What type of fire extinguishers are suitable for energised electrical equipment?

Fire extinguishers that are suitable for energised electrical equipment are classified as Class C. These extinguishers are specifically designed to handle fires that involve electrical components without conducting electricity back to the user.

Class C extinguishers typically use non-conductive agents such as carbon dioxide (CO2) or dry chemical agents that do not pose a risk of electrical shock. While Class ABC extinguishers can be used on multiple fire types, including ordinary combustibles (Class A), flammable liquids (Class B), and energized electrical equipment (Class C), their versatility makes them a comprehensive choice for environments where different types of fires may occur, including those involving electrical equipment.

The selection of Class ABC extinguishers is particularly valuable in settings like homeless shelters, where various materials are present and the risk of fire from multiple sources is higher. Therefore, Class ABC extinguishers provide a level of safety that ensures preparedness for most fire emergencies, including those involving electricity.
