For many years, halon extinguishers were recognized as the best choice for protecting watercraft.
Halon was a clean, gaseous agent that quickly put out fires without collateral damage.
However, this prohibition does not apply to emergency releases of halons for legitimate fire extinguishing , explosion inertion, or other emergency applications for which the systems or equipment were designed.
Halon is not a banned product, although some states are banning the sale of certain hand-held extinguishers for noncommercial use.
Effective January 1, 1994, the production and importation of new halon was banned in the developed world by international agreement-the Montreal Accord.
