Fire is one of the calamities that can cause untold loss of life and property. Hence, over the years, humankind has developed various increasingly effective ways of extinguishing or suppressing fires, in order to safeguard human lives, property and assets, and the environment. The latest and most popular systems are known as ‘clean agent fire suppression systems’.
Clean agent fire suppression systems use a ‘clean agent’ to extinguish fires. A clean agent is an electrically non-conductive, volatile, or gaseous fire extinguishing agent that leaves no residue upon evaporation. Clean agent fire suppression systems use inert gases or chemicals stored in containers, which extinguish fire when discharged. From a sustainable point of view as well, clean agents are preferable for maximum use as they are substantially more environment-friendly than all other options.
How do clean agent fire suppression systems work?
Essentially, a fire requires three components: heat, oxygen, and a fuel source. If any of these is not present or gets cut off, the fire will be suppressed. Clean agents eliminate either the heat or the oxygen to put out the fire. There are three main types of Clean Agent Systems:
FM 200
Inert Gas:
CO2
INERGEN
FK5112
Among these, FK5112 based systems are gaining increasing demand and popularity worldwide. Let us delve a bit deeper into what makes these systems so special!
u What is FK5112?
FK5112, scientifically known as 1,1,1,2,2,4,5,5,5-Nonafluoro-4-(Trifluoromethyl)-3-Pentanone is a fluorinated ketone. It is used as a clean agent in fire suppression systems and has fast emerged as one of the most popular Clean Agent options globally.
u How does it work?
It is used as a gaseous suppression agent in places where water or CO2 based extinguishers would be impractical. FK5112 is stored as a non-toxic, colorless liquid which converts into a gas when discharged and removes the heat from the fire, thereby extinguishing it. Usually employed in fixed fire safety systems, FK5112 is also used in portable extinguishers for specialized applications.
Once expelled into the environment, FK5112 exhibits strong absorption of energy at near UV wavelengths, resulting in a very short atmospheric lifetime. Thus, photolysis is the main atmospheric sink for the compound, resulting in the gas getting completely dispersed within 5 days to a week. Being a clean agent, of course, it does not leave any residue, damage any assets or harm the environment in any way.
u How is it different from other Clean Agent?
l Environmental
FK5112 is considered the best, most environment-friendly clean agent, having zero Ozone Depletion Potential and a Global Warming Potential of just 1! This means that it has next to no effect on the environment, and does not contribute to climate change. Hence it is an excellent replacement for the old HFC systems which were harmful to the ozone layer. This makes it preferable over the HFC-227ea system, which has slightly higher ozone depletion potential.
l Occupant Safety
FK5112 agent has no effect on the health of the occupants in any space. Unlike CO2 systems which can cause breathing trouble to occupants by lowering the oxygen levels in the surroundings to put out the fire, FK5112 simply removes the heat from the surroundings, suppressing the fire within seconds. Hence, it is completely safe for occupants and can be used in areas with high occupant density.
l Asset Protection
FK5112 is non-toxic, non-corrosive, and leaves no residue upon action. This makes it, along with the INERGEN system, one of the safest and cleanest agents to be used for extinguishing fires.
Additionally, it is also one of the most electrically non-conductive materials to be used as a clean agent. Hence, it is especially useful in facilities having a large number of electronic and electrical components, such as data centers, server rooms, race cars, and industrial facilities.
l Convenience
Not only is FK5112 a clean agent, it is extremely fast-acting as compared to INERGEN or CO2; hence, it severely limits the amount of damage the fire can do to the surroundings. It is also extremely effective in small quantities, thus requiring less space for storage. All these factors make it a convenient, sustainable and safe clean agent fire suppression system.
u When and where is it used?
Considering the above factors, it is no wonder that the FK5112-based clean agent fire suppression systems have a widespread application. They can be used for occupied as well as non-occupied places. They are recommended for use in facilities that require maximum preservation of assets. Some of the facilities where FK5112 systems are recommended are:
Museums and art galleries
Valuable cargo warehouses and shipments
Server rooms
Data centers
Electronic areas with very sensitive or irreplaceable equipment
Telecommunication and switching centers
Power generation and transmission facilities
Industrial facilities
Military facilities and marine engine rooms
Racing cars
Seafaring merchant, defense, and recreation vessels
Airplanes
u What about FK5112 price
FK5112 price though a little higher than other clean agent, but it is most cost effective. As it is safest and most efficient. Moreover, during these years, FK5112 price has also come down a lot, thus make it more welcomed in most places due to its superior and various advantage.
