Safety Profile
Human poison by inhalation. An eye irritant. See also FLUORIDES, CHLORINE, and FLUORINE. Spontaneously flammable. A powerful oxidant whch may react violently with oxidzable materials. A rocket propellant. Explosive reaction with water, bis (trifluoromethyl) sulfide or -disulfide, polychlorotrifluoroethylene, trifluoromethanesulfenyl chloride, and other hydrogencontaining materials (e.g., ammonia, coal gas, hydrogen, hydrogen sulfide, methane, acetic acid, benzene, ether, cotton, paper, wood). Forms shock-sensitive explosive mixtures with highly chlorinated compounds (e.g., carbon tetrachloride), nitroaryl compounds (e.g., trinitrotoluene, hexanitrobiphenyl, hexanitrodiphenyl amine, hexanitrodiphenyl sulfide, hexanitrobphenyl ether). Reaction with ammonium fluoride or ammonium hydrogen fluoride forms explosive gaseous products. materials, iodine, finely dvided refractory materials (e.g., asbestos, glass wool, sand, tungsten carbide), fluorinated polymers (with flowing trifluoride). sulfuric), chromium trioxide, ruthenium, selenium tetrafluoride (above 106℃), metals, metal oxides, metal salts, nonmetals, nonmetal salts, organic matter, glass wool, acetic acid, Al, Sb, As, Cu, Ir, Fe, Pb, Mg, Mo, Os, P, Ir, Rh, Se, Si, Ag, Na, S, Te, Sn, W, Zn, oxides, CO, graphite, HgI2, HNO3, Ignition on contact with boron-containing Violent reaction with acids (e.g., nitric or K2CO3, KI, rubber, AgN3, AgNO3, NaOH, V2P5, wo3.
