In 2012, OSHA revised the HCS to be consistent with the United Nation’s Globally Harmonized System (GHS) of classification and labeling of chemicals.
The GHS is an international approach to hazard communication that provides specific criteria for classification of chemical hazards and a standardized approach to label elements and safety data sheets. Since the US is both a major importer and exporter of chemicals, American workers often see labels and safety data sheets required by other countries.
As countries around the world adopt the GHS, chemicals crossing borders will have consistent information. This will enhance both employer and worker comprehension of the hazards, and will help to ensure appropriate handling and safe use of workplace chemicals.
These are the dates for the new requirements:
June 1, 2016 - Employers must update alternative workplace labeling and hazard communication program as necessary, and provide additional employee training for newly identified physical or health hazards.
