What type of fire does a b-1 put out?

A B-1 fire extinguisher is classified as a Class B extinguisher, which is designed to put out flammable liquid fires, such as those involving gasoline, oil, or grease. It uses a dry chemical agent, typically sodium bicarbonate or potassium bicarbonate, to smother the flames and interrupt the chemical reaction of the fire. It is important not to use a B-1 extinguisher on electrical fires or combustible metals, as it is not rated for those types of fires. Always check the labeling to ensure you're using the correct extinguisher for the specific fire type.
