Exposure guidelines

Although the CW agents and TICs are very toxic, various federal agencies have developed guidelines for possible exposures to determine safe concentrations and times for various operations for each chemical. These are based on work and exposures civilians and mihtary personnel may be required to experience in a toxic environment. There are different exposure times for various activities and therefore for various agencies. Eor example, the Occupational Safety and Health Administration (OSHA) sets permissible exposure levels (PELs) for people who might be exposed [Pg.666]

ERPG-2 reversible adverse effects that will not impair a person s ability to take protective action, or [Pg.667]

The ERPGs, as of 2006, can be found at the AlHA Web site, http //www.aiha.org/ldocuments/ Committees /ERP-erpglevels. pdf. [Pg.667]

Acute Exposure Guideline Levels (AEGLs) are developed by the National Research Council s Committee on Toxicology and, unlike the ERPGs, are meant for the general population. The dehnitions are as follows [Pg.667]

AEGL-3 The airborne concentration of a substance above which it is predicted that the general population, including susceptible individuals, could experience life-threatening health effects or death. [Pg.667]

The health and safety professional recognizes that air contaminants may exist as gases, dust, fumes, mist, or vapors in the workplace air. In evaluating the degree of exposure, the measured concentration of the air contaminant is compared to limits or exposure guidelines. [Pg.180]

Personal Protective Equipment. Personal protective and emergency safety equipment should not be reHed on as the primary protection from aHyl chloride. Prevention of exposure should be considered the preferred precautionary measure. Where the exposure guideline may be gready exceeded, an approved positive-pressure air suppHed or self-contained breathing apparatus with fuH facepiece should be used (51). [Pg.35]

ACGIH maintains annual editions of the TLVs and BEIs which are used worldwide as a guide for evaluation and control of workplace exposures to chemical substances and physical agents. Threshold Limit Value (TLV ) occupational exposure guidelines are recommended for more than 700 chemical substances and physical agents. There are more than 50 Biological Exposure Indices (BEIs ) that cover more than 80 chemical substances. [Pg.313]

Variations in radiation doses to individuals within exposed populations also occur. Based upon previous exposures of people to Pu and Sr in fallout and exposures of laboratory animals to Ce, the dispersion of individual doses in a population is expected to be significant and should be considered in the formulation of population exposure guidelines.

Using the 1993 NRC guidelines report, the National Advisory Committee (NAC) on Acute Exposure Guideline Levels for Hazardous Substances—consisting of members from EPA, the Department of Defense (DOD), the Department of Energy (DOE), the Department of Transportation, other federal and state governments, the chemical industry, academia, and other organiza...

In 1998, EPA and DOD requested that the NRC independently review the AEGLs developed by NAC. In response to that request, the NRC organized within its Committee on Toxicology the Subcommittee on Acute Exposure Guideline Levels, which prepared this report. This report is the first volume in the series Acute Exposure Guideline Levels for Selected Airborne Chemicals. It reviews the appropriateness of the AEGLs for four chemicals for their scientific validity, completeness, and consistency with the NRC guideline reports. [Pg.13]
