GHS classification

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was developed by the United Nations for providing consistent guidelines that all countries can use in classifying and labeling hazardous materials. Individual countries may have differing definitions of what constitutes a hazardous material, at what temperature a substance is considered flammable, and so forth; likewise, they may use different labeling systems. The GHS resolves these inconsistencies by providing guidelines that can be used by all countries.
