Dry Powder Extinguishers (Class A, B, C, D* and Electrical fires if the equipment is less that 1,000v)
Label Colour: BLUE
Dry Powder extinguishers are versatile and can be used on Class A, B, C, and Electrical fires. They work by interrupting the chemical reaction of the fire, preventing it from spreading. There are two types of dry chemical extinguishers: ABC and BC. ABC extinguishers are filled with monoammonium phosphate and are the most common type, while BC extinguishers are filled with sodium bicarbonate. Dry chemical extinguishers should not be used on Class F fires or electrical fires where the equipment exceeds 1000v. *Class D Fires require a specialist L2 Metal Powder Extinguisher.
