Table 2: Protective Action Criteria (PAC) Rev 23 based on applicable AEGLs, ERPGs, or TEELs (chemicals listed in alphabetical order) PAC Rev 23 – August 2007 Table 2 presents an alphabetical listing of the chemicals in the PAC data set and provides Chemical Abstracts Service Registry Numbers (CAS RNs)1, PAC data, and technical comments focusing on changes in the PACs since the previous version of the PAC/TEEL data set (Rev 21). PACs are provided for TEEL-0 (i.e., PAC-0), PAC-1, PAC-2, and PAC-3. Values are usually given in parts per million (ppm) for gases and volatile liquids and in milligrams per cubic meter (mg/m3) for particulate materials (aerosols) and nonvolatile liquids. The columns presented in Table 2 provide the following information: Heading Definition No. The ordered numbering of the chemicals as they appear in this alphabetical listing. Chemical The common name of the chemical compound. Compound CAS RN The Chemical Abstracts Service Registry Number for this chemical. TEEL-0 This is the threshold concentration below which most people will experience no appreciable risk of 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-3 value. PAC-3 Based on the applicable AEGL-3, ERPG-3, or TEEL-3 value. Units The units for the PAC values (ppm or mg/m3). Comments Technical comments by the developers of the PAC data set. Indicates changes from the previous version of the PAC/TEEL data set. A “T” in the comment field, typically stands for “TEEL.” The term “SAR,” often in red font, stands for “Structure Activity Relationships.” This column will be enhanced in the near future to improve the clarity and completeness of its information. • Chemicals for which AEGLs are available have their chemical name and CAS RN displayed in a bolded and larger font. • Chemicals for which ERPGs are available, but no AEGLs, have their chemical name and CAS RN displayed in a bolded font. • Chemicals for which TEELs are available, but no AEGLs or ERPGs, have their chemical name and CAS RN displayed using a regular font. In the PAC columns of Table 2: • Bold, green, and italicized font indicates a PAC between 10% and up to 50% of the LEL (10% LEL ≤ PAC < 50% LEL). 1 Visit http://info.cas.org/ for information on the Chemical Abstracts Service and CAS RNs. Introduction to PAC Table 2 – PAC Rev 23 – 08/30/2007 Page 1 of 3 • Bold, underlined, pink and italicized font indicates a PAC between 50% and up to 100% of the LEL (50% LEL ≤ PAC < 100% LEL). • Bold, double underlined, red and italicized font indicates a PAC at 100% or more of the LEL (PAC ≥ 100% LEL). Additional information on the chemicals presented in Table 2 is provided in PAC Tables 1, 3, and 4. Definitions of AEGLs, ERPGs, and TEELs AEGLs AEGL-1 The airborne concentration (expressed as parts per million or milligrams per cubic meter (ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, could experience notable discomfort, irritation, or certain asymptomatic nonsensory effects. However, the effects are not disabling and are transient and reversible upon cessation of exposure. AEGL-2 The airborne concentration (expressed as ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, could experience irreversible or other serious, long-lasting adverse health effects or an impaired ability to escape. AEGL-3 The airborne concentration (expressed as ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, could experience life-threatening health effects or death. ERPGs ERPG-1 The maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to 1 hr without experiencing other than mild transient adverse health effects or perceiving a clearly defined, objectionable odor. ERPG-2 The maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to 1 hr without experiencing or developing irreversible or other serious health effects or symptoms which could impair an individual's ability to take protective action. ERPG-3 The maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to 1 hour without experiencing or developing life-threatening health effects. TEELs TEEL-0 The threshold concentration below which most people will experience no appreciable risk of health effects. TEEL-1 The maximum concentration in air below which it is believed nearly all individuals could be exposed without experiencing other than mild transient adverse health effects or perceiving a clearly defined objectionable odor. TEEL-2 The maximum concentration in air below which it is believed nearly all individuals could be exposed without experiencing or developing irreversible or other serious health effects or symptoms that could impair their abilities to take protective action. TEEL-3 The maximum concentration in air below which it is believed nearly all individuals could be exposed without experiencing or developing life-threatening health effects. Introduction to PAC Table 2 – PAC Rev 23 – 08/30/2007 Page 2 of 3 Table 2, other PAC Tables, introductory/explanatory material (including a glossary of acronyms and abbreviations), definitions of PAC values, and alternative methods of displaying PAC information are available electronically at: http://www.hss.energy.gov/HealthSafety/WSHP/chem_safety/teel.html. Table 4 might be of particular interest because it presents information on the source of the PACs. Additional technical information on PACs and TEELs, contact information, and links to other sources of information is accessible on the Subcommittee for Consequence Assessment and Protective Action (SCAPA) webpages at: http://orise.orau.gov/emi/scapa/teels.htm. Chemicals without an identified CAS RN number are issued an identification number, preceded by the letter “z,” for purposes of the PAC data set. The same “z” number that was used in “TEELs Rev 21” has been retained, where applicable.
