A very diversified art has been developed utilizing certain metal fluorides, inorganic fluorides, halogen fluoride, or electrochemical cells as media for fluorination. The more important approaches which have been developed to produce fluorocarbons and yet avoid the great reactivity of elemental fluorine are ... 

DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE Poison by inhalation. A corrosive irritant to the eyes, skin, and mucous membranes. With the appropriate conditions it undergoes hazardous reactions with formic acid, hydrogen fluoride, inorganic bases, iodides, metals, methyl hydroperoxide, oxidants (e.g., bromine, pentafluoride, chlorine trifluoride, perchloric acid, oxygen difluoride, hydrogen peroxide), 3-propynol, water. When heated to decomposition it emits toxic fumes of POx.
