ABC or Multi-Purpose Fire extinguishers utilize a specially fluidized and siliconized mono ammonium phosphate dry chemical. It chemically insulates Class A fires by melting at approximately 350°F and coats surface to which it is applied. It smothers and breaks the chain reaction of Class B fires and will not conduct electricity back to the operator.

The ABC dry chemical fire extinguisher comes with a dependable drawn-steel cylinder, all metal valve construction, and a stored pressure design. It has a Temperature Range of -65°F to 120°F. There are two options for valve materials where a Chrome-Plated Brass Valve Body and Stainless-Steel Handle and Lever are used in heavy duty Situations. For light to medium duty, an Anodized Aluminum Valve Body, Handle, and Lever are used.
