For fire engines, the terminal insulation caps of the engine block heater (an electric heater that heats the engine to ease starting in cold weather) do not have sufficient heat resistance, and therefore, they may deteriorate in condition, when the heater is repeatedly used at length for a long period of time. If the insulation capability is reduced and a snow-melting agent etc. seeps into the terminals, corrosion may occur. If this problem is left unattended, the contact resistance may increase and the terminals may generate some heat. The results of this can be a wire disconnection or a burn out of the terminals, which in the worst case could result in a fire.
