When oil has been spilled, immediate
action shall be taken to remove
spillage from aircraft and adjacent
area. Clean rags may be used to
remove oil spillage from the aircraft.
Sand, dirt, sawdust, or commercial

Oxygen Servicing. Oxygen servicing requires the
utmost precautionary measures due to the highly
explosive and flammable capabilities of oxygen. Prior to
servicing an aircraft oxygen system, personnel shall
familiarize themselves with the system, precautions, and
instructions for handling gaseous oxygen, operation of
servicing equipment, and potential hazards involved.
Only qualified personnel shall be
authorized to operate equipment for
