About the DCHAS-L Archives

This section of the ILPI web site is a repository for archived emails from the American Chemical Society's Division of Chemical Health & Safety email discussion list, DCHAS-L.

Over the years, the DCHAS-L list and archives have been hosted at several universities. In 2003, the list moved from Southern Illinois University to the University of Vermont and in late 2011 it moved to Cornell University. In all cases, the archives were tied to the host university's systems and software architectures which meant that when the list moved from one school to another the archive access was lost. Currently, Cornell limits archive retrieval to the Cornell community, so public access to the Archives from their list server is not available.

In January of 2012, DCHAS member Rob Toreki took on the task of converting the accumulated raw archive files into a form that is software and site-independent. The essentially unreadable bulk archive files were broken into over 6,100 individual HTML files each of which contains a single posting. He then added navigational controls, installed master indices by year, made the archive keyword searchable, and created a mechanism by which new posts to the list appear in the archive in near-real time. Maintenance and hosting of this archive is generously provided by Rob's company, Safety Emporium, a division of ILPI.

This archive includes all DCHAS-L posts from January 14, 2003 to present. The reader should approach old posts with caution - while some contain timeless nuggets of information from exceedingly wise individuals who are no longer with us, specific regulatory information/opinions may be outdated.

For those currently subscribed to DCHAS-L, the following email commands are available:
