What type of fire can a Type A fire extinguisher be used on?

A Type A fire extinguisher is specifically designed to combat fires involving ordinary combustible materials. This includes items such as wood, cloth, paper, rubber, and some plastics, which are classified as solid materials that can ignite and burn. The effectiveness of a Type A extinguisher comes from its ability to cool the burning materials and remove the heat that sustains combustion.

The other types of fires specified in the options involve different materials. Gasoline fires are associated with flammable liquids, which require a different extinguisher type. Similarly, electrical fires can pose a risk of shock and require extinguishers that are rated for electrical equipment. Chemical fires can involve reactions that necessitate specific extinguishing agents designed for hazardous substances. Therefore, understanding the classification of fire types and their corresponding extinguishers is crucial for effectively addressing fire emergencies.
