The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an internationally agreed-upon system, created by the United Nations beginning in 1992 and as of 2015 is not yet fully implemented in many countries. It was designed to replace the various classification and labeling standards used in different countries by using consistent criteria on a global level. It supersedes the relevant European Union system, which has implemented the United Nations' GHS into EU law as the CLP Regulation and United States Occupational Safety and Health Administration standards. ==History== The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was developed beginning at the United Nations Rio Conference in 1992, when the International Labour Organization (ILO), the Organisation for Economic Co-operation and Development (OECD), various governments and other stakeholders met at a United Nations conference. Before it was created and implemented, there were many different regulations on hazard classification in use in different countries. While those systems may have been similar in content and approach, they resulted in multiple standards, classifications and labels for the same hazard. Given the extent of international trade in chemicals and the potential impact on neighboring countries when controls are not implemented, countries determined that a worldwide approach was necessary. The GHS was designed as one universal standard for all countries to follow and to replace all the diverse classification systems however, it is not compulsory under UN law. The system provides the infrastructure for participating countries to implement a hazard classification and hazard communication standard, which many less economically developed countries would not have had the money to create themselves. In the longer term, the GHS is expected to improve knowledge of the chronic health hazards of chemicals and encourage a move towards the elimination of hazardous chemicals, especially carcinogens, mutagens and reproductive toxicants, or their replacement with less hazardous ones. The final "Globally Harmonized System (GHS) for classification and labeling" standard was created at the 1992 Rio Conference on Environment and Development with the statement that "A globally harmonized hazard classification and compatible labeling system, including material safety data sheets and easily understandable symbols, should be available if feasible, by the year 2000". An illustration shows the timeline of GHS and the progress needed to completely put GHS into place. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Globally Harmonized System of Classification and Labelling of Chemicals」の詳細全文を読む スポンサード リンク
