What is a Fire Extinguisher?
Types of Extinguisher
Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured before discharge, exposing the propellant to the extinguishing agent. This type is not as common and is used primarily in areas such as industrial facilities, where they receive higher-than-average use. They have the advantage of simple and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the fire in a reasonable amount of time.
Unlike stored pressure extinguishers, cartridge-operated extinguishers use compressed carbon dioxide instead of nitrogen, although nitrogen cartridges are used on low-temperature models. Cartridge-operated extinguishers are available in various types, including:
- Wetting Agent
- Dry Chemical
- Dry Powder
