What is an example of a Class C Fire?

The identification of a Class C fire is based on the type of material that is burning. Class C fires involve energized electrical equipment, which requires specific firefighting techniques and extinguishing agents to avoid further hazards, such as electrical shock or additional fire spreading.

In this scenario, a panel of exposed electrical circuits is explicitly related to electrical equipment, thereby categorizing the fire as Class C. When dealing with Class C fires, the typical firefighting agents like water are not suitable, as they can conduct electricity and exacerbate the situation.

The other scenarios presented do not involve electrical equipment or circuits. Therefore, they are classified differently: burning metal studs would pertain to Class D fires (combustible metals), oily rags would be categorized as Class B (flammable liquids), and burning paint thinner could also fall into Class B since it involves volatile liquids. Understanding the correct classifications can help security personnel make informed decisions during emergencies, ensuring both safety and effectiveness in fire response.
