Avoid Tyre Explosion Hazard AT LEAST 460 m (1 500 ft) AT LEAST 15 m (50 ft) WARNING Whenever a vehicle’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 vehicle so as not to be physically endangered 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 machine is shut down or the fire extinguished before approaching closer. 172 2-15
