It's the Law

Fire Extinguishers

All non-exempt vessels, including PWC, are required to have a Type B, USCG-approved fire extinguisher(s) on board.

While a vessel may be exempt from the fire extinguisher requirement, all vessel operators are encouraged to carry a fire extinguisher on board.

Approved types of fire extinguishers are identified by the following marking on the label—"Marine Type USCG Approved"—followed by the size and type symbols and the approval number. Only USCG–approved fire extinguishers are legal for use on vessels.

Extinguishers should be placed in an accessible area away from the engine. Be sure you know how to operate them, and check all extinguishers regularly.

Use this chart to determine the size and quantity required for your vessel.
