In the context of fire safety, which material is related to Class C fires?

  1. Paper

  2. Wood

  3. Electrical Equipment

  4. Flammable Liquids

The correct answer is: Electrical Equipment

Class C fires involve flammable materials that are associated with electrical equipment, making this the correct answer. This category of fire is specifically related to incidents where electrical sources are present, such as wiring, appliances, or circuits. When dealing with a Class C fire, it's crucial to use appropriate extinguishing methods, as using water can pose significant risks, including electric shock. In contrast, the other listed materials correspond to different classes of fires: Paper and wood are associated with Class A fires, which involve ordinary combustibles, while flammable liquids are related to Class B fires, which encompass liquids that can ignite easily, such as gasoline or oil. Understanding the classification of fires helps ensure appropriate response and safety measures are employed, highlighting the importance of recognizing the nature of the material involved in a fire incident.
