It is absorbed through the skin; a severe eye irritant; [CSH, p. 291] It is mainly an irritant, but it can cause severe contact dermatitis due to prolonged contact. [Kanerva, p. 1816] Experimental animals experience lethargy and respiratory difficulty after inhalation. [HSDB] Some animal studies found fetal loss and birth defects after high doses during early pregnancy. [Frazier, p. 345] NMP is a cyclic amide used as... Inhalation of hot vapors can irritate nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Repeated and prolonged skin contact produces a mild, transient irritation. (USCG, 1999) Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire. (USCG, 1999) |
