What does a red label typically indicate on a fire extinguisher?

A red label on a fire extinguisher signifies that it is designed to combat Class A fires, which involve ordinary combustibles such as wood, paper, and cloth. The color coding system is important for the quick identification and proper use of fire extinguishers in emergency situations. Class A extinguishers typically utilize water or foam agents that can cool and extinguish these types of fires effectively. Recognizing the red label helps firefighters and individuals in emergencies to quickly select the appropriate extinguisher to use, ensuring a more effective response to the fire.
