The three most common types of fires are:
Class A fires involve combustible materials such as wood, paper, cloth, or plastics. They can be extinguished with water, foam, or dry chemicals. Class B fires involve flammable liquids such as gasoline, oil, or propane. They can be extinguished with foam, dry chemicals, or carbon dioxide. Class C fires involve electrical equipment such as wiring, appliances, or motors. They can be extinguished with carbon dioxide or dry chemicals. It's important to note that these fires can also involve Class A or Class B materials, and the electrical equipment must be de-energized or turned off before attempting to extinguish the fire.
