For vessels between 100 GT and 300 GT, how are fire extinguisher requirements typically determined?

Fire extinguisher requirements for vessels between 100 GT and 300 GT are determined based on the size and type of the vessel. This approach takes into consideration various factors such as the vessel's purpose, the number of people on board, the materials used in its construction, and specific fire hazards that may be present.

For instance, larger or more complex vessels may require a greater number of extinguishers or specific types to address unique risks, such as the possibility of fires arising from equipment, fuel systems, or living quarters. Additionally, regulatory standards, like those provided by the U.S. Coast Guard, stipulate that fire extinguishers must be strategically placed and readily accessible in various locations to ensure safety.

This methodology ensures that each vessel is equipped in a manner appropriate to its operational context and potential fire risks, which is why relying solely on horsepower, the location of extinguishers, or a random selection process would not adequately fulfill safety requirements.
