It's the Law: Required Equipment

Fire Extinguishers

  • All vessels are required to have a Type B U.S. Coast Guard-approved fire extinguisher(s) on board if one or more of the following conditions exist:
    • Inboard or inboard/outboard engines
    • Closed compartments under seats where portable fuel tanks may be stored
    • Permanently installed fuel tanks
    • Closed or semi-closed living spaces
    • Devices on board that consume petroleum products (e.g., stoves, lanterns)
  • 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 type and quantity required for your vessel:

Fire Extinguisher Charge Indicators

Check the charge level of your fire extinguishers regularly. Replace them immediately if they are not fully charged.

To check this style of extinguisher, depress the green button. If it is fully charged, the green button should pop back out immediately.
