Health Factors

Carcinogenic Classification:

International Agency for Research on Cancer (IARC) carcinogenic classification: Group 3, not classifiable as to its carcinogenicity to humans [381 KB PDF, 171 pages]

Potential Symptoms: Irritation and corrosion of eyes, skin, respiratory system; cough, sore throat, shortness of breath, burning sensation, labored breathing, pulmonary edema (may be delayed); eye, skin burns, pain, blindness (from contact with liquid); skin sensitization. INGES ACUTE: burning sensation; weakness; abdominal cramps, diarrhea; shock; corrosive; unconsciousness

Health Effects: Irritation-Eyes, Nose, Throat, Skin---Marked (HE14); Respiratory effects---pulmonary edema (HE11)

Affected organs: Eyes, skin, respiratory system

Note: Metabolized to carbon dioxide and acetyl coenzyme A in a variety of mammalian tissues. There is no OSHA PEL, but some states have standards (see Pohanish, 2002).
