The Occupational Safety and Health Administration has proposed a rule that would align its hazard communication standard with provisions of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

"The proposal to align the hazard communication standard with the GHS will improve the consistency and effectiveness of hazard communications and reduce chemical-related injuries, illnesses, and fatalities," said acting Assistant Secretary of Labor for OSHA Jordan Barab.

The proposed rule was published in the September 30, 2009, edition of the Federal Register. The proposed modifications to the standard include:

• Revised criteria for classification of chemical hazards;
• Revised labeling provisions that include requirements for use of standardized signal words, pictograms, hazard statements, and precautionary statements;
• A specified format for safety data sheets; and
• Related revisions to definitions of terms used in the standard, requirements for employee training on labels and safety data sheets.

In addiiton, OSHA is proposing changes to provisions of a number of other standards, including standards for flammable and combustible liquids, process safety management, and most substance-specific health standards, to ensure consistency with the modified HCS requirements.
