Automotive engine heater knowledge helps prevent fires Published Jan. 11, 2010 By Brett Galeener Buckley Fire Department BUCKLEY AIR FORCE BASE, Colo. -- Checking vehicle engine heater units periodically can extend the life of the unit as well as preventing vehicle fires. To ensure the units are functioning properly, follow this advice: - Ensure electrical connections and extensions are in good repair, are the proper size, and are weatherproof. - Extreme temperatures may cause the insulation to crack when handled or coiled. A fire hazard exists should wiring become exposed. - Do not run extension cords or wiring through or under doors, through windows, or other means from inside your house or work center. Use only exterior receptacles designed for this purpose. - Do not secure electrical extensions with nails or wire. This may cause the extensions to become frayed or worn. Use only authorized insulated staples for stationary extensions. - Engine battery, dip sticks and tank heater units can be just as dangerous as they are useful. Proper installation is a must to prevent costly fires. Take the necessary precautions now to assure a safe operation or pay the consequences later.
