Publication of Revision 29A of the PAC database

Published in Resources on 7/29/2018

Revision 29A of the Protective Action Criteria (PAC) database, located at http://sp.eota.energy.gov/pac has been published. EMI SIG recognizes that PACs are essential components for planning and response to uncontrolled releases of hazardous chemicals. These criteria, combined with estimates of exposure, provide the information necessary to evaluate chemical release events for the purpose of taking appropriate protective actions.

A mathematical error in the calculation of a TEEL-2 value for potassium dichromate (CAS# 7778-50-9) has been corrected. Per our procedures, correcting the error causes Revision 29 to be republished as Revision 29A when the error is corrected.  The TEEL-2 value for potassium dichromate is the only change in the database.  All files on the PAC site have now been updated.

 

As you may recall, with the publication of Revision 29 in May 2016, we reached a culminating point in the project.  (EPA’s AEGL project is also at a culminating point.)  There are no current plans for development of a full Revision of the TEEL/PAC database or an in-depth review of the existing TEELs.

A little more background…

 

This site provides information on 3,146 chemicals and allows users to access the U.S. Department of Energy's (DOE's) current data set of PAC values in a variety of ways: as a searchable database, as an Excel file, and as a series of tables in PDF format. It also provides archived versions of the PACs for reference.

 

Emergency exposure limits are essential components of planning for the uncontrolled release of hazardous chemicals. These limits, combined with estimates of exposure, provide the information necessary to identify and evaluate accidents for the purpose of taking appropriate protective actions. During an emergency response to an uncontrolled release, these limits may be used to evaluate the severity of the event, to identify potential outcomes, and to decide what protective actions should be taken. In anticipation of an uncontrolled release, these limits may also be used to estimate the consequences of an uncontrolled release and to plan emergency responses.​
