>Proposed Rule on Carbon Dioxide Fire Suppression Systems on Commercial Vessels

>The Coast Guard is proposing to amend the current regulations for fire suppression systems on several classes of commercial vessels. The amendments would clarify that approved alternatives to carbon dioxide systems may be used to protect some spaces on these vessels and would set general requirements for alternative systems. Additionally, new and existing carbon dioxide systems, when used in spaces that can be accessed by persons on board the specified commercial vessels, would need to be equipped with lockout valves and olfactory additives to protect persons in the event of a carbon dioxide discharge. Comments on the proposal rule should be submitted by May 25.
