Introduction to Clean Agents

Commonly Used Clean Agents

FK-5-1-12 (Novec1230)

FK-5-1-12, dodecafluoro-2-methylpentan-3-one, is produced under the trade name of NovecTM 1230 by 3M Corporation. It is classified as a halocarbon clean agent and is employed at design concentrations typically ranging from 5.3% to 6.0% by volume. This concentration range corresponds to an agent mass requirement of 4.8 to 5.5 lb/100 ft3 of protected volume (77.5 to 88.4 kg/100m3 of protected volume). It is stored as a liquid in the discharge cylinder and is super-pressurized to either 360 psig (24.8 bar) or 600 psig (42 bar) with nitrogen. Under these conditions, FK-5-1-12 has a maximum cylinder fill density of 90 lb/ft3 (1441 kg/m3). However, FK-5-1-12 is rarely stored above a fill density of 70 lb/ft3 (1121 kg/m3), due to the need for the extra ullage space to aid in the discharge of the agent. This lower fill density corresponds to an agent storage volume requirement of 0.069 to 0.079 ft3/100 ft3 of protected space (68.8 to 78.8 L/100 m3 of protected space).
 
It is nontoxic, odorless and colorless and is not suspected of contributing to stratospheric ozone depletionThe molecule does not contain any bromine or chlorine atoms, which are suspected of causing stratospheric ozone depletion..

FK-5-1-12 has an estimated atmospheric lifetime of 0.014 years and a GWP of 1 (GWP of CO2=1). Source: United Nations Framework Convention on Climate Change (UNFCCC).

Exposure to FK-5-1-12 can cause cardiac sensitization, similarly to Halon 1301, with the highest tested concentration of 10.0 % by volume for which there was no observable adverse effect (NOAEL).
