AVOIDANCE OF FIRE HAZARD -- FUELLING NEAR JET AIRCRAFT
In order to avoid discomfort to personnel and risk to fuelling operations, the following steps should be taken by all concerned :-
- With turbo-jet aircraft there is a zone to the rear of the jet outlets in which there is a risk of injuring personnel or of igniting petroleum vapours by the blast of hot gases from the engines. To guard against these hazards it is necessary to enforce special safety distances within which the movement of personnel or the operation of fuelling equipment is forbidden.
- For all known existing and projected jet engines, the minimum safety distances to be enforced, measured from behind the jet outlet, are as follows :
(a) To avoid discomfort to personnel 37 M
(b) To avoid risk to fuelling operations 43 M
- If during the course of fuelling operations, a turbo-jet aircraft manoeuvres into a position in which the jet blast is liable to come within 61 M of the operating fuelling equipment, fuelling should be stopped at once, the caps of the aircraft fuel tanks closed down, and if necessary the fuelling outfit removed to a safe distance.
These precautions do not apply to turbo-prop aircraft which can be treated in the same was as piston-engined aircraft.
