Class C fires require?

• A. That you cut off the current as soon as possible
• B. Using a water extinguisher
• C. Using a CO2 extinguisher
• D. Evacuate immediately

Answer: (A)

Class C fires are fires involving energized electrical equipment. The essential first action is to cut off the current to the equipment as soon as it can be done safely. Removing the electrical source eliminates the shock hazard and stops the fire from being fed by electricity, making any suppression work safer and more effective. Water should not be used on energized electrical fires because it conducts electricity and can cause electrocution. After power is cut, a nonconductive extinguisher like CO2 or a dry chemical can be used if you’re trained and the area is safe. Evacuation becomes necessary if you cannot safely disconnect power or if the fire is beyond control.
