An example of a B-I extinguisher?

• A. 15 Pound Carbon Dioxide
• B. 5 Pound Water
• C. 10 Pound Foam
• D. 2 Pound Dry Chemical

Answer: (D)

An extinguisher labeled for Class B fires on a vessel is intended for flammable-liquid fires, and the B-I designation usually points to a small dry chemical unit. A two-pound dry chemical extinguisher fits that description best because dry chemical powders rapidly interrupt the chemical reactions occurring in liquid fires and are effective across the common flammable liquids found on boats. The compact two-pound size is typical for onboard use on smaller craft, offering quick, versatile protection against spills like gasoline or oil fires. The other media are for different situations: water is for ordinary combustibles, foam is for some A and B fires but not the standard B-I on small boats, and CO2 is more suited to electrical fires and enclosed spaces. Thus, the two-pound dry chemical extinguisher is the typical example of a B-I extinguisher.
