Water Mist Fire Suppression System
CLIA's oceangoing members have adopted this policy to reflect best practices regarding water mist fire suppression systems on cruise ships. This policy is effective on December 31, 2015, and applies to cruise ships fitted with a water mist fire suppression system in category “A” machinery spaces.
CLIA cruise lines are to eliminate to the extent practicable any programmed time delay from an automated activation sequence of the water mist system and to provide a redundant source of power or supply pressure to the water mist system in the event of power loss.
As part of this policy, CLIA cruise lines are to establish procedures intended to maintain adequate head pressure in the water mist system while discharging, in the event multiple adjacent detectors or nozzles are activated, such as through the use of smoke control barriers, isolation valves, or similar measures.
