◆Introduction:
Noah®5112, REACH registered FK-5-1-12 is a next-generation halon alternative offering outstanding performance, a large margin of safety, and an excellent environmental profile.
• Zero ozone depletion potential
• 5-day atmospheric lifetime
• Global warming potential <1
• Large margin of safety for occupied spaces
Noah®5112, REACH registered FK-5-1-12 Fire Protection Fluid is based on a proprietary chemical from 3M called a fluroroketone. The full chemical name for this compound is dodecafluoro-2-methylpentan-3-one. Its ASHRAE nomenclature – the way it is designated in the NFPA and ISO 14520 clean agent standards – is FK-5-1-12. Noah®5112, REACH registered FK-5-1-12 fluid offers a unique combination of safety, low environmental impact and extinguishing performance, making it the only chemical halon replacement to offer a viable, long-term, environmentally sustainable technology for special hazards fire protection.

◆Design Concentrations
Like other halocarbon halon alternatives, Noah®5112 extinguishes principally by removing heat from the fire. Upon discharge, Noah®5112 fluid creates a gaseous mixture with air. This agent/air mixture has a heat capacity much larger than that of air alone. A higher heat capacity means that this gas mixture will absorb more energy (heat) for each degree of temperature change it experiences. At the system design concentration, the agent/air mixture absorbs sufficient heat to upset the conditions required for combustion to occur. The amount of heat the fire loses to the surroundings is increased by the presence of the agent. This causes the combustion zone to cool to the point that the fire extinguishes. Noah®5112 fluid has the highest heat capacity of the commercially available halon alternatives resulting in the lowest extinguishing concentrations for a given fuel. The design concentration for Class A combustibles is a minimum of 4.5 vol% for designs based on UL 2166 in the USA. Different minimum design concentrations may be required in other countries based on local approvals.
◆Environmental Properties
Once emitted into the environment, there are a number of ways for organic compounds to be removed from the atmosphere. Studies conducted on Noah®5112 fluid have determined the atmospheric loss rates via these removal mechanisms and the effect on the atmospheric lifetime of this compound. The very low water solubility of Noah®5112 fluid and the low degree to which it partitions into liquid water was found to preclude atmospheric hydrolysis from being a meaningful removal mechanism. The principal atmospheric sink for Noah®5112 agent is photolysis. It exhibits strong absorption of energy at near UV wavelengths, resulting in a very short atmospheric lifetime. The rate of photolysis under atmospheric conditions and the mechanism of decomposition of this compound have been investigated by two different research groups1,2. The photolysis rate of the fluoroketone leads to an atmospheric lifetime of approximately 1 week, which is consistent with the Noah study that found the atmospheric lifetime of Noah®5112 fluid to be on the order of 5 days.
◆ Main application:
1. Noah®5112 is a green environmental, efficient and clean fire extinguishing agent, can be widely used all over the regional or local regional fire extinguishing system and portable fire extinguisher, especially applicable to electronic control center, computer room, transformer room, power distribution cabinets, wind power equipment room, energy storage power station, high precision instrument, museum, data processing center, ship control rooms, new energy vehicle lithium battery protection and other occasions of fire protection.
2. It can be used as coolant for electronic equipment and protection gas for light metal smelting. It can also be used to replace sulfur hexafluoride for transformer protection.
