harness: 
- If the batch number is found in the list of Appendix I, forward the defective inflatable harness 
to the appropriate Zodiac Services maintenanc e facility for replacement of the inflatable 
harness. 
B. Inflatable harness mounted on t he Crew Oxygen Mask Regulator : 
WARNING : STRICTLY OBEY THE PROCEDURES WHEN  YOU DO WORK ON OXYGEN SYSTEM. 
DO NOT USE OIL, GREASE OR OTHER LUBR ICANTS MADE FROM PETROL IN THE 
AREA OF OXYGEN EQUIPMENT. YOU CAN CAUSE A FIRE OR EXPLOSION. 
CAUTION :  APPLY THIS SB ON CLEAN SURFACE AND WITH CLEAN HANDS. 
Prior to using the flow chart to start the on-aircraft action(s), the operator, if he has the possibility, can 
determine, (e.g. aircraft maintenance logs check)  whether the inflatable harness has been replaced, 
during a maintenance operation, on an oxygen mask regulator installed on the aircraft.
