NFPA 306: Standard for the Control of Gas Hazards on Vessels
NFPA 306: 船上气体危险性控制标准
1.1 Scope.
1.1.1 This standard applies to vessels that carry or burn as fuel, flammable or combustible liquids. It also applies to vessels that carry or have carried flammable compressed gases, flammable cryogenic liquids, chemicals in bulk, or other products capable of creating a hazardous condition.
1.1.2 This standard describes the conditions required before a space can be entered or work can be started, continued, or started and continued on any vessel under construction, alteration, or repair, or on any vessel awaiting shipbreaking.
1.1.3 This standard applies to cold work, application or removal of protective coatings, and work involving riveting, welding, burning, or similar fire-producing operations.
1.1.4 This standard applies to vessels while in the United States, its territories and possessions, both within and outside of yards for ship construction, ship alteration, ship repair, or shipbreaking.
1.1.5 This standard applies specifically to those spaces on vessels that are subject to concentrations of combustible, flammable, and toxic liquids, vapors, gases, and chemicals as hereinafter described. This standard is also applicable to those spaces on vessels that might not contain sufficient oxygen to permit safe entry.
1.1.6 This standard applies to land-side confined spaces, whether stationary or mobile, or other dangerous atmospheres located within the boundaries of a shipyard or ship repair facility as defined by 29 CFR 1915.11.
1.1.7 This standard applies to Marine Chemists performing activities related to inspection and certification procedures described in this standard and consulting services connected therewith on board any vessel.
1.1.8* This standard does not apply to physical hazards of tanks and confined or enclosed spaces on a vessel or vessel sections, or in the shipyard. For the purposes of this standard, physical hazards do not include fire and explosion hazards.
Apply the 2009 NFPA 306 to reduce fire and explosion risks aboard marine vessels and in shipyards.
Essential to fire and life safety, NFPA 306: Standard for the Control of Gas Hazards on Vessels provides minimum requirements and conditions for use in determining that a space or area on a vessel, or in a shipyard or ship repair facility, is safe for entry or work. It specifies safety requirements for vessels carrying or burning as fuel flammable or combustible liquids, and also applies to vessels carrying or having carried flammable compressed gases, chemicals in bulk, or other products capable of creating a hazardous condition. NFPA 306 is the standard of practice that NFPA®-certificated Marine Chemists must follow in carrying out their duties where required by regulations of the U.S. Department of Labor/ OSHA and the U.S. Coast Guard.
The 2009 edition is based on new data and critical lessons learned:
· Revised definition of adjacent spaces now includes areas affected by hot work and where slag, products of combustion, or sparks would be expected to fall or accumulate.
· The term "vessel" is expanded to include floating structures not primarily designed as a means of transportation on water such as offshore drilling, production, and/or storage vessels.
· Added definitions address the terms host employer, contract employer, and multi-employer workplace
Also includes revised requirements necessary for obtaining a Marine Chemist’s Certificate and the requirements for maintaining the Certificate. This edition of NFPA 306 is essential for everyone concerned with or responsible for marine fire and life safety or contracting aboard marine vessels or in shipyards. (Softbound, 22 pp., 2009)
