Material Safety Data Sheets (MSDS) are an invaluable information source for those working with dangerous substances such as chemicals. One problem often encountered, though, is having access to the sheet when needed; that's where the aptly named Web site, Where to Find Material Safety Data Sheets On the Internet, comes in. The site is provided by Interactive Learning Paradigms Incorporated and compiles around 100 links to free MSDS. The pages are categorized into general sites, government and nonprofit agencies, chemical manufacturers and suppliers, pesticides, and miscellaneous sites -- each with a brief description. The only downfall of the site is the lack of a MSDS search engine, which apparently is going to change in the future according to the Webmaster. Other items of interest include regulations, suppliers, software, a quiz, MSDS facts, books, and more.
