A Class C fire involves which type of hazard?

Answer: B — Fires in energized electrical equipment

A Class C fire specifically refers to fires that involve energized electrical equipment. This classification is crucial because using the wrong extinguishing agent on a Class C fire can lead to severe hazards, including the risk of electrocution or worsening the fire. Understanding the classification of fires is essential for effective fire response. Class C fires can arise from various sources, such as faulty wiring, overloaded equipment, or malfunctioning appliances. The appropriate action typically involves cutting off the electrical supply to the equipment before attempting to extinguish the fire, and using an extinguishing agent that is safe for electrical fires, such as a dry chemical extinguisher or carbon dioxide, to prevent conductive hazards. The other options represent different fire classifications: fires in wooden structures are categorized as Class A, flammable liquids fall under Class B, and cooking equipment typically involves Class K fires, which are related to oils and fats. Knowing these distinctions helps ensure the correct firefighting approach and enhances safety.
