A vessel with a permanently installed fuel tank is at risk of fires that primarily involve flammable liquids, such as gasoline or diesel fuel. This type of fire is best managed with a fire extinguisher classified as Type B. Type B extinguishers are specifically designed to combat fires involving flammable liquids, such as oils, gasoline, and grease.

When dealing with a fire fueled by these substances, it is crucial to use an appropriate extinguisher that can effectively smother the flames without spreading the fire. The materials used in a Type B extinguisher help to prevent the fire from re-igniting after being extinguished, which is vital in environments where flammable liquids are present.

In contrast, Type A extinguishers are meant for ordinary combustibles like wood and paper, Type C is for electrical fires, and Type D is intended for combustible metals, none of which are suitable for tackling fires caused by flammable liquids found in a boating environment with a fuel tank. Therefore, equipping a vessel with a Type B extinguisher is essential for safety and effective fire response.
