◆ Introduction:
Noah®5112 fire safety and protection agent, which is 1,1,1,2,2,4,5,5,5-NONAFLUORO-4-(TRIFLUOROMETHYL)-3-PENTANONE is a fluorinated ketone and the structural formula CF3CF2C(=O)CF(CF3)2, a fully-fluorinated analog of ethyl isopropyl ketone.
It does not deplete ozone (ODP 0) and has a global warming potential of less than 1. 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 fire safety and protection agent 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 ofNoah®5112 fire safety and protection agent 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 groups. 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.
It is used as gaseous fire suppression agent in scenarios where water-based fire suppression (for example, from a fire sprinkler) would be impractical or where it could damage expensive equipment or property, such as museums, server rooms, banks, clean rooms and hospitals. It can be used in both total/partial/localized flooding systems, and directional spray type applications; it is also used in portable extinguishers for specialized applications.
◆Toxicity Profile
Noah carefully and thoroughly characterizes the toxicity of new candidate materials early in the development process. These early studies and the subsequent studies conducted by independent laboratories demonstrate that Noah®5112 fluid is very low in both acute and chronic toxicity. The No Observed Adverse Effect Level (NOAEL) for all end-points of acute toxicity is 10% based on a cardiac sensitization study and a 4-hour acute inhalation study.
