The construction, inspection and maintenance of an airplane may involve confined space entry.
Hazards:
(1) jet fuel
(2) other fluids (hydraulic, other)
(3) electrical current
(4) cleaning and maintenance fluids
(5) sloping walls and floors
(6) fire
(7) sharp edges
(8) temperature extremes
Entry into a fuel tank is particularly hazardous since the fuel may have vaporized and oxygen may be depleted.
A person making the confined space entry should be in communication with the outside monitoring who can initiate rescue if a problem arises.
