Phosphine is a colourless, flammable, very toxic gas compound with the chemical formula PH₃, classed as a pnictogen hydride. Pure phosphine is odourless, but technical grade samples have a highly unpleasant odour like rotting fish
Phosphine is used in the semiconductor industry to introduce phosphorus into silicon crystals . It is also used as a fumigant, a polymerization initiator and as an intermediate for the preparation of several flame retardants.
Phosphine (PH3) is extremely Toxic. The Immediately Dangerous to Life or Health level is 50 ppm. Overexposure to phosphine gas causes nausea, vomiting, abdominal pain, diarrhea, thirst, chest tightness, dyspnea (breathing difficulty), muscle pain, chills, stupor or syncope, and pulmonary edema.
