Safety Description:Human poison by ingestion and intramuscular routes. Experimental poison by ingestion, skin contact, intraperitoneal, intramuscular, subcutaneous, parenteral, and intravenous routes. Human systemic effects by ingestion, intramuscular, and parenteral routes: paresthesia, wakefulness, excitement, muscle contraction or spasticity, nausea or vomiting and other gastrointestinal changes. The action is similar to that of parathion: causing an irreversible inhibition of the cholinesterase molecules and the consequent accumulation of large amounts of acetylcholine. Small doses at frequent intervals are largely additive. When heated to decomposition it emits toxic fumes of PO_x. See also PARATHION.
