Which type of fire involves flammable liquids, such as gasoline?

The correct response indicates that Class B fires involve flammable liquids, such as gasoline. Class B fires are specifically characterized by combustible liquids that can ignite and produce flames. This category includes substances like oil, gasoline, grease, and solvents, which are common in both residential and industrial settings.

Understanding the classification of fires is crucial for safety and effective firefighting tactics. For example, using water to extinguish a Class B fire could be extremely dangerous, as it may spread the flammable liquid rather than extinguishing the fire. Instead, specialized fire extinguishers that are rated for Class B fires, which often contain dry chemicals or foam agents, should be used to effectively smother the flames.

In contrast, Class A fires involve ordinary combustibles such as wood, paper, and fabric, Class C fires pertain to electrical fires, and Class D fires involve combustible metals. This classification helps responders identify the best approach for fire suppression and ensures the safety of both individuals and property involved.
