 The European Commission’s Scientific Committee on Occupational Exposure Limits (SCOEL) places hydrazine in carcinogen “group B—a genotoxic carcinogen”.The genotoxic mechanism the committee cited references hydrazine's reaction with endogenous formaldehyde and formation of a DNA-methylating agent.In the event of a hydrazine exposure-related emergency, NIOSH recommends removing contaminated clothing immediately, washing skin with soap and water, and for eye exposure removing contact lenses and flushing eyes with water for at least 15 minutes.
