GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals. It is an internationally agreed-upon standard developed by the United Nations to harmonize the classification and communication of chemical hazards worldwide
. The system provides:
- Standardized criteria for classifying chemical hazards (health, physical, and environmental)
- Uniform label elements including hazard pictograms, signal words, and precautionary statements
- A consistent format for Safety Data Sheets (SDS) with 16 sections detailing chemical safety information
The goal of GHS is to improve protection of human health and the environment by providing clear, consistent hazard communication globally, facilitating international trade, and reducing regulatory burdens caused by multiple classification systems
. Many countries and regulatory agencies, including OSHA in the United States and the European Union through its CLP Regulation, have adopted GHS standards to ensure safer handling, transport, and use of hazardous chemicals
