It's the Law

Fire Extinguishers


All vessels, including PWCs, are required to have a Type B fire extinguisher(s) on board if one or more of the following conditions exist:

  • Closed compartments under seats where portable fuel tanks may be stored
  • Closed storage compartments in which flammable or combustible materials may be stored
  • Double-bottoms not sealed to the hull or which are not completely filled with flotation material
  • Closed living spaces
  • Permanently installed fuel tanks

Approved types of fire extinguishers are identified by the following marking on the label—
"Marine Type USCG Approved"—followed by the type and size symbols and the approval number.

Extinguishers should be placed in an accessible area—not near the engine or in a compartment, but where they can be reached immediately. Be sure you know how to operate them, and inspect extinguishers regularly to ensure they are in working condition and fully charged.

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