What is a key characteristic of a fire extinguisher designed for electrical fires?

A fire extinguisher designed for electrical fires must be labeled as suitable for Class C fires. This classification indicates that the extinguisher is specifically formulated to safely combat fires involving live electrical equipment. Using the correct class of extinguisher is critical because employing water or other inappropriate extinguishing agents on electrical fires can lead to severe hazards, including electrical shock and the potential for the fire to escalate.

Class C extinguishers typically contain agents such as CO2 (carbon dioxide) or dry chemical powders that do not conduct electricity, making them safe choices for extinguishing electrical fires. Understanding the classifications and proper use of fire extinguishers is essential for ensuring safety during fire emergencies. The labeling serves as a quick reference for users to identify which extinguisher to use in the event of an electrical fire.
