B777 EMERGENCY EQUIPMENT 8.80.1 Oxygen 10 NOV 16FLIGHT ATTENDANT MANUALOxygen SystemsTwo independent oxygen systems are provided: one for the flight deck andone for the passengers and flight attendants.The oxygen system consists of:  A cockpit fixed oxygen system  A cabin fixed oxygen system  A portable oxygen systemEmergency Oxygen –Passenger and Flight Attendant Passenger CabinThe passenger oxygen system is supplied by chemical oxygen generators.Oxygen masks are contained in the oxygen stowage box located inlavatory ceilings, crew rest bunks, and in the passenger service unit (PSU)above the passenger seat. One mask is supplied for each passenger seatand two for each lavatory. Pulling on the mask turns on the flow of oxygento all masks contained in the PSU.Oxygen is available for approximately 22 minutes.Masks automatically drop from stowage and a continuous flow of oxygen isinitiated when a mask is pulled. Pulling on the mask causes oxygen flow.The system activates automatically if cabin altitude exceeds approximately13,500 feet. If a group of masks fails to drop, the oxygen maskcompartment may be opened manually.Note: If the masks fail to drop from a PSU, the cover of the oxygen compartment can be opened manually by releasing the door latch. The latch can be opened by inserting a hair pin or a thin rod into the hole of the compartment cover.The system may be manually activated by the flight crew at any altitude bypushing the passenger oxygen switch on the flight deck.WARNING: the oxygen generator surface temperature may reach 260°C when generating oxygen. Don’t touch or attempt to remove generator. Burn injury can result. If an active generator is inadvertently removed from compartment, it must be placed in a metal container such as lavatoror galley sink. Heat will scorch other materials or fabrics.

B777 EMERGENCY EQUIPMENT 8.80.2 Oxygen 10 NOV 16FLIGHT ATTENDANT MANUALFlight Attendant OxygenDue to the height of the ceiling in the airplane, flight attendants may not beable to reach the oxygen masks at their stations when in their seats withtheir seat belts and harnesses on. When the oxygen masks deploy, theflight attendants must pull on the yellow streamer that falls from the oxygenbox. The streamer has the word PULL stenciled onto it.Pulling the streamer allows the mask to drop and turns on the flow ofoxygen to the masks and provides oxygen to both masks.

B777 EMERGENCY EQUIPMENT 8.80.5 Oxygen 10 NOV 16FLIGHT ATTENDANT MANUALCabin Oxygen SystemOxygen flows from a PSU generator when any mask hanging from thatPSU is pulled.An Extra mask is provided for Double, Triple and Quadruple seat row,except for Double Seat 1DH in Magnifica Class that is provided with twoextra masks.The masks automatically drop from the PSUs if cabin altitude exceedsapproximately 13,500 feet. The passenger masks can be manuallydeployed from the flight deck by pushing the overhead panel PASSENGEROXYGEN switch to the ON position.Oxygen flows for approximately 22 min and cannot be shutoff.CAUTION: The oxygen generator surface temperature may reach 260 C° when generating oxygen. Do not touch or attempt to remove generator. Burn injury can result. If an active generator is inadvertently removed from compartment, it must be placed in a metal container such as a lavatory or galley sink. Heat will scorch other materials or fabrics.Note: Odour similar to scorched cloth may be created by activation of generators. The odour does not affect the purity of the oxygen and there is no fire hazard.

B777 EMERGENCY EQUIPMENT 8.80.12 Oxygen 10 NOV 16FLIGHT ATTENDANT MANUALDecompressionIf cabin altitude exceeds approximately 10,000 feet or the passengeroxygen system is manually deployed by the flight crew, the followingautomatic events take place: • cabin lights come on full bright • five HI chimes sound • NO SMOKING/FASTEN SEAT BELT signs illuminate and corresponding chimes sound • the DECOMPRESSION pop-up window appears on the cabin management system displays wherever one of these screens is displayed: • CABIN LIGHTING • ENTRY WAY & CROSS AISLE LIGHTSThese events warn the flight attendants that a possible decompression isabout to occur. Flight attendants must sit down, fasten their seat belts, andprepare to put oxygen masks on.Note: The oxygen masks automatically drop from the PSUs if cabin altitude exceeds approximately 13,500 feet. The oxygen masks may also be manually deployed from the flight deck.Note: Guidelines for decompression while occupying either the door 1 upper crew rest or the door 3 upper crew rest area are contained in Chapter 11, Crew Rest Non-Normal Situation Guidelines.
