I recently became aware that the National Institute for Occupational Safety and Health (NIOSH) has made its popular
Pocket Guide to Chemical Hazards available for download with the ability to create a disc with CD-ROM software. The Pocket Guide is intended as a source of general industrial hygiene information for workers, employers, and occupational health professionals, to assist them in recognizing and controlling occupational chemical hazards.
The 677 chemicals or substance groupings that are contained in the guide include all substances for which NIOSH has Recommended Exposure Limits (RELs) as well as those with Permissible Exposure Limits (PELs) as defined in the OSHA General Industry Air Contaminants Standard (29 CFR 1910.1000). Information covered in the guide includes chemical name and structure, Chemical Abstracts Service (CAS) registry number, Registry of Toxic Effects of Chemical Substances (RTECS) number, U.S. Department of Transportation (DOT) identification and guide numbers, and synonyms and trade names for each chemical compound. All of this information is listed in an abbreviated tabular form, making the guide very user friendly.
You can access the guide at
http://www.cdc.gov/niosh/npg, or download the NIOSH Guide to Chemical Hazards zip file, which contains a condensed version of the pocket guide at
http://www.cdc.gov/niosh/docs/2010-168c/. This is a great, free tool for every worker to have.
