Avoid Tyre Explosion Hazard
Whenever a machine’s tyre(s) is (are) exposed to excessive heat
such as a machine fire or extremely hot brakes, the hazard of a
subsequent violent tyre explosion must be recognized. All nearby
persons must avoid approaching the machine so as not to be
physically endangered in the event of an explosion of the tyre
and rim parts. The machine should be moved to a remote area,
but only when this can be done with complete safety of the oper-
ator operating or towing the machine. All other persons should
stay clear of the machine. 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 machine by use of
hand-held fire extinguishers. If it is absolutely necessary to
approach a machine 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 (1500 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
machine is shut down or the fire extinguished before approach-
ing closer.
