Abstract
A fire extinguisher includes a tank and a gas generator breech connected to the tank. The gas generator breech is provided with a hermetically sealed gas generator cartridge. The hermetically sealed gas generator cartridge avoids the need to have a release poppet or burst shims on the gas generator breech. The enclosed space that contains combustion gas pressure is provided by the gas generator cartridge itself and not the gas generator breech. The gas generator cartridge is made from a container that can be the precursor to a beverage can used for carbonated beverages. The beverage can may come in a thickness and material of construction that makes it a suitable, cost-effective container for the gas generator cartridge. However, other containers besides precursors of beverage cans can be used.
