The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is a worldwide program set forth at the United Nations Conference on the Environment and Development (UNCED) in 1992. The goal is to provide a consistent, globally harmonized system to address classification of chemical hazards on labels and safety data sheets. The GHS aims to ensure that chemical information on physical hazards and toxicity are in a consistent form for protecting human health and the environment.
