What color shape indicates a Class A fire on a fire extinguisher?

A green triangle represents a Class A fire on a fire extinguisher. Class A fires involve ordinary combustible materials, such as wood, paper, and cloth. The green triangle symbol is used to easily identify that an extinguisher is suitable for tackling these types of fires. This visual cue helps firefighters and laypersons quickly recognize the appropriate fire extinguisher needed for specific fire types, enhancing safety and efficiency in emergency situations.

Visual identification through color and shape is a critical aspect of fire safety, as it allows for rapid decision-making in potentially dangerous scenarios. Each class of fire has a designated symbol, making it crucial for users to familiarize themselves with these indicators to effectively respond to different fire types.
