Did you know that in each of the last 10 years the hazard communication standard has been on the top 10 most cited regulations by the Occupational Safety and Health Administration (OSHA)? In 2012, OSHA implemented changes to the hazard communication standard to help align the U.S. with the international community’s Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This rule became effective on May 25, 2012. This means more changes to a rule that has given a lot of companies problems in the past.

U.S. Secretary of Labor Hilda Solis said, “Exposure to hazardous chemicals is one of the most serious threats facing American workers today. Revising OSHA’s Hazard Communication Standard will improve the quality and consistency of hazard information, making it safer for workers to do their jobs and easier for employers to stay competitive.”

The goal of the update to the Hazard Communication Standard (HCS) is to provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. Once implemented, the revised standard will improve the quality and consistency of hazard information in the workplace, making it safer for workers by providing information that is easy to understand on appropriate handling and safe use of hazardous chemicals.

Here are some of the major changes to the existing rule:

  • Hazard Classification: The new rule will provide specific criteria for classification of health and physical hazards, as well as classification of mixtures.
  • Labels: Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram, and hazard statement for each hazard class and category. Precautionary statements shall also be provided.
  • Safety Data Sheets: (Formerly Material Safety Data Sheets or MSDS) These will now have a specified 16-section format.
  • Information and Training: Employers are required to train workers by December 1, 2013, on the new label elements and safety data sheet format to facilitate recognition and understanding.
