d.
Novec 1230 and FM-200 are clean agent fire suppression compounds made of synthetic chemicals in liquid form and are converted to gas in the discharge process. Both work to extinguish fire and prevent re-ignition by removing the necessary elements of combustion – heat.
Unlike Novec 1230 and FM-200, Inert is a gaseous clean agent made up of a mixture of various inert type gases. Inert gas systems work by reducing the oxygen in the space to below that required for combustion.
