This page lists extinguishers that have solely a Class AB rating. For extinguishers that can handle other types of fires go back to the By Class page and select one of those classes.
Class A fires involve ordinary materials like burning paper, lumber, cardboard, plastics etc. Class B involve flammable or combustible liquids such as gasoline, kerosene, and common organic solvents used in the laboratory. The units shown here are good for handling either kind of threat, but should not be used on energized electrical equipment or burning metals.
