What is the primary hazard associated with Class C fires?

The primary hazard associated with Class C fires involves electrical shock and fires. Class C fires are specifically categorized as those involving energized electrical equipment. This is significant because when responding to such fires, firefighters must be concerned about the risk of electrical shock from the live electrical components involved.

Standard firefighting techniques that involve water or certain foams can be dangerous if applied directly to energized electrical equipment, as water is a conductor of electricity. Therefore, the approach to extinguishing Class C fires often requires the de-energization of the electrical source before applying any other extinguishing agents. Firefighters must be aware of their surroundings and the risk of electrocution when tackling these fires, which underscores the unique hazards that Class C fires present compared to other types of fires involving flammable solids or liquids.

In summary, understanding that Class C fires primarily pose the risk of electrical shock is crucial for ensuring both firefighter safety and effective fire suppression tactics.
