In four hour inhalation studies, rats and mice show central nervous system depression. Oral and intraperitoneal doses at near lethal levels injure the liver and kidneys. Workers exposed in an accident to 50-500 ppm for one hour experienced weakness, sweating, headache, and vomiting. One of these workers lost consciousness for 20 minutes. [ACGIH] See "THIOLS."
