What class of fire is represented by a jet fuel fire during refueling?

A jet fuel fire during refueling is categorized as a Class B fire. This classification includes flammable liquids and gases, such as gasoline, oil, and aviation fuel. Class B fires are characterized by their capability to consume materials that are in liquid form and can spread quickly when ignited.

Understanding the classification is crucial for flight attendants and ground crew, as it dictates the type of fire extinguishers and methods used to combat the fire effectively. For example, using water on a Class B fire could exacerbate the situation, as it can spread the burning liquid. Instead, foam, dry chemical, or carbon dioxide extinguishers are recommended for such fires, as they can effectively smother the flames and prevent re-ignition.

In contrast, Class A fires concern ordinary combustibles like wood and paper, Class C fires involve energized electrical equipment, and Class D fires pertain to combustible metals. Each class requires different approaches for safe and effective suppression, highlighting the importance of correct fire classification in emergency response.
