Key value for chemical safety assessment

Additional information

Described effects after repeated exposure are the same as after single exposure (see STOT SE). Other described effects are considered to be secondary effects, for example hemosiderosis in the speen is a result of hemolysis. Thus, methylhydrazine is not classified for repeated dose toxicity.

For details see:

- ACGIH 2001: Methylhydrazine TLV-TWA

- MAK (german "maximum concentration value at the workplace") derivation of 1988.

Justification for classification or non-classification
