Safety Description:Confirmed carcinogen. Mildly toxic by inhalation. Can act as an asphyxiant and may have other toxic properties. The gas is flammable when exposed to heat or flame. The inhibited monomer will explode if ignited. Explosive in the form of vapor when exposed to heat or flame. Will explode at pressures above 2.7 bar if limonene inhibitor is not added. Iodine pentafluoride depletes the limonene inhibitor and then causes explosive polymerization of the monomer. Mixtures with hexafluoropropene and air form an explosive peroxide. Reacts violently with SO₃; air; difluoromethylene dihypofluorite; dioxygen difluoride; iodine pentafluoride; oxygen. When heated to decomposition it emits highly toxic fumes of F⁻.
