Which class of fire includes flammable liquids like oils and gasoline?

The correct answer is Class B, which encompasses fires fueled by flammable liquids such as oils and gasoline. Understanding fire classifications is crucial for effective fire safety and response strategies. Class B fires involve materials that can ignite and burn rapidly when in liquid form, such as gasoline, diesel, oil, and other flammable solvents.

The reason Class B is distinct lies in the nature of the fuels; these liquids can create hazardous conditions, including the potential for explosion and rapid spread. Fire extinguishers designed for Class B fires typically use foam, dry chemical agents, or carbon dioxide to smother the flames and prevent oxygen from fueling the fire.

In comparison to the other classes, Class A deals with ordinary combustibles like wood and paper, Class C addresses electrical fires, and Class D is focused on combustible metals such as magnesium or titanium. Each class requires tailored approaches to extinguishment, emphasizing the importance of recognizing the type of fire in order to apply the correct firefighting technique.
