To guide mission planning, military decision makers need information on the health risks of potential exposures to individual soldiers and their potential impact on mission operations. To help with the assessment of chemical hazards, the U.S. Army Center for Health Promotion and Preventive Medicine developed three technical guides for characterizing chemicals in terms of their risks to the mission and to the health of the force. The report reviews these guides for their scientific validity and conformance with current risk-assessment practices. The report finds that the military exposure guidelines are appropriate (with some modification) for providing force health protection, but that for assessing mission risk, a new set of exposure guidelines is needed that predict concentrations at which health effects would degrade the performance of enough soldiers to hinder mission accomplishment.
