The Globally Harmonized System includes provisions for both classification criteria and hazard
communication elements, i.e., labels and safety data sheets.
The following "GHS Standardized Hazard Symbols" picture is the standard
symbols which should be used in the GHS.
With the exception of the new symbol which will be used for certain health hazard, the
exclamation mark and the fish and tree, they are part of the standard symbol set used in the UN
Recommendations on the Transport of Dangerous Goods.
