Dry Chemical Fire Extingusihers

The dry chemical fire extinguisher is the most widely used of all types of extinguishers. There are three basic types of dry chemical extinguishers, each of which has advantages and disadvantages based on the hazard.

1) ABC (or multi-purpose) fire extinguishers use ammonium phosphate as the extinguishing agent. The ABC fire extinguisher is effective on Class A, B, or C fires.

2) Regular dry chemical fire extinguishers use sodium bicarbonate as the extinguishing agent. The regular dry chemical fire extinguisher is effective on Class B & C fires.

3) Purple K or potassium bicarbonate fire extinguishers are sometimes selected in lieu of regular dry chemical (sodium bicarbonate) extinguishers due to their greater fire extinguishing capabilities. Purple K extinguishers are effective on Class B & C fires.
