In keeping with a congressional mandate (Public Law 104-484) and the Chemical Weapons Convention, the United States is currently destroying its chemical weapons stockpile. The Army must ensure that the chemical demilitarization workforce is protected from the risks of exposure to hazardous chemicals during disposal operations and during and after facility closure. Good industrial practices developed in the chemical and nuclear energy industries and other operations that involve the processing of hazardous materials include workplace monitoring of hazardous species and a systematic occupational health program for monitoring workers’ activities and health. In this report, the National Research Council Committee on Review and Evaluation of the Army Chemical Stockpile Disposal Program examines the methods and systems used at JACADS and TOCDF, the two operational facilities, to monitor the concentrations of airborne and condensed-phase chemical agents, agent breakdown products, and other substances of concern. The committee also reviews the occupational health programs at these sites, including their industrial hygiene and occupational medicine components. Finally, it evaluates the nature, quality, and utility of records of workplace chemical monitoring and occupational health programs.
