Which color shape on a fire extinguisher indicates a Class C fire?

A blue circle on a fire extinguisher is specifically designated to indicate a Class C fire, which involves electrical equipment. This color-coding is part of a standardized system to easily identify the type of fire that the extinguisher is designed to combat. Knowing the color associated with different classes of fires is crucial for anyone involved in fire safety or firefighting, as it allows for rapid assessment and response in emergency situations.

Class C fires involve energized electrical equipment, and using an extinguisher that is not rated for this type of fire can pose serious risks, including electric shock or explosion. The blue circle alerts users that the extinguisher can be safely used on such fires without the risk of conducting electricity. Understanding this classification and its associated symbols is an essential part of fire safety training, ensuring that individuals can make informed decisions when faced with a fire.
