Extremely hazardous substances (EHSs) can be released accidentally as a result of chemical spills, industrial explosions, and other accidents, or intentionally through terrorist activities. Workers and residents in communities surrounding industrial facilities where EHSs are manufactured, used, or stored and in communities along the nation's railways and highways are potentially at risk of being exposed to airborne EHSs during accidental or intentional releases.
To help understand the risk involved with EHSs, the National Advisory Committee (NAC) on Acute Exposure Guideline Levels for Hazardous Substances developed Acute Exposure Guideline Levels (AEGLs) for approximately 200 EHSs.
The present volume is the sixteenth interim report evaluating the AEGLs. It summarizes conclusions and recommendations for improving NAC's AEGL documents for 26 chemicals. The report also summarizes the committee's conclusions and recommendations for improving the Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Substances published in 2001.
