EMERGENCY EXPOSURE LIMITS: NITROGEN DIOXIDE; 1,1-DIMETHYLHYDRAZINE; 1,1,1-TRICHLOROETHANE.

Abstract Here are presented the first three of a new series of guides to Emergency Exposure Limits. These Limits are intended to give guidance to industrial hygienists in the management of single, brief exposures to air-borne contaminants in the working environment. Emergency Exposure Limits for nitrogen dioxide, 1,1-dlmethyl-hydrazine, and 1,1,1-trichloroethane are presented with supporting information.
