There were many individuals involved, from a multitude of countries, internationalorganizations, and stakeholder organizations. Their work spanned a wide range of expertise, from toxicology to fire protection, and ultimately required extensive goodwill and the willingness to compromise, in order to achieve thissystem.2.The work began with the premise that existing systems should be harmonized in order to develop a single,globally harmonized system to address classification of chemicals, labels, and safety data sheets. This was not a totallynovel concept since harmonization of classification and labelling was already largely in place for physical hazards andacute toxicity in the transport sector, based on the work of the United Nations Economic and Social Council'sCommittee of Experts on the Transport of Dangerous Goods . Harmonization had not been achieved in the workplace orconsumer sectors, however, and transport requirements in countries were often not harmonized with those of othersectors.3.The international mandate that provided the impetus for completing this work was adopted at the 1992 UnitedNations Conference on Environment and Development (UNCED), as reflected in Agenda 21, para.19.27:"A globally harmonized hazard classification and compatible labelling system, including material safety data sheetsand easily understandable symbols, should be available, if feasible, by the year 2000".4.The work was coordinated and managed under the auspices of the Interorganization Programme for the SoundManagement of Chemicals (IOMC) Coordinating Group for the Harmonization of Chemical Classification Systems(CG/HCCS). The technical focal points for completing the work were the International Labour Organization (ILO); theOrganisation f...
