Global Harmonized System (GHS)

Why the need?

The UN came together, realizing that there was a global need for harmonizing the communication of hazardous chemicals.  Each country had some sort of system, however with each looking and saying very different information, it was not easy to understand.  The matters are complicated with many chemical manufacturers shipping product into multiple countries, and the local country possibly not even understanding the information on the label that comes in the door.

Country-by-country, around the globe, hazard classification and communication laws are similar in purpose, but different enough to result in inconsistent hazard classification for similar products, and dissimilar looking labels and SDS.

Need to harmonize and improve safety information and facilitate international trade through compatible classification methods, SDS and labels.

United Nations Conference on Environment and Development (1992) mandated a globally harmonized chemical classification and labeling system

Member States actively involved in creation:

  • Unites States (OSHA representatives)
  • Canada
  • European Union
  • Additional UN Members

GHS was formally adopted in 2002

  • United Nations Committee of Experts on the Transport of Dangerous Goods
  • iGlobally Harmonized System of Classification and Labeling of Chemicals

Goal of GHS

  • Written by the UN, the goal of the GHS is to harmonize differing workplace hazard classification and labeling systems across the world

How GHS accomplishes that goal

  • Harmonizes how hazardous substances and mixtures are classified
  • Changes how hazard information is communicated (new pictograms and phrases)
  • Streamlines the format of SDS and labels

What is GHS

This showcases the different styles and types of hazardous chemical formats in various countries/regions.  All of these styles (Figure 1 -3 shown below) will now move to the GHS format ( figure 4 shown below) GHS Status in America.

GHS Status in America 

As discussed, in the US it’s in final stages of development.

In Canada, Health Canada is the responsible agency for overseeing adoption of GHS.  Health Canada is currently reviewing GHS for incorporation into WHMIS.  It’s further hoped and anticipated that the finalized regulation will be very comparable to the US regulation.  That is also of course a primary objective of what the UN and all participating countries are bent on accomplishing.

Mexico has actually come forward with a voluntary standard that addresses GHS, NMXR019SCFI-2011.  However its pre-existing communication regulation, NOM018STPS-2000 still remains in force.  This results in dual labeling and SDS’s Companies exporting and importing from nations that have implemented GHS are expected to comply with both.  I understand that the ANIQ national association has requested authorization from the Labor Secretary to develop an alternate procedure that can comply with both.

Finally, Brazil has implemented GHS for substances, following the course that the EU has taken, and has set a date of 1st of June 2015, for mixtures.

United States – adopted by OSHA as of May 2012 

Canada Reviewing for development:

  • Health Canada Policy and Programme Services Office is national coordinator.
  • Currently reviewing GHS for incorporation into WHMIS
  • Estimated changes to WHMIS occurring in Spring 2013

Mexico – Voluntary standard proclaimed:

  • The first NAFTA member to adopt the GHS as a basis for national health & safety regulations
  • Proclaimed a new voluntary standard, NMX-R-019-SCFI-2011 (June 4, 2011).
  • NOM-018-STPS-2000 remains in force.
  • Dual labeling & SDS’s result
  • Companies importing/ exporting products to and from countries in Europe, Asia & South America are required to comply with both NOM 018-STPS-2000 & GHS
  • ANIQ (Associacion Nacional de la Industria Quimica) requested authorization from the Labor Secretariat for an alternate procedure to comply with NOM 2000 through the GHS NMX-R

Brazil – Implemented for substances:

  • Pure substances (GHS classification, labeling & SDS) mandatory as of Feb 2011.
  • Mixtures mandatory as of June 1, 2015

GHS Status in Europe & Around the Globe

Looking to Europe and the ROW, 27 EU countries + 3 candidate countries + 3 EEA countries. The previous European system, HSID, can no longer be used for Substances.  While it can still be used for Mixtures, Manufacturers/ Producers/Distributors cannot apply both systems on labels.

Every SDS must display all required information in both systems until June, 1st – 2015.

Also, the original CLP regulation is based on the 2nd edition of the Purple Book.  This past March a second technical adaptation, regulation 286/2011 was published, so now CLP is fully based on the 3rd edition of the Purple Book

This Technical Adaptation gives: New additional combined “H” phrases

Some exemptions in term of the usage of certain pictograms

The size of each pictogram is more specifically specified in regards of the size of label. No new things but more precise.

27 EU Countries – Implemented under Regulation 1272/2008

  • CLP is mandatory for 4,500 SUBSTANCES as of December 1, 2010
  • CLP will be mandatory for all MIXTURES on June 1, 2015
  • 2ND technical adaptation; Regulation 286/2011

Australia: Implemented (Dec. 2016 deadline) ; China: Implemented; Japan: Implemented

67 countries globally – at least partially implemented:  See UN website: http://live.unece.org/trans/danger/publi/ghs/implementation_e.html

OSHA’s Final Ruling on GHS

OSHA has updated its Hazard Communication Standard (HCS) to align with the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS).

Modifications will reduce costs and burdens while protecting employers and employees.

Modifications include:

  • Revised criteria for classification of chemical hazards
  • Revised and standardized labeling requirements
  • A specified format for safety data sheets
  • Requirements for employee training on labels and safety data sheets

Impact of GHS for U.S. Businesses

  • 880,000 hazardous chemicals are currently used in the U.S.
  • Hazard Communication affects 43 million American workers in over 5 million workplaces.
  • GHS will prevent 500 injuries/illnesses and 43 deaths per year, equaling a total of $250 million in reduced health and safety risks.
  • Costs per year will total $201 million
    dollars
    to comply with revisions to
    the HCS.
  • Future net benefits are estimated at $556 million dollars per year.
