| Use Information |
1,1-Dimethylhydrazine is primarily used as a high-energy fuel in military applications and as a rocket propellant and fuel for thrusters. Acute (short-term) inhalation exposure of humans to 1,1-dimethylhydrazine results in nose and throat irritation, mild conjunctivitis, nausea, and vomiting. It is also highly corrosive and irritating to the skin, eyes, and mucous membranes. Liver damage in humans may occur from chronic (long-term) exposure to 1,1-dimethylhydrazine. No information is available on the reproductive, developmental, or carcinogenic effects of 1,1-dimethylhydrazine in humans. Carcinogenic effects have been observed in animals exposed to 1,1-dimethylhydrazine by inhalation and orally, predominantly to the lung and liver. EPA has not classified 1,1-dimethylhydrazine for potential carcinogenicity. The International Agency for Research on Cancer (IARC) has classified 1,1-dimethylhydrazine as a Group 2B, the chemical is possibly carcinogenic to humans. |
