A 20 lb CO2 fire extinguisher is classified as a Class B and Class C extinguisher. Class B fires involve flammable liquids like gasoline, oil, and grease, while Class C fires involve electrical equipment. CO2 extinguishers work by displacing oxygen and removing heat, making them effective for these types of fires. However, they are not suitable for Class A fires, which involve ordinary combustibles like wood and paper.

What is a B-I or B-II US Coast Guard rating for a fire extinguisher?
B-I and B-II refer to the relative fire extinguishing capacity of approved USCG fire extinguishers, depending upon the type of extinguishing agent used. Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating BEFORE the letter B, for class B extinguishers, indicates the approximate number of square feet of fire it can extinguish (i.e., with no significant depth). The numerical rating (I, II, III) AFTER the letter B indicates Coast Guard classification. For example, a UL 5-B:C, rated for 5 sq ft of liquid fire, would be a USCG B-I extinguisher (with 2 pounds of dry chemical). To obtain a USCG B-II rating you would need the equivalent of 10 pounds of dry chemical, such as having two UL 3-A, 40-B:C extinguishers, or a 15-pound CO2 extinguisher, or 2 1/2 gallons of AFFF "foam" (UL 3-A:20B). A 20-pound dry-chemical (120-B:C) would meet USCG B-III requirements. USCG ratings go as high as V, which is a big extinguisher on wheels.
