Formed in 1995 by EPA, several other federal and state agencies, and several private organizations, the National Advisory Committee on Acute Exposure Guideline Levels for Hazardous Substances (referred to as the NAC) develops, reviews, and approves acute exposure guideline levels (AEGLs) for up to 400 extremely hazardous substances (EHSs). AEGLs have a broad array of potential applications for federal, state, and local governments and for the private sector. They are necessary for prevention and emergency-response planning for potential releases of EHSs, either from accidents or as a result of terrorist activities. This report includes an assessment of the NAC's draft AEGLs documents for the following 25 chemicals: allyl alcohol, bis-chloromethyl ether, chloromethyl methyl ether, bromine pentafluoride, bromine trifluoride, chlorine pentafluoride, carbon tetrachloride, chloroform, chlorosilanes (26 selected compounds), epichlorohydrin, formaldehyde, hydrogen bromide, hydrogen iodide, methyl bromide, methyl chloride, nitric acid, nitric oxide, nitrogen dioxide, nitrogen tetroxide, piperidine, titanium tetrachloride, toluene, trimethylbenzenes (1,2,4-; 1,2,5-;and 1,3,5-TMB), vinyl acetate monomer, and vinyl chloride.
