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 Novec 1230 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 Novec 1230 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 Novec 1230 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 3M study that found the atmospheric lifetime of Novec 1230 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. Fluids from the 3M Novec family have been used as a full-immersion fluid in a proof of concept data center cooling system by Intel and SGI.[2] As it boils off easily, it is used with a condensing loop running cold water.

3M produces Novec 1230 Fire Protection Fluid.
