What type of fire does a Type B extinguisher specifically target?

A Type B extinguisher is specifically designed to combat fires involving flammable liquids and gases, which include substances like gasoline, oil, grease, and solvents. These types of fires occur when such materials ignite, presenting a significant danger due to their ability to spread quickly and the potential for explosions.

Flammable liquids and gases behave differently compared to solid materials or electrical sources, which is why specialized extinguishing agents are necessary for effective fire suppression in these scenarios. Type B extinguishers generally use dry chemical agents or foam to smother flames and interrupt the chemical reaction fueling the fire, making them highly effective in these situations.

Other types of fires, such as Class A fires that involve solid combustibles like wood and paper, or Class C fires that involve electrical equipment or cooking oils, require different types of extinguishers designed to address the unique challenges presented by those materials. Therefore, understanding that Type B extinguishers are tailored for flammable liquids and gases is essential for effective fire safety and response.
