SAFA Ramp Inspections - Code7700

SAFA Ramp Inspection ProceduresGuidance materialInspection Item Inspections Item Title Inspecting InstructionsB09 Oxygen Supply Check if the PBE is at the indicated location and adequately marked with its operating instructions.Check cabin oxygen quantity (pressure gauge or electronic display) when stored oxygen is used.Check portable breathing equipment for serviceability and minimum number (against MEL).Check number / serviceability of oxygen dispensing units or oxygen masks (when possible).Note: if the oxygen masks and bottle fittings are not compatible, consider the oxygen mask as unserviceable.Note: inspectors should take into account that EU OPS 1.770 b.2(v) requires for aircraft not certified to operate above 25.000ft. to carry sufficient oxygen supply for 10% of the passengers, whereas ICAO requires this for all passengers. Alloperators should be treated equally, therefore the lower EU OPS requirements should apply.Note: Approximate altitude in the Standard Atmosphere corresponding to the value of absolute pressure used in this text is asfollows:Absolute pressureMetres FeethPa/ mBar mm Hg PSI700 700 525.043178 10.152642 3 000 10 000620 620 465.038243 8.99234 4 000 13 000376 376 282.023193 5.453419 7 600 25 000Inspection Item Std.
