Class B


A fire extinguisher labeled with letter "B" is for use on Class B fires. Class B fires are fires that involve flammable and combustible liquids such as gasoline, alcohol, diesel oil, oil-based paints, lacquers, etc., and flammable gases.





Class C


A fire extinguisher labeled with letter "C" is for use on Class C fires. Class C fires are fires that involve energized electrical equipment.

Reply:Class-C fires are electrical fires, where the heat side of the fire triangle is caused by, for example, short-circuiting machinery or overloaded electrical outlets. These fires can be a severe hazard to firefighters using water: when the solid stream of water hits the electrical fire, the electricity is conducted through it and into the hose, then into the firefighter's body. Electrical shocks have caused many firefighter deaths.





There are two main ways of fighting a class-C fire: cutting off its oxygen, or simply turning off the electricity to the fire from a breaker. A class-C fire can be put out with a fire extinguisher rated for class-C fires, or with protein foam, but the primary approach is to simply turn off the power as noted above. This causes the fire to become an ordinary class-A fire, or perhaps to die out entirely. The agents used to extinguish fire of class-c are sodium bicarbonate, carbondioxide, halotron, potassium bicarbonate and PKP.








In Europe and Australasia, a different classification system is used.





Class C: Fires that involve flammable gases, such as natural gas, hydrogen, propane, butane
