What does Class B fire primarily involve?

Class B fires are primarily associated with flammable liquids and gasses. This category includes substances like oils, greases, gasoline, and paints. The critical aspect of Class B fires is that they tend to spread quickly and can create explosive fire hazards if ignited. This is because the vapors from these liquids can easily combust, making it essential for flight attendants and other safety personnel to understand how to effectively manage and extinguish these types of fires.

In contrast, Class A fires involve solid materials, typically wood and paper, while Class C fires concern electrical equipment, and Class D fires pertain to combustible metals. Each class of fire requires specific types of extinguishing agents and strategies for safe and effective management, highlighting the importance of recognizing the fire class to execute the appropriate response.
