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

Chemical Storage

• Refer to chemical label and MSDS for storage requirements

• Do not store chemicals in inappropriate containers

• Make sure containers are adequately labeled with contents

• Do not store chemicals under inappropriate conditions or incorrect locations

Chemical Storage

Working With Chemicals

• Be aware of chemical reactivity and hazards when selecting vessels for mixing or transport

• Check MSDS or chemical label for safe working conditions for that chemical (under hood, etc.)

• Use hazardous chemicals in quantities small enough to be easily handled

• Never directly inhale or ingest any laboratory chemical
