Globally Harmonized System (GHS) – How ‘Harmonized’ is it really?

GHS stands for the ‘Globally Harmonized System of Classification and Labelling of Chemicals’ and is a U.N. initiative that serves to harmonize three main components of industrial chemical regulation.

The GHS regulations can be found in a document named the ‘Purple Book’ where it discusses the different types of classifications, signal words, hazard and precautionary statements, SDS format, and the 9 hazard pictograms (depicted below).

However, GHS uses a ‘building block approach’, where each jurisdiction involved can adopt certain regulations, and decide not to adopt others. For example, the US Occupational Safety and Health Administration’s (OSHA) Hazcom 2012 regulation decided not to adopt any environmental hazard groups put forward in the U.N GHS initiative. 

Furthermore, each jurisdiction is allowed to include non-GHS rules; which are not found in the Purple Book. These jurisdiction specific regulations must also be complied with. Examples of these include the State of California’s ‘Prop 65’, and the EU SDS Format 453/2010 regulation.  This means that the GHS IS NEITHER GLOBAL, NOR HARMONIZED. Just because an SDS is GHS compliant in one jurisdiction does not mean it will be compliant in another GHS jurisdiction.

Testimonial

I just wanted to take a moment to say how we value the compliance service we have received from Nexreg. In the past two years our company has been faced with many challenges related to the sales of hazardous products in the US and Canada and Nexreg has been an excellent resource to help us ensure compliance to the ever changing regulatory environment.
