Health and Safety Guide: 1, 3-Dichloropropene, 1, 2-Diciiloropropane and Mixtures

This document summarizes authoritative guidance on the health, environmental, and safety aspects of 1,3-dichloropropene, 1,2-dichloropropane, and their fumigant mixtures, outlining identity, properties, analytical methods, production, and agricultural uses. It summarizes environmental fate, noting rapid volatilization and hydrolysis for 1,3-dichloropropene, greater soil persistence and groundwater contamination potential for 1,2-dichloropropane, and limited bioaccumulation for all constituents. It evaluates kinetics, toxicology, and ecotoxicity, identifies primary target organs, and reports occupational exposure scenarios, with general-population risk typically negligible except where groundwater is impacted. It provides practical measures for prevention, first aid, firefighting, storage, transport, spillage response, and disposal, and compiles regulatory classifications, exposure limits, and labelling requirements.
