Can you use PKP on a electrical fire?

No, you should not use PKP (which typically refers to fire extinguishers containing potassium bicarbonate) on electrical fires. Electrical fires require specific extinguishing agents, such as Class C fire extinguishers, which use non-conductive materials like carbon dioxide or dry chemical agents. Using water or inappropriate extinguishing agents can pose serious risks, including electrocution. Always ensure you use the correct type of extinguisher for the specific fire class.
