Portable Protective Breathing Equipment
Protective Breathing Equipment (PBE/Smoke Hood) devices for crew use (for
combating fires and/or entering areas of smoke or fume accumulation) may be
stowed throughout the airplane; however, they are normally found in the forward
and aft sections of the passenger cabin. The device is placed over the head and,
when activated, provides approximately 15 to over 20 minutes of oxygen
depending upon the device used. Manufacturer’s operating instructions are
placarded on the container.
Passenger Oxygen System
The passenger oxygen system is supplied by an individual oxygen source located
at each Passenger Service Unit (PSU). Four continuous flow masks are connected
to each source. An oxygen source with two masks is located above each attendant
station and in each lavatory.
