Which of the following is an example of a Class C fire hazard?

A Class C fire hazard specifically refers to fires involving electrical equipment or wiring. This classification is crucial because electrical fires behave differently from those caused by ordinary combustibles or flammable liquids. In a Class C fire, the source of the fire is typically energized electrical equipment, which can include appliances, wiring, or electrical panels.

Using water to extinguish a Class C fire is particularly dangerous because it can conduct electricity, posing an electrocution risk. Therefore, it is essential to use appropriate extinguishing agents designed for electrical fires, such as carbon dioxide or dry chemical extinguishers.

The other options pertain to different fire classes: paper is associated with Class A fires (ordinary combustibles), grease with Class B fires (flammable liquids), and rubber can also fit into Class A due to its combustibility. Understanding these distinctions aids flight attendants in properly identifying hazards and responding to emergencies effectively.
