Chem PACs/TEELs

Protective Action Criteria for Chemicals - Including AEGLs, ERPGs, & TEELs

Protective Action Criteria (PAC) for emergency planning of chemical release events are based on the following chemical exposure limit values:

  • Acute Exposure Guideline Level (AEGL) values published by the U.S. Environmental Protection Agency (EPA)
  • Emergency Response Planning Guideline (ERPG) values produced by the American Industrial Hygiene Association (AIHA)
  • Temporary Emergency Exposure Limit (TEEL) values developed by SCAPA.

The PAC data set contains exposure limit values for more than 3,200 chemicals. Originally called the “TEEL data set,” the name has been changed to the “PAC data set” to emphasize its inclusion of AEGLs and ERPGs as well as TEELs.

The PAC data set (including AEGLs, ERPGs, and TEELs) is accessible as a searchable database, Excel workbook, and formatted tables:

AEGLs, ERPGs, TEELs, and other useful information for chemicals of concern are provided in two different formats – data tables (in .pdf format) and an Excel workbook.

The current version of the PAC data set is: Revision 25 (August, 2009).
