Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air ( WebPhosphine TWA 0.05 ppm American Conference of Governmental Industrial Hygienists Phosphine TWA 0.3 ppm 0.4 mg/m3 Occupational Safety and Health Administration - Table Z-1 Limits for Air Contaminants The value in mg/m3 is approximate.
