Technical Guide 230 - Environmental Health Risk Assessment and Chemical Exposure Guidelines for Deployed Military Personnel
TG230 provides a standard methodology for characterizing chemical exposure health risks at deployment locations in a manner that is consistent with military risk management doctrine. Health-based, military exposure guidelines (MEGs) for chemicals are presented for air, water, and soil associated with various deployment exposure scenarios.

Microorganisms (and TG316 Supplements)
TG316 provides a general methodology framework for assessing aerosolized microbial hazards and characterize risk as a result of environmental, occupational, or intentional exposures. The TG outlines the considerations and steps necessary to complete a microbial risk assessment. It is designed to be used as a preplanning or post-event tool. Stand-alone TG 316 supplements provide specific information and risk assessment tools, to include biological military exposure guidelines (BMEGs).
Associated Documents: TG 316 and numerous TG 316 supplements have been published with a restricted distribution. (Password protected - AKO)
