Table 4: Protective Action Criteria (PAC) Rev 26 based on applicable 60-minute AEGLs, ERPGs, or TEELs. The chemicals are listed in alphabetical order and the values are presented in mg/m3. September 2010 Table 4 is an alphabetical list of the chemical substances and their corresponding PAC values in mass per unit volume (mg/m3). The conversion of ppm to mg/m3 was carried out assuming normal temperature and pressure, 25°C and 760 mm Hg. The final column in this table provides “Source of PACs” information. 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 name of the chemical substance submitted to the PAC development team CASRN The Chemical Abstract Service Registry Number1 for this chemical TEEL-0 This is the threshold concentration below which most people will experience no adverse health effects. This value is always referred to as a TEEL-0 because AEGL-0 and 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 are provided by the PAC development team, TEEL-0, PAC-1, indicating the source of the data used to derive PAC values. On-going PAC-2, PAC-3 efforts include 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/.
