Safety Data Sheets Under the New Globally Harmonized System

Quick Tips #250

New chemicals are developed every day and for use in an ever-widening variety of applications. Providing accurate, clear and concise information to people who use, handle or store hazardous industrial chemicals is paramount.

On March 26, 2012, the Department of Labor adopted the United Nations' Globally Harmonized System of Classification and Labeling of Chemicals—otherwise known as GHS. This change ensures that OSHA's current Hazard Communication Standard (HCS) is aligned with internationally-developed guidelines for the categorization and labeling of hazardous substances.

Under the new GHS ruling, material safety data sheets (MSDS), will be referred to and called SDS (or Safety Data Sheets). The new standards affect any workplace that manufactures, uses, transports, or stores hazardous chemicals. One specific change in this ruling is to the ANSI Standardized MSDS format. The original 16-section MSDS format created by ANSI Z400.1 (2010 Rev.) will be replaced by the new SDS under the GHS system for classification for hazardous chemicals.

SDS's are the backbone of the Hazardous Communication System (HCS). They provide comprehensive and specific chemical information used not only by workplaces that manufacture, use, transport or store hazardous chemicals, but also by emergency responders, poison control centers and transporters of dangerous goods.

The standardized 16-section SDS mirrors the American National Standard for Hazardous Workplace Chemical's - Hazard Evaluation and Safety Data Sheet and Precautionary Labeling Preparation, ANSI Z400.1/Z129-1-2010. To be compliant, the SDS must have all 16 sections. OSHA however will not be enforcing sections 12-15 as they fall outside of their jurisdiction.

Companies will have nearly two years to train their employees on the new GHS system. U.S. employees will need to be up to date in both the old and new regulations before December 2013, this will allow for a smoother transition to the new GHS SDS format. OSHA's final rule imposes the following deadlines on U.S. companies involved with chemicals:

  • May 25, 2012: Transition period commences.
  • December 1, 2013: Deadline to train employees on new labels.
  • June 1, 2015: Deadline to comply with all amended provisions.
  • June 1, 2016: Deadline to update alternative workplace labeling and hazard communication programs, and provide any additional employee training.

Other significant changes under the new rule include:

  • Labels and SDSs will follow a more standardized format and contain a greater number of prescribed elements based on the chemical's classification.
  • Formulators of mixtures will no longer be able to prepare an SDS by attaching component SDSs to a cover sheet; they must now provide a new SDS for the mixture itself.
Commonly Asked Questions
Q.   When do SDSs need to be updated?
 
A.   The information required on the safety data sheet (SDS) will remain essentially the same as that in the current standard. The current Hazard Communication Standard (HCS) indicates what information has to be included on an SDS but does not specify a format for presentation or order of information. The revised HCS requires that the information on the SDS is presented using consistent headings in a specified sequence.
 
Q.   How is the Safety Data Sheet (SDS) changing under the revised Hazard Communication Standard?
 
A.   For pipes of less than 3/4" in diameter the use of a permanently legible tag is recommended.
Q.   Where can I get more information on the GHS and the impact on the HCS?
 
A.   You can find information on the GHS and any impact it may have related to OSHA on the OSHA website: http://www.osha.gov/as/opa/facts-hcs-ghs.html
