A طفايات حريق is a quick
fire protection device wont to extinguish or control small fires, often in
emergencies. It's not intended to be used on an out-of-control fire, like the
one which has reached the ceiling, puts the user in danger (i.e., no escape
route, explosion hazard, smoke, etc.), or otherwise requires the expertise of a
fireplace brigade. Typically, a fireplace place extinguisher consists of a
hand-held cylindrical pressure vessel containing an agent which will be
discharged to extinguish a fire.
طفايات حريق manufactured with non-circular pressure vessels also exist but are rare.There are two primary sorts of fire extinguishers: stored-pressure and operated by the cartridge. Stored in pressure units, the expellant is stored within the same chamber because of the fire fighting agent itself. Counting on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is usually used; water and foam extinguishers typically use air. Stored pressure fire extinguishers are the first common type. Cartridge-operated extinguishers contain the expellant gas during a separate cartridge that's punctured before discharge, exposing the fuel to the extinguishing agent.
Fire-fighting equipment also includes fixed fire-extinguishing and fire-alarm systems, fire extinguishers, fire hydrants, and other means for conveying extinguishing agents to the scene of a fireplace.This sort isn't as common, used primarily in areas like industrial facilities, where they receive higher-than-average use. They need the advantage of straightforward and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the hearth during a reasonable amount of your time.
Unlike stored pressure types, these fire extinguishers use compressed CO2 rather than nitrogen, although nitrogen cartridges are used on coldness (-60 rated) models. Cartridge operated extinguishers are available in chemical and powder types within the U.S. and water, wetter, foam, dry chemical (classes ABC and B.C.), and dry powder (class D) types within the remainder of the planet. Technical fire fighting equipment designed to rescue people and protect valuable goods and natural resources from fire. The essential apparatus are fire trucks, fire-fighting aeroplanes, fireboats, and fire-fighting trains and helicopters.
