Class B fires involve:

Class B fires are defined specifically as fires that involve flammable liquids and gases. This category includes substances such as gasoline, oil, paint, solvents, and other combustible liquids that can ignite and produce a significant fire hazard. The flame spread and ease of ignition for these types of materials are a central concern when addressing fire safety protocols.

In contrast, other classifications of fires are based on the dedicated fuel sources. For instance, combustible metals fall under a different category due to the unique characteristics of metal combustion that require specific fire suppression methods. Similarly, paper and cardboard, which are primarily made of organic materials, are classified as Class A fires, while electrical fires relate to Class C, which involves energized electrical equipment.

Understanding these classifications is crucial for selecting the appropriate fire extinguishing agents and strategies, allowing for a more efficient and effective response to various fire incidents.
