The median lethal dose of oral exposure in rat is 85 mg/kg and that of dermal is 390 mg/kg.。It is a weak acetylcholinesterase inhibitor. It is taken by not only oral and inhalation but skin and it causes toxic symptoms peculiar to organophosphorus compounds such as miosis, hypersalivation, hyperhidrosis, chest pressure, pulmonary edema and fecal incontinence. It is flammable and decomposes to toxic gases such as phosphorus oxides, sulfur oxides and nitrogen oxides. It is harmful especially to water creatures.
