What is the recommended extinguishing agent for Class C fires?

For Class C fires, which involve energized electrical equipment, the recommended extinguishing agent is primarily one that is a smothering agent and not a conductor of electricity. This is crucial because using a conductor, such as water, on an electrical fire can create further hazards, including electric shock or electrocution.

When dealing with Class C fires, it is essential to use agents that do not conduct electricity. Fire extinguishers classified as non-conductive, such as CO2 or dry chemical extinguishers, fall into this category. A smothering agent that is safe for use around electrical components ensures that the fire can be extinguished without risking an electrical shock to the person using the extinguisher or exacerbating the fire.

The other options are less appropriate because water can conduct electricity and is inappropriate for this type of fire. While dry chemical extinguishers can also be effective, the focus on a smothering agent that ensures safety from electrical conduction highlights the priority of preventing electrical hazards in these situations. Foam agents, although effective for various types of fires, are generally not used for Class C fires due to conductivity concerns.
