Which type of fires are multi-purpose dry chemicals effective against?

Multi-purpose dry chemicals are specifically designed to combat a wide range of fire types, making them extremely versatile in firefighting. They are effective against Class A, B, and C fires.

Class A fires involve ordinary combustibles such as wood, paper, and textiles. Multi-purpose dry chemicals can extinguish these types of fires by smothering the flames and interrupting the combustion process.

Class B fires relate to flammable liquids, gases, and greases. The dry chemicals effectively cut off the oxygen supply and help to cool the burning material, which is crucial in preventing re-ignition.

Class C fires involve energized electrical equipment. Multi-purpose dry chemicals are suitable for these fires as they are non-conductive, allowing for safe application on live electrical components without the risk of electric shock.

Using multi-purpose dry chemical extinguishers in these scenarios ensures a more comprehensive approach to firefighting, addressing different types of materials and sources of ignition while enhancing safety and effectiveness in emergency response situations.
