Which class of fire primarily involves flammable liquids and gases?

The correct answer is Class B, which specifically pertains to fires that involve flammable liquids and gases. Materials in this category include substances like gasoline, oil, paint, and solvents that can ignite and burn vigorously.

Understanding fire classes is crucial for implementing the right fire prevention and extinguishing strategies. Class B fires require special fire extinguishers that are designed to combat flammable liquids, as using water on such fires can spread the flames rather than extinguish them.

Other classes of fires involve different materials; for instance, Class A is focused on ordinary combustibles such as wood and paper, Class C pertains to electrical fires, and Class K is specific to cooking oils and fats found in commercial kitchens. Each class has distinct characteristics and requires tailored approaches to manage effectively, making it essential to recognize Class B as the category that includes flammable liquids and gases.
