Simply put, the ‘ungoverned space’ is the area in the fire industry where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety. Coltraco repeatedly push for this life-threatening issue to be dealt with, with specific regard to loss of contents in fixed fire extinguishing systems.
Gaseous extinguishing systems protect urgently important infrastructure against special hazards, fundamental for the safeguarding of critical facilities.
Although many in the fire industry work towards meeting better standards, in their experience, Coltraco have numerous concerning anecdotes of non-compliance: systems portrayed and installed by contractors as NOVEC™ 1230 but filled with sand or water… room integrity testing with questionable results and with the room integrity remaining un-monitored after testing… liquefied extinguishants being confused by installers with Inert gas systems… service engineers asking how to test the liquid level indicator in powder… the list goes on.
Coupled with these anecdotes, currently the regulations are not extensive enough to deal with the risks presented in gaseous systems. In 18.104.22.168 the regulations explains that the storage container contents shall be checked at least every six months as follows. : a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced. b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced. Essentially, it is known in regulations that the gaseous systems leak and need to be maintained. Given that the gaseous systems are designed specifically to the individual need of that room, building e.t.c, a 5% loss of agent may mean that they would not fully extinguish the fire.
Can one annual check account for the probability of discharge and leakage for the other 364 days of the year between certification checks?
The neglect of continuous monitoring - of the fundamental protection provided by the gaseous extinguishing systems - is to the peril of the lives of occupants of the premises and at the risk of crippling financial and reputational loss to the facility comprising the critical infrastructure.
The examples of where continuous monitoring are essential are many, extensive and varied. If you protect critical infrastructure, then this article applies to you.
However to exemplify the integral nature of continuous monitoring; incidents in nuclear power plants around the world have continued to demonstrate the vulnerability of safety systems to fire and its effects. The potential danger from an accident at a nuclear power plant is exposure to radiation to the people in the vicinity of the plume from the cloud and particles deposited on the ground, inhalation of radioactive materials and ingestion of radioactive materials. The International Atomic Energy Authority state clearly in the Fire Safety in the Operation of Nuclear Power Plants standards that the effects of a single failure in fire safety systems, such a system not performing its required function, can be detrimental. With fires at nuclear power plants still occurring, such as the technical issue which led to a blast at the 2017 power plant at Flamanville, deemed “very serious” by industry experts, the call for advanced technology is of most importance.
Focused on continued advancement of safety technology, Coltraco have now developed the Permalevel® Multiplex, a fixed fire suppression monitoring device, designed for permanent contents verification. The Permalevel® Multiplex is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire.
