What type of fires can a red ABC fire extinguisher put out?

A red ABC fire extinguisher is designed to combat three types of fires effectively, making it a versatile tool for fire suppression. The "A" classification refers to fires involving ordinary combustibles like wood and paper. The "B" classification is for flammable liquids, including grease and chemicals. The "C" classification applies to electrical fires.

This combination means that a red ABC extinguisher can safely extinguish fires caused by combustible materials, flammable liquids, as well as fires sparked by electrical equipment. The versatility of the ABC extinguisher allows it to be utilized in various environments, such as homes, offices, and industrial settings, where multiple fire hazards may be present. Thus, the inclusion of grease, electrical, and chemical fires in the correct answer reflects the multifunctionality of the red ABC extinguisher.
