OSHA's Hazard Communication Standard (HCS) is being modified

March 28 2012

TAUC members should be aware of the fact that OSHA is modifying its Hazard Communication Standard (HCS) to conform to the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS).

The 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, and requirements for employee training on labels and safety data sheets.

OSHA is also modifying provisions 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.

DATES: This final rule becomes effective on May 25, 2012. Other dates as indicated in the table below:
