Table 4: Protective Action Criteria (PAC) Rev 25 based on applicable 60-minute AEGLs, ERPGs, or TEELs. Values are presented in mg/m3. August 2009 Table 4 is an alphabetical listing of the chemicals in the PAC data set. It provides Chemical Abstract Service Registry Numbers (CASRNs)1, PAC values, and technical information on the source of the PAC values. Table 4 presents all values for TEEL-0, PAC-1, PAC-2, and PAC-3 in mg/m3. The conversion of ppm to mg/m3 is calculated assuming 25 ºC and 760 mm Hg. The columns presented in Table 4 provide the following information: Heading Definition No. The ordered numbering of the chemicals as they appear in this alphabetical listing. Chemical Name The chemical name given to the PAC Development Team. CASRN The Chemical Abstract Service Registry Number for this chemical. TEEL-0 This is the threshold concentration below which most people will experience no adverse health effects. This PAC is always based on TEEL-0 because AEGL-0 or ERPG-0 values do not exist. PAC-1 Based on the applicable AEGL-1, ERPG-1, or TEEL-1 value. PAC-2 Based on the applicable AEGL-2, ERPG-2, or TEEL-2 value. PAC-3 Based on the applicable AEGL-3, ERPG-3, or TEEL-3 value. Source of PACs: Technical comments provided by the PAC development team that TEEL-0, PAC-1, indicate the source of the data used to derive PAC values. Future efforts PAC-2, PAC-3 are directed at reviewing, revising, and enhancing this information. Chemicals for which AEGLs are available have their chemical name, CASRN, and AEGL values displayed in a bolded and larger font. Chemicals for which ERPGs are available, but not AEGLs, have their chemical name, CASRN, and ERPG values displayed in a bolded font. Chemicals for which TEELs are available, but not AEGLs or ERPGs, have their chemical name, CASRN, and values displayed using a regular font. Additional information on PAC values and TEEL values and links to other sources of information is provided on the Subcommittee for Consequence Assessment and Protective Action (SCAPA) webpage at: http://orise.orau.gov/emi/scapa/teels.htm. 1 Information on the Chemical Abstract Service and CASRNs is provided at http://info.cas.org/.
