In case of a chemical fire, which type of fire extinguisher should be utilized?

In the case of a chemical fire, a carbon dioxide extinguisher is the most suitable option because it effectively extinguishes fires involving flammable liquids and gases, as well as electrical fires. Carbon dioxide works by displacing oxygen, which is necessary for combustion, thereby suffocating the fire without leaving any residue that could complicate cleanup or damage surrounding equipment.

While other extinguishing agents may be effective for specific types of fires, they are not ideal for chemical fires in general. For example, a water extinguisher might exacerbate certain chemical fires, particularly those involving flammable liquids or reactive materials. A foam extinguisher is limited to class B fires and may not be effective for all chemical incidents. A dry powder extinguisher can be used for a variety of fires, including those involving flammable solids and liquids, but it may not be as effective or clean as carbon dioxide for certain chemical fires. Therefore, choosing a carbon dioxide extinguisher provides a safer and more efficient means of tackling chemical-related fire emergencies.
