Requirements to Carry Fire Extinguishers

Most vessels are required to have a Type B fire extinguisher on board, in serviceable condition, and readily available. The only exceptions are:

• Any non-motorized boat
• Class A or Class 1 boats whose construction will not permit the entrapment of flammable gases or vapors

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.
