Which of the following can be used to suppress gasoline and oil fires?
Each correct answer represents a complete solution.
Gasoline and oil are flammable-liquid (Class B) fires. Carbon dioxide and Halon are suitable suppression agents for such fires, and a soda-acid extinguisher generates carbon dioxide that can suppress a small liquid fire. A direct water stream is unsuitable because gasoline and oil float on water, allowing the burning fuel to spread. The U.S. Coast Guard identifies CO2 and Halon or other clean agents as typical extinguishing agents for Class B gasoline and oil fires.
