smoke filled or other toxic atmosphere.
