Online NIOSH Pocket Guide to Chemical Hazards
- not MSDS, but an extensive guide to chemical hazards
- The NPG is a source of general industrial hygiene information on several hundred chemicals/classes for workers, employers, and occupational health professionals. It presents key information and data in abbreviated or tabular form for chemicals or substance groupings (e.g. cyanides, fluorides, manganese compounds) that are found in the work environment.
You can download a free stand-alone HTML version of the NPG compressed as a
ZIP file. The ZIP file contains a condensed version of the NPG. All
non-Pocket Guide links were removed so that this set of files acts as a
"stand-alone" database. These files can be used with a standard web browser
or on some mobile devices.
