What class of fire is a Class B extinguisher designed for?

A Class B extinguisher is specifically designed to fight fires that involve flammable liquids and gases. This includes materials like gasoline, oil, paints, solvents, and other combustible liquids. The effectiveness of a Class B extinguisher stems from its ability to suppress flames produced by these substances, which can be highly volatile and dangerous.

In contrast, kitchen fires typically involve grease and oils, which are classified as Class K fires, necessitating a different type of extinguisher specifically designed for such scenarios. Ordinary combustibles, such as wood and paper, fall under Class A fires and require extinguishers suited for those materials. Lastly, electrical fires involve energized electrical equipment and should be addressed with Class C extinguishers, which are suitable for fires caused by electrical sources.

Understanding these classifications helps ensure that the correct extinguisher is used in an emergency, maximizing safety and effectiveness.
