Which statement about extinguishing agents is correct?

• A. Water can be used on electrical fires
• B. Wet chemicals are used for Class B fires
• C. Dry chemicals can be used for Class C fires
• D. Sodium bicarbonate is used for Class K fires

Answer: (C)

Dry chemicals are effective extinguishing agents for Class C fires, which involve energized electrical equipment. When it comes to electrical fires, utilizing water can be extremely dangerous, as it can conduct electricity and pose a risk of electric shock. Wet chemicals are primarily tailored for Class K fires, typically associated with cooking oils and fats, not Class B fires, which include flammable liquids. Sodium bicarbonate, while it may have firefighting applications, is specifically effective for Class B fires involving combustible liquids, rather than Class K fires, which require agents designed to handle kitchen-related fire hazards. Therefore, the use of dry chemicals for Class C fires effectively addresses the specific needs of extinguishing energized electrical hazards safely.
