UK technology for the constant monitoring
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 :
22.214.171.124 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.
Monitoring Gaseous Extinguishing Systems
- The reality is that gaseous systems are checked for contents annually because they are pressurised and anything that is dynamic offers risk of loss of contents , but this fails to deal with the probability of discharge or leakage for the 364 days per annum in the interim between certification checks.
- We manufacture the portable liquid level indicator Portalevel™ used by fire technicians for the contents checking of CO2, old Halons, FM-200™ and NOVEC™ 1230.
- Portalevel™ liquid level indicator readings are then converted to agent weight readings via Portasteele™ Calculator – the world’s first
- Constant monitoring of the contents of gaseous systems are now enabled via the 24/7 system Permalevel™ Multiplex, but the fire industry is highly resistant to using technology to constantly monitor the pressurised systems which it installs.
Monitoring Room Integrity
- Coupled to this is a lack Room Integrity testing after the gaseous system has been installed.
- As buildings age or their internal use is changed leak sites develop.
- If the gas cannot be “held” in the room on discharge during a fire event the probability of its suppression diminishes in direct proportion to the size of the leak sites.
- Portascanner™ 520 is a hand-held product designed to identify leak-sites in Protected Spaces. it is simple to create from this the means to constantly monitor room integrity as the building ages or its internal use changes and leak sites develop.
We design the UK technology which enables the continuous monitoring of both.
