Dimethylhydrazine

“…All currently available standards and guidelines are shown in Table 47. Frawley (1964) provided a summary of data relevant for the derivation of emergency exposure levels (EELs) for 1,1-dimethylhydrazine. The EELs are Numeric values for AEGL-1 are not recommended because (1) the lack of available data, (2) data indicate that toxic effects may occur at or below the odor threshold, (3) the inadequate margin of safety that exists between the derived AEGL-1 and the AEGL-2, or (4) the derived AEGL-1 is greater than the AEGL-2.…”
