Extinguishers safe for use on fires near energized electrical equipment include

• A. Water
• B. Dry Chemical
• C. Foam
• D. Carbon Dioxide and Dry Chemical

Answer: (D)

Fires near energized electrical equipment require extinguishing agents that won’t conduct electricity. Carbon dioxide and dry chemical extinguishers are nonconductive, so they can be used on electrical fires without creating a path for current or posing a shock hazard. Water-based extinguishers (like water or foam) can conduct electricity and spread the current, increasing risk to the operator and equipment. That’s why the safe options are carbon dioxide and dry chemical extinguishers.
