Which extinguisher is used for flammable liquids as well as electrical fires?

The black carbon dioxide extinguisher is specifically designed to tackle both flammable liquid fires and electrical fires effectively. Carbon dioxide extinguishers work by displacing oxygen in the fire area, which is crucial for extinguishing flames. This type of extinguisher does not leave any residue, making it ideal for use on electrical fires where equipment damage is a concern.

Its effectiveness against flammable liquids stems from its ability to smother the fire by cutting off the oxygen supply, thus preventing combustion. In contrast, other types of extinguishers, like wet chemical or foam, may not be suitable for electrical fires as they can conduct electricity or cause further risk to the equipment involved. Therefore, the black carbon dioxide extinguisher is the preferred choice for handling fires involving both flammable liquids and electrical components.
