Will the FMCSR-required extinguisher extinguish a tire? a No. ‘The extinguisher may briefly control the surface flames, but after the extinguisher has been emptied, the tire 1s likely to re-flash because of the heat built up deep inside the tire carcass. Q. What precautions can a driver take to minimize the risk of electrical fire? To minimize the risk of electrical fires, a professional driver should: 1. Be sure the battery 1s properly secured. 2. Look for worn, deteriorated or charred insulation on wiring. Report any such condition to the maintenance shop. 3. Not bypass or interfere with the normal functioning of fuses and circuit breakers. 4. Not install personal electrical equipment such as CB radios, CD players, recorders, etc., except in accordance with company policy. In the event of an electrical fire, what must be done besides attempting to comtrol the flames? The battery must be disconnected, if safe to do so. If it isn't, then the battery will continue to heat up the wiring and diminish the ability to successfully control or extinguish the fire. When might disconnecting the battery not be enough to control an electrical fire? In a severe crash, the vehicle's metal parts might penetrate the battery and allow a flow of current even after the battery cables have been disconnected. ‘This can permit the development of sufficient heat to cause a fire. At the scene of an accident, what checks should be made to minimize the risk of fire? To minimize the risk of fire at an accident, the professional driver should check to ensure that: 1. The engines of all damaged vehicles are turned off. 2. There is no leaking fuel. 3. No one is smoking in the vicinity, especially if there is leaking fuel. 4. If there is evidence of leaking fuel, then fusees should not be used to direct traffic or protect the scene. 1G
