What is a key feature of a Type B fire extinguisher?

A Type B fire extinguisher is specifically designed to combat fires that involve flammable liquids, such as gasoline, oil, grease, and other similar substances. The extinguishing agents used in Type B extinguishers, such as foam or dry chemical agents, work to smother the flames and prevent the release of flammable vapors, effectively controlling and extinguishing the fire.

In contrast to fires fueled by solid materials, such as wood, paper, or textiles (for which a different class of extinguishers is appropriate), Type B extinguishers are crucial for safety in environments where flammable liquids are present. Understanding the classification of fire extinguishers is essential for effective fire safety measures, as using the wrong type can exacerbate a fire situation rather than resolving it.
