Abstract
Abstract This apparatus is designed for automotive vehicles, and enables the employment of a vehicle's engine exhaust to be used to put out fires. Primarily, it consists of a flexible hose with a nozzle or cone at one end for the exhaust gas of the engine to be directed onto a fire, and the other end of the hose is secured to a selector valve attached to the tail pipe portion of the engine's exhaust system, so as to divert the exhaust gas for fire fighting. The apparatus includes a water spray collar at the rear of the nozzle which is supplied from a water source to cool the nozzle, and the nozzle includes a handle for a user to hold it.
