Also known as The Purple Book, the standard is used around the world, and more than seventy nations have adopted at least part of it.

The United Nations (UN) has released the Sixth Revision of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Also known as The Purple Book, the standard is used around the world, and more than seventy nations have adopted at least part of it.

In the United States, OSHA's HazCom 2012 is based on the Third Revision, with modifications tailored for U.S .law and OSHA's workplace-safety focus. Less than one year away, June 1, 2016, is the final deadline by which OSHA expects U.S. employers to fully comply with its 2012 final rule revising the Hazard Communication Standard.

What's New with GHS?

New Hazard Class: "Desensitized Explosives"
Additional sub-category in the existing "Pyrophoric Gases" Class
Clarifications in criteria for Explosives, Acute Organ Toxicity, Aspiration Hazards, and Aquatic Environment Hazards
Additional details to be included on the SDS (in Section 9: Physical and Chemical Properties)
Revised Precautionary Statements
New example: labeling small packages (pictured in Annex 7)

What's Not New with GHS?

None of the pictograms or label layouts are changing, and the core of the system is still the same. Visually, there is almost no difference; the changes are mostly on the Classification end, and not the Labeling end.
