Abstract
A firearm for extinguishing a fire from a position remote from the fire. A cartridge is disposed in, and is selectively discharged from, a pistol. The cartridge includes a head containing a pressurized fire extinguishant and a casing containing a propellent. The casing is removably attached to the head by mating portions of hook and loop fasteners so as to allow the casing and the head to be independent of each other prior to use. The bead has a lip containing a chamber communicating with the pressurized fire extinguishant therein and which exits through through bores in both sides of the lip, respectively. A release pin is removed from the through bores and the firing apparatus is activated causing the cartridge to exit the barrel and expel the pressurized fire extinguishant through the through bores on its way to the fire during use.
