Electrical fires what type of extinguisher

Therefore, extinguishers with a B rating are designed to extinguish fires involving flammable and combustible liquids. Note: Do not attempt to extinguish a fire involving flammable gas unless there is reasonable assurance the source of fuel can be promptly shut off. In fact, if the only fuel burning is the leaking gas, the best method for extinguishing the fire is to shut off the fuel supply. Extinguishing a flammable gas fire, without shutting off the fuel, will allow unburned gas to escape into the atmosphere, which may permit a dangerous accumulation of gas to develop, and an explosion may occur if the gas is exposed to an ignition source.

Class C fires involve energized electrical equipment. Extinguishers with a C rating are designed for use with fires involving energized electrical equipment.

Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals.

Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase. The most common method for extinguishing a combustible metal fire is to cover the burning material with a dry powder, such as sand, which will not react with the material. However, it is always good to keep a class A fire extinguisher on hand or another type depending on what other flammable substances are around just in case the fire spreads to something else. Overall, the best way to prevent these electrical fires is to have a trained professional come in to complete electrical work when needed rather than doing it alone and without the proper information.

Other than that, regular inspections on objects requiring electricity to function as well as annual inspections on the fire extinguishers themselves are necessary. Oops, something went wrong.
