The United States and many other countries throughout the world have developed a Globally Harmonized System for the Classification and Labeling of Chemicals (GHS). The GHS is the culmination of more than a decade of work. After ten years of technical work and negotiation, a United Nations Economic and Social Council Subcommittee adopted the Globally Harmonized System for Classification and Labeling ("GHS") and recommended that it be disseminated throughout the world.  By promoting common, consistent criteria for classifying chemicals and developing compatible labeling and safety data sheets, the Globally Harmonized System is intended to enhance public health and environmental protection, as well as reduce barriers to trade.

The implementation of the GHS can have numerous benefits for governments, business and industry, and public interest and labour groups. Implementing the GHS also provides a number of international benefits.  It is anticipated that application of the GHS will:

·         Enhance the protection of human health and the environment by providing an internationally comprehensible system,

·         Provide a recognized framework to develop regulations for those countries without existing systems,

·         Facilitate international trade in chemicals whose hazards have been identified on an international basis,

·         Reduce the need for testing and evaluation against multiple classification systems.

·         The GHS can also support the implementations of the Millennium Development Goals to “ensure environmental sustainability”.

The tangible benefits to governments are:

·         Fewer chemical accidents and incidents,

·         Lower health care costs,

·         Improved protection of workers and the public from chemical hazards,

·         Avoiding duplication of effort in creating national systems,

·         Reduction in the costs of enforcement,

·         Improved reputation on chemical issues, both domestically and internationally.

Benefits to business and industry include:

·         A safer work environment and improved relations with employees,

·         An increase in efficiency and reduced costs from compliance with hazard communication regulations,

·         Application of expert systems resulting in maximizing expert resources and minimizing labor and costs,

·         Expanded use of training programs on health and safety,

·         Reduced costs due to fewer accidents and illnesses,

·         Improved corporate image and credibility.

Benefits to workers and the public include:

·         Improved safety for workers and others through consistent and simplified communications on chemical hazards and practices to follow for safe handling and use,

·         Greater awareness of hazards, resulting in safer use of chemicals in the workplace and in the home.

The purpose of the GHS is to promote common, consistent criteria for classifying chemicals according to their health, physical and environmental hazards, and to encourage the use of compatible hazard labels, material safety data sheets for workers, and other hazard communication information based on the resulting classifications.

Now, OSHA is in the process of adopting these requirements for American workplaces.   The standardization will ultimately be good news for all concerned, facilitating improvements to both efficiency and worker safety. However, in the short term, the implementation of the GHS will require changes in all American workplace hazcom and other safety programs-including new labels and MSDS’s.
