Globally Harmonized System (GHS)

[ EH & S Home ]

WISHA has revised its Hazard Communication Standard to align it with the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This revision of the Hazard Communication Standard includes two significant changes: (1) new labeling elements and (2) a standardized format for Safety Data Sheets (SDSs), formally known as Material Safety Data Sheets.




1. Product IdentifierIdentifies the substance by name or number
2. PictogramsConvey specific information about the hazard of a substance
3. Signal WordAlerts users on the severity of hazard "Danger" or "Warning"
4. Hazard StatementsDescribe the nature of the hazards of a substance
5. Precautionary StatementsDescribe recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to the substance or improper
storage / handling
6. Supplier InformationName, address, and telephone number of the manufacturer, distributor, or importer

Safety Data Sheets (SDS)

Manufacturer, distributors, and importers are required to provide Safety Data Sheets (SDSs), formerly known as Material Safety Data Sheets (MSDSs), to communicate the hazards of hazardous substances. The WISHA revision of the Hazard Communication Standard requires SDSs to follow a standardized 16-section format.

1. Identification9. Physical and Chemical Properties
2. Hazard(s) Identification10. Stability and Reactivity
3. Composition/Information on Ingredients11. Toxicological Information
4. First-aid Measures12. Ecological Information
5. Fire-fighting Measures13. Disposal Considerations
6. Accidental Release Measures14. Transport Information
