For motor vessels over 65 feet, which type of extinguisher is required?

For motor vessels over 65 feet, the regulation requires the use of a B-II type fire extinguisher. This type of extinguisher is specifically designed to combat fires involving flammable liquids, which is crucial for vessels operating with fuel and other combustibles often found on board.

The B-II extinguisher has a higher capacity and can effectively handle larger fires, which aligns with the increased risks associated with larger vessels. It can typically extinguish fires in flammable liquids such as gasoline or oils, making it essential on any motor vessel of this size to ensure safety and meet regulatory standards.

The need for a more robust extinguisher on larger vessels is informed by the potential for more significant incidents and the requirement to have adequate firefighting resources readily available. A B-I type extinguisher would not provide sufficient capacity, and A-I and C-I types are not designed for flammable liquid fires. This understanding underlines the importance of equipping larger vessels with the appropriate type of fire suppression equipment.
