OXYGEN SERVICING
A 50-cu.ft oxygen cylinder is installed on the right side of the
cockpit/passenger cabin partition. This cylinder is designated for pilot,
copilot and observer use during emergencies. Its pressure can be
checked on the EICAS, inside the cockpit, and through an access
panel located on the right side of the aiplane nose. Minimum pressure
for dispatch of the main cylinder is:
−
Crew made up of pilot and copilot: 1100 psi
−
Crew made up of pilot, copilot and observer: 1500 psi
Portable oxygen cylinders are distributed along the cabin for
passenger and flight attendant emergencies. For airplane
dispatchability, the minimum pressure shown on the gauge of the
portable oxygen cylinder must be in accordance with the minimum
guideline set either for the airline or regulator authority.
Dispatching pressures were calculated for an ambient temperature of
21°C (70°F). For other temperatures, a correction chart is available at
the Operations Manual.
WARNING: HIGH-PRESSURE OXYGEN CAN CAUSE SUDDEN
COMBUSTION BY CONTACT WITH OIL, GREASE,
SOLVENTS, HYDROCARBONS IN GENERAL, CLOTH
FIBERS, METAL CHIPS, ETC. QUALIFIED
PERSONNEL ONLY MUST HANDLE AND SERVICE
THE OXYGEN EQUIPMENT.
