A dry chemical extinguisher rated 60-B is capable of handling a fire involving which distance of flammable liquid?

A dry chemical extinguisher rated 60-B indicates its effectiveness in combating flammable liquid fires based on the size of the fire it can handle. The “60” in the rating signifies that the extinguisher is suitable for a fire involving a maximum flammable liquid area of 60 square feet.

When dealing with flammable liquids, it's essential to understand that the rating directly correlates to the dimensions of the fire, which can be visualized as a square or rectangular area. Thus, a 60-B extinguisher is designed to handle a fire that would cover an area of approximately 60 feet in distance if one imagines the fire spread out in a more linear fashion. Therefore, the correct answer regarding the capability of a dry chemical extinguisher rated 60-B would be a distance of 60 feet involving flammable liquids.

This rating reflects the extinguisher's ability to effectively suppress the flames and prevent re-ignition within this specified distance and area of flammable liquid.
