Which type of aircraft fire is characterized as a Class B fire?

A Class B fire is characterized by the involvement of flammable liquids and gases. In the context of aircraft firefighting, this includes fuels, oils, and other liquid materials that can ignite and spread rapidly, making them particularly dangerous in an aviation environment. Understanding that Class B fires require specific extinguishing agents, such as foam or dry chemical agents designed to smother and separate the fuel from oxygen, is crucial for effective response.

In contrast, an electrical fire falls under Class C, as it involves energized electrical equipment. Kitchen fires typically relate to grease fires, which can be classified as Class K fires, especially in the context of aviation catering or onboard meal preparation. Combustible solid fires are classified as Class A fires, primarily involving materials such as wood, paper, and textiles. Recognizing these distinctions is important for effective firefighting and safety protocols at airports.
