Protective Action Criteria for 365bet娱乐 (PACs)

The PACs dataset is a hierarchy-based system of the three common public exposure guideline systems: AEGLs, ERPGs, and TEELs. A particular hazardous substance may have values in any鈥攐r all鈥攐f these systems.

The PACs dataset implements the following hierarchy when choosing which values to use for the PACs:

  1. Final, 60-minute AEGL values (preferred)
  2. Interim, 60-minute AEGL values
  3. ERPG values
  4. TEEL values

The PACs dataset has a single set of values (PAC-1, PAC-2, and PAC-3) for each chemical, but the source of those values will vary. So, for instance, the PAC-3 value for one chemical might be an ERPG-3 and the PAC-3 value for a different chemical might be the TEEL-3. A hierarchical system can be helpful for choosing Levels of Concern for chemicals that are defined under two or more of the public exposure guidelines. See the AEGLs, ERPGs, and TEELs topics for more information on each of those datasets.

The PACs dataset is created by the TEEL developers (Department of Energy, Subcommittee on Consequence Assessment and Protective Actions).
