    Odor threshold

    • Odor Threshold Low: 1.7 [mmHg]. [NRC 1985] Odor threshold from CHEMINFO
    • 1.75 mg/cu m (low); 5.25 mg/cu m (high)
    • The warning properties (irritation & odor) of the hydrazines are probably sufficient to prevent acute poisoning from short exposures. However, in view of the chronic toxicity properties, the warning properties should not be considered adequate for prolonged exposures. /Hydrazines/
