Lower Explosion Limit % by volume (in air): >1.1 Unusual Fire and Explosion Hazards: None SECTION 6 – HEALTH HAZARDS Exposure Limit(s): Ethylene Glycol, Monobutyl Ether: 25 PPM TWA (skin), OSHA, and ACGIH Ethylene Glycol: 100 mg/m3 (39.4 PPM) Ceiling, Aerosol, ACGIH 127 mg/m3 (50 PPM) Ceiling, Vapor and Mist, OSHA Union Carbide recommendation: 100 mg/m3 (39.4 PPM) Ceiling, Aerosol and Vapor EFFECTS OF ACUTE OVEREXPOSURE: Swallowing: Moderately toxic. May cause headache, dizziness, incoordination, nausea, vomiting, diarrhea, and general weakness. Ingestion of significant quantities may result in red blood cell hemolysis. Skin Absorption: Effects may include those described for swallowing. Moderately toxic. Prolonged or widespread contact may result in the absorption of potentially harmful amounts of material. Inhalation: High concentrations of vapor cause irritation of the respiratory tract, experienced as nasal discomfort and discharge, with chest pain and coughing. Headache, nausea, vomiting, dizziness, and drowsiness may occur. Skin Contact: Brief contact may cause slight irritation with itching and local redness. Prolonged contact may cause more severe irritation, with discomfort or pain, local redness and swelling, and possible tissue destruction. Eye Contact: Causes severe irritation experienced as discomfort or pain, excess blinking and tear production, with marked excess redness and swelling of the conjunctiva. Effects of repeated overexposure No adverse effects anticipated from available information. Other health hazards Has caused red blood cell hemolysis in laboratory animals and secondary injury to the kidney and liver. However, humans appear to be resistant to this effect. Medical conditions aggravated by overexposure: Skin contact may aggravate an existing dermatitis. Additional Toxicity Information: Results of studies in laboratory animals indicate that Ethylene Glycol Monobutyl Ether does not cause specific toxic effects on development of offspring. This material does not cause increases in malformations even at dosages which produce clear evidence of maternal toxicity. The types of developmental effects noted at maternally toxic levels are consistent with those which might be anticipated in offspring from mothers suffering from toxic effects or stress as a result of chemical exposure. In laboratory animal studies, large doses of Ethylene Glycol Monobutyl Ether have caused injury to liver and kidneys. This injury is believed to be secondary to red blood cell hemolysis, a known effect of this material in rodents. Humans are resistant to the hemolytic effects of Ethylene Glycol Monobutyl Ether and therefore the kidney and liver injury noted in animal studies is not considered relevant to human health hazard evaluation.
