What type of extinguisher is suitable for a Class C fire?

A Class C fire involves electrical equipment, such as wiring, circuit breakers, or appliances. The most suitable extinguishing agents for this type of fire are those that do not conduct electricity, thereby ensuring that the risk of electrocution or electrical shock is minimized while the fire is being extinguished.

Halon extinguishers and CO2 extinguishers are effective because they do not leave residue and can extinguish the fire without conductive materials that could further complicate the situation or pose safety risks. While CO2 extinguishers are also effective, Halon's unique properties make it especially advantageous in situations involving sensitive electronic equipment, which can be sensitive to both water and foam extinguishing agents that might leave unwanted residue or create further electrical hazards.

Water extinguishers and foam extinguishers should never be used on Class C fires as they can conduct electricity, leading to dangerous situations for anyone trying to extinguish the fire. In summary, Halon extinguishers are particularly suited for Class C fires because they effectively suppress fires without introducing additional risks associated with conducting electricity.
