Every two years, the UN publishes a revised version of the “purple book,” is the official text of GHS standards. Following 2013’s version five, next version will be adopted and implemented in 2016. Reports generated after the 27th session of the UN Sub-Committee of Experts on GHS generated widespread speculation on the potential amendments that will be made to the purple book.
We expect changes for the sixth version of the “purple book” to include:
Two New Hazard Classes:
1. Desensitized Explosives: Substances and mixtures that are combined or diluted with water or alcohol to suppress their explosive properties. Desensitized explosives are expected to be added to the existing six divisions of explosive categories, which are categorized asphysical hazards.
2. Pyrophoric Gases: A new hazard class for pyrophoric gases will likely be added as a subcategory of flammable gasses.
Label Revisions for Small Packages:
A standard GHS label poses a unique challenge for products that are transported in small containers, such as pharmaceuticals and bottles. The new version of the “purple book” will likely clarify requirements for small containers.
OSHA has already addressed these concerns in a recent “Letter of Interpretation” by agreeing to accept an abbreviated version of the regulations on pull-out labels, fold-back labels, tags, or other methods for small packages.
Adoption and implementation of the proposed updates will vary from country to country. It’s imperative to monitor the decisions made by regulatory agencies such as OSHA to ensure you avoid noncompliance consequences.
