A Material Safety Data Sheet (MSDS) provides information about the associated hazards of a chemical. The lab must maintain an MSDS, either a physical hard copy or electronically, for all chemicals used. You have a right to know about the hazards associated of the chemicals in your lab. Refer to these links below regarding MSDS’. If you cannot locate an MSDS for a chemical in your lab speak with your PI or contact the EH&S Manager.
