1. Water fire extinguisher: Water fire extinguishers are designed to extinguish Class A fires, which involve ordinary combustible materials such as wood, paper, and cloth. They are not suitable for use on Class B (flammable liquids) or Class C (electrical) fires.
2. CO2 fire extinguisher: CO2 fire extinguishers are designed to extinguish Class B and Class C fires. Class B fires involve flammable liquids such as gasoline and oil, while Class C fires involve energized electrical equipment. CO2 extinguishers work by displacing oxygen and removing heat from the fire.
3. Dry chemical fire extinguisher: Dry chemical fire extinguishers are versatile and can be used on Class A, B, and C fires. They contain a dry chemical powder that smothers the fire and interrupts the chemical reaction. Dry chemical extinguishers are commonly found in workplaces as they can be used on a variety of fire types.
