Class B fires are typically caused by what?

Class B fires are characterized by the involvement of flammable liquids and gases. These fires can arise from substances such as gasoline, oil, grease, and solvents, which are all classified under this category due to their ability to ignite and produce hazardous flames. Understanding the nature of Class B fires is critical for effective fire prevention and response in aviation and other industries where flammable liquids are prevalent.

In contrast, Class A fires, for example, are linked to combustible materials such as wood or paper, while Class C fires involve electrical faults and are initiated due to faulty wiring or malfunctioning electrical equipment. Reactivities of metals pertain to another category of fires, known as Class D fires, which involve combustible metals like magnesium or titanium. Recognizing these distinctions helps personnel prepare and respond appropriately in emergencies.
