Which of the following is NOT a type of extinguisher for Type C fires?

For fires involving energized electrical equipment, commonly referred to as Type C fires, the use of specific fire extinguishers is crucial. The correct answer recognizes that water mist extinguishers are not suitable for this type of fire. Water is conductive and can pose a serious risk when it comes into contact with live electrical equipment, potentially leading to electric shock or further fire spread.

In contrast, carbon dioxide extinguishers, dry chemical extinguishers, and halogenated agents are all effective for Type C fires. Carbon dioxide works by displacing oxygen, which is essential for combustion. Dry chemical extinguishers contain agents that can interrupt the chemical reaction of the fire, and halogenated agents are specifically designed for fires involving electrical equipment without leaving residue, making them ideal for sensitive environments. Therefore, understanding the properties and appropriate uses of these extinguishers is pivotal for safety during Type C fire incidents.
