A Class "C" fire involves electrical equipment, which poses unique risks and requires specific types of fire extinguishing agents. The most appropriate choice for a Class "C" fire is a dry chemical extinguisher. These extinguishers typically use agents such as sodium bicarbonate or potassium bicarbonate, which are effective in interrupting the chemical reaction of the fire while also ensuring the safety of the user against electrical shock. Using a water extinguisher or a foam extinguisher on a Class "C" fire can be hazardous because water conducts electricity, potentially leading to severe injuries or further spreading of the fire. Therefore, dry chemical extinguishers are specifically designed to safely combat electrical fires without these risks. This makes them a crucial component of any fire safety plan involving electrical equipment.
