Availability and ready access to Safety Data Sheets (SDSs) is a requirement under OSHA Hazard Communication and lab safety standards. Safety Data Sheet contains detailed information including risk and hazards associated with a specific chemical and is unique to each manufacturer. While electronic access is acceptable, chemical users are required to maintain hard copies of the appropriate SDS for high hazard and frequently/large volume used chemicals. Researchers must review contents of the SDS before placing a new order, using chemicals in a new experiment, or modifying an existing experiment.
