Which class of fire involves flammable liquids and gases?

The correct answer involves understanding the classifications of fire types based on the materials that are burning. Class B fires are specifically associated with flammable liquids and gases. This includes substances such as gasoline, oil, propane, and other similar materials that can ignite and spread quickly due to their volatile nature.

When dealing with Class B fires, it is essential to use the appropriate extinguishing agents, such as foam or dry chemical extinguishers, which are designed to smother the flames and prevent ignition. This class of fire requires particular attention since using water can exacerbate the situation, causing flammable liquids to splatter and potentially spread flames further.

In contrast, Class A fires refer to ordinary combustibles like wood, paper, and fabric; Class C fires involve energized electrical equipment; and Class D fires pertain to combustible metals. Understanding these distinctions is crucial for effective firefighting and safety protocols in wildland fire management and other fire safety practices.
