Class B fire extinguishers are specifically designed for fires involving flammable liquids and gases, such as gasoline, oil, grease, solvents, and propane. These extinguishers work by smothering the fire and interrupting the oxygen supply.
Carbon dioxide (CO2) extinguishers and dry chemical extinguishers, such as those containing monoammonium phosphate or sodium bicarbonate, are commonly used for Class B fires. It’s important to follow safety guidelines and avoid using water-based extinguishers on Class B fires, as they can spread the flames.
Class C fire extinguishers are suitable for fires involving electrical equipment, such as wiring, appliances, and circuit breakers. These extinguishers are non-conductive and designed to interrupt the electrical current, thus eliminating the risk of electrical shock.
