How much area can an untrained person expect to put out with a 60B extinguisher?

An untrained person can expect to effectively put out an area of approximately 60 square feet with a 60B extinguisher. This rating signifies that the extinguisher is suitable for handling a class B fire, which involves flammable liquids such as gasoline, oil, or grease. The number indicates the coverage area that an untrained individual can manage confidently while using the extinguisher to suppress a fire of that type.

The rating is based on controlled tests simulating realistic fire scenarios, allowing for this specific area coverage. This means that a person using a 60B extinguisher should focus their efforts within this area for the best chance of extinguishing the fire successfully. Understanding this coverage helps ensure safety and effectiveness when using fire extinguishers in emergency situations.
