Material Safety Data Sheets (MSDS) are legally required documents that list chemicals in products and what you should do to protect yourself from them. Back in the day they were hard to find, kind of like in The Hitchhiker's Guide to the Galaxy, where to find bypass plans, Arthur Dent has to look in the cellar with no lights, no stairs, "in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign outside the door saying "beware of the leopard!"

Now, thanks to the power of the internet, they are much easier to find. Over at Parentables, Chemist Christine Lepisto does a terrific post explaining what they are and how to use them: a must-read at How to Find "Secret" Information on Chemical Hazards: Read the Safety Data Sheet
