  • Description

    NFPA 302, Fire Protection Standard for Pleasure and Commercial Motor Craft, is your guide for following cutting edge fire and life safety requirements to reduce the risk of loss of life and property due to fires, explosions, and carbon monoxide (CO) on boats less than 300 gross tons. The 2020 edition introduces new and revised requirements and definitions on a variety of topics relating to fuel systems, electrical systems, and protection equipment such as carbon monoxide detectors. This latest edition includes revisions to the requirements for electrical systems and equipment; fuel systems; carbon monoxide detection equipment; fire extinguishers and fire protection equipment for towing vessels under 300 gross tons.  Due to the increasing popularity of lithium ion battery-powered equipment use in and on recreational water craft this latest edition of the Standard includes new requirements pertaining to lithium ion batteries.  Requirements to address hazards associated with 480 volt electrical distribution systems which are becoming commonplace on larger recreational watercraft and work boats have been added to NFPA 302.
