A Material Safety Data Sheet (MSDS) is a legal document containing information on the potential effects on your health from exposure to chemicals. It is a nine-section document, dealing with toxicity, use, storage, handling and emergency procedures related to any products the government feels need to be controlled It describes the possible hazards involved with the product, how to use it safely
