Accessing the World-Wide Web for Data Bases

The reader can find an almost endless supply of chemical and physical properties for hundreds of thousands of chemicals and tradename products on the Web. The easiest access to general information resources that contain health risk and some air transport properties are those sites which contain Material Safety Data Sheets (MSDSs). The following are a list of but a few sites worth exploring for chemical-specific information  

Visit http //cortex.uchc.edu/ safety/ehs/msds-l.html. This site is accessible by UCHC network registered users only. Once registered, you can access 70,000 MSDSs from Sigma, Aldrich, and Fluka on-line. The MSDSs are available in several languages (English, French, German, Spanish and Italian languages). Updates are done on a quarterly basis. 

Visithttp //ntp-support.niehs.nih.gov/Main Pages/Chem-HS.html. This is the site for the National Institute of Environmental Health Science. You will find MSDS-type chemical health and safety information from the National Toxicology Program. Chemical searches can be performed by chemical name, synonym, or CAS (Chemical Abstract Service) number. 

Visit gopher //atlas.chem.Utah.edu/ll/MSDS. This site is run by the University of Utah. To search, you choose the alphabetical folder that contains the chemical of interest. You will be presented with a list of chemicals to select from. 

Visit gopher //quasar.tach.net 3020/71/msds. This is the Vermont state SIRI Web. You will find a searchable (manufacturer or product name) gopher index of MSDSs.
