When encountering an electrical fire, what is the safest first action?

Using a fire extinguisher designed for electrical fires, commonly classified as Class C, is the safest first action when confronted with an electrical fire. Class C fire extinguishers contain non-conductive agents specifically designed to extinguish fires that involve electrical equipment, such as wiring, appliances, or circuit breakers. This is critical because using the wrong type of extinguisher, such as one containing water, can lead to severe injury or further accidents due to the conductive nature of water, which can create a path for electric shock.

In addition, Class C extinguishers typically utilize materials like dry chemicals (such as bicarbonate or chloride) that effectively disrupt the combustion process without posing electrical hazards. Thus, selecting the appropriate extinguisher maximizes safety and efficacy when dealing with electrical fires.
