AVOID TYRE EXPLOSION HAZARD
Whenever a vehicle’s tyre(s) is (are) exposed to excessive heat, such
as a vehicle fire or extremely hot brakes, the hazard of a subsequent
violent tyre explosion must be recognized. All nearby persons must
avoid approaching the vehicle, so as not to be physically endan-
gered in the event of an explosion of the tyre and rim parts. The
vehicle should be moved to a remote area, but only when this can
be done with complete safety of the operator operating or towing
the vehicle. All other persons should stay clear of the vehicle. The
fire or
overheated brakes, wheel, etc., should be extinguished or cooled
from a safe distance. Do not attempt to extinguish the fire or cool the
vehicle by use of hand-held fire extinguishers. If it is absolutely
necessary to approach a vehicle with a suspect tyre, approach only
from the front or the back. Stay at least 15 m (50 ft) from the tread
area. Keep observers out of the area and at least 460 m (1 500 ft) from
the tyre sidewall. Refer to the accompanying sketch. The tyre(s) should
be allowed at least eight (8) hours cooling time after the vehicle is
shut down or the fire extinguished before approaching closer.
