Misunderstanding exists across parts of Shipping regarding the application of a part of the IMO SOLAS FSS Code; the need for crew to test the contents of their CO2, FM-200® & Novec 1230 gas suppression system Gaseous Extinguishing Systems in between the periodic inspection, maintenance and certification intervals. These periodic inspections are conducted annually or biennially, and only by an Accredited Service Agent i.e. an external Marine Servicing Company. The reason IMO requires crew to test for contents in-between these is that the “ship sails alone”; it must act as its own emergency fire service.
IMO SOLAS FSS Code Chapter 5 Fixed gas fire extinguishing systems :
188.8.131.52 Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers. It shall not be necessary to move the containers completely from their fixing positions for this purpose.
ISO 14520-1 : 2015 Gaseous Extinguishing Systems and some key extracts from it follow for your general interest :
The assumptions in these are that gaseous extinguishing/suppression systems must be checked for 5% loss of contents against the risk of leakage or accidental discharge. The regulations that underpin the pursuit of them support their leak identification every 6 months.
