Q: I am looking to purchase an all-purpose fire extinguisher for my garage. What type should I buy?
A: Fire extinguishers are designed to put out specific types of fires. Fires need oxygen, heat, and fuel to exist. A fire extinguisher removes one of these requirements to put a fire out. A-type extinguishers put out wood, paper, and cloth fires. B-type extinguishers put out gasoline, oil, and grease fires. C-type extinguishers put out electrical fires. An all-purpose fire extinguisher will have a combination A-B-C rating.
