In this process, organic feedstocks are dispersed in liquid, anhydrous hydrogen fluoride, and an electric current is passed through the solution, causing the hydrogen atoms on the molecule to be replaced with fluorine.

Tasks with moderate exposure potential (short term sampling from taps or drums, `and some maintenance tasks) are performed using full face air-purifying respirators with organic. vapor cartridges and P100 prefilters. `Hand protection: All tasks identifiedashaving potential for hand contact require neoprene (Scorpio) or nitrile industrial gloves. Body protection: Exposuresignificanttasks use one or two-piece PVC suits. Aprons may be `worn for some low exposure potential tasks such as sampling.
