MSDS Material Safety Data Sheets Technical documents provided by chemical manufacturers Describe specific properties of chemicals Mandated by OSHA A copy is to be kept on file for each hazardous chemical used in a laboratory Know where MSDS are located and how to use them
Using MSDS Determine PPE requirements for the chemical you are using Learn what specific hazards are associated with the chemical’s use Know how to handle any spills or accidental release of chemicals Determine how to dispose of waste produced associated with using the chemical
Chemical Labels All containers of potentially hazardous chemicals must be labeled sufficiently to allow identification by outsiders or new lab personnel Know how to read chemical labels and where to find information Remember many chemicals look the same!
Chemical Labeling in the Lab Any chemicals removed from the original containers must be labeled with name and hazard information
