Carbon Dioxide Fire Suppression Systems on Commercial Vessels
The Coast Guard is amending the current regulations for fire suppression systems on several classes of commercial vessels. The amendments clarify that approved alternatives to carbon dioxide systems may be used to protect some spaces on these vessels, and set general requirements for alternative systems. Additionally, certain new carbon dioxide systems must be equipped with lockout valves and odorizing units to protect persons after a carbon dioxide discharge. By requiring these features on carbon dioxide systems and by making a wider range of fire suppression systems available, the regulations advance the Coast Guard's strategic goals of promoting marine safety and maritime mobility.
