Understanding the GHS Labeling System
![Page 3: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System .

Background The federal Occupational Safety & Health
Administration (OSHA) has made changes to the 1983 Federal Hazard Communication
Standard based on the United Nations International Global Harmonization System of
Classification and Labeling of Chemicals (GHS), Revision 3. This went into effect in
May 2012.
![Page 4: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/4.jpg)
Why change? When OSHA originally created the HazCom Standard, it was “performance based,” which
meant that while the Standard described what companies needed to accomplish, it left them free to decide exactly how they would do
that.
![Page 5: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/5.jpg)
What is the Global Harmonization System?
It is an international system used to classify hazardous chemicals
and standardize hazard information on product labels and
safety data sheets.
![Page 6: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/6.jpg)
Who do these changes affect?
• Chemical manufacturers • Chemical importers/transporters • Chemical distributors • Employers • Workers who use chemicals
![Page 7: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/7.jpg)
HazCom 2012 It doesn’t replace OSHA’s HazCom Standard, it “enhances” the Standard. It does not change a workers’ right to know if they are being exposed to hazardous chemicals. It includes information on: • What to do to protect themselves from the
hazards of the chemical product • Where to go to get more information
![Page 8: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/8.jpg)
What HazCom 2012 Does Change
1. Hazard Classification: Provides specific criteria for classification of health and physical hazards, as well as classification of chemical mixtures.
2. GHS first divides chemicals into “Hazard Classes” then into “Hazard Categories”
![Page 9: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/9.jpg)
What HazCom 2012 Does Change
2. Labels: Chemical manufacturers and importers will be required to provide a standardized label that includes: – Product identifier – Signal words – A hazard statement – A precautionary statement – Pictograms – Supplemental information
![Page 10: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/10.jpg)
What HazCom 2012 Does Change
3. Safety Data Sheets will replace Material Safety Data Sheets and have a new
16-section format
![Page 11: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/11.jpg)
4. Right-to-Know laws are evolving into “Right to Understand” regulations, meaning workers who handle hazardous chemicals must be trained in a format they can understand to become familiar with the content of the safety data sheets and labeling requirements.
What HazCom 2012 Does Change
![Page 12: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/12.jpg)
HazCom Training All states must adopt these changes.
Washington State’s Department of Labor and Industry (L&I) Division of Occupational
Safety and Health (DOSH) states that employees who may be exposed to hazardous chemicals must be trained on the safety data sheet format and new labelling elements by
June 1, 2014.
![Page 13: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/13.jpg)
HazCom Training
Training must be presented in a manner workers can understand, even for • Non-English speaking workers • Illiterate workers The ultimate goal is to more effectively prevent injuries and illnesses and save lives.
![Page 14: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/14.jpg)
HazCom 2012
Once GHS-based requirements go into effect in Washington State, required HazCom programs will
need to be modified to include the new labels and standardized SDS
format.
![Page 15: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System . Background](https://reader033.fdocuments.net/reader033/viewer/2022060219/5f06bc877e708231d4197a31/html5/thumbnails/15.jpg)
Deadlines for Compliance • All hazardous chemicals shipped after June 1,
2015 must be labeled with the six new specific elements of the 2012 Hazard Communication Standard, but are permitted to comply with regulation earlier.
• Distributors may ship containers labeled by manufacturers or importers with earlier HazCom compliance until December 1, 2015.

Labels
Labels, as defined in the HCS, are an appropriate group of written, printed, or
graphic informational elements concerning a hazardous chemical that are affixed to, printed on, or attached to the immediate container of a
hazardous chemical, or to the outside packaging.
![Page 18: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System .

Label Requirements
1. PRODUCT IDENTIFIER This can be (but not limited to) the chemical name, code number or batch number. The identifier must be both on the label and in section 1 of the SDS.
![Page 19: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System .

Label Requirements
2. SIGNAL WORDS There are only two: “Danger” and “Warning” and only one is used on a label.
“Warning” is used for less severe hazards than “Danger.” If both apply, “Danger” should appear on the label.
![Page 20: International Global Harmonization System (GHS) of ...€¦ · Harmonization System (GHS) of Classification and Labeling of Chemicals . Understanding the GHS Labeling System .
