What class of fire is caused by flammable liquids and gases?

The correct choice is related to fire classes defined by fire protection standards. Fires that are fueled by flammable liquids and gases, such as gasoline, oil, and various solvents, fall under Class B. This classification is essential for fire safety and response, as it informs the types of fire extinguishers and methods used to suppress such fires.

Class B fires require extinguishing agents that can effectively suffocate the flames, such as foam, carbon dioxide, or dry chemical agents, rather than water, which can exacerbate the situation by spreading the flammable liquid. Understanding this classification helps ensure appropriate measures are taken during fire emergencies, making it crucial for safety training and fire response plans.

Opportunities for confusion may arise with other classes, such as Class A, which covers ordinary combustibles like wood and paper, Class C for electrical fires, and Class D for combustible metals. However, these scenarios involve different kinds of materials, which require distinct approaches for fire control. Thus, knowing that flammable liquids and gases correspond to Class B is key for effective fire safety management.
