All vessels, including PWC, are required to have a Type B USCG–approved fire extinguisher 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
- Closed living spaces
- Permanently installed fuel tanks
Check all extinguishers annually to make sure they are fully charged. Extinguishers must be maintained in usable condition and should be serviced at least every two years. Refer to the label for additional servicing information.
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. Only fire extinguishers that are USCG–approved are legal for use on vessels.
