Signal Words, Hazard Statements, Precautionary Statements, Mixtures and Pictograms, CLP regulations.
Just when you thought you understood everything you needed to know about Hazardous Goods along comes a whole new collection of terms to wrestle with. So what is going on?
GHS stands for Globally Harmonised System of Classification and Labelling of Chemicals and is a further step along the path of ensuring that all countries treat hazardous substances in the same way. This step deals specifically with the classification of chemicals. Many of these criteria will be familiar to those working under the current EU system, although in many cases the actual values used to define the hazard category will differ.
Therefore EU companies will notice a number of additional hazard categories for some criteria that indicate a lower degree of hazard.
The system for classifying mixtures will also change, and this is expected to result in a significant increase in the number of mixtures that are classified as hazardous.
These changes will need to be reflected in Safety data Sheets.
Labelling
The content of labels will change significantly. Under GHS, the rectangular orange symbols familiar to those in the EU will be replaced by a new set of pictograms which will be diamond shaped like the transport symbols, but with the symbols in black on a white background with a red border.

In the EU, Indications of Danger will be replaced with Signal Words, while Risk Phrases and Safety Phrases will be replaced with Hazard Statements and Precautionary Statements.
Implementation of GHS
However where it gets interesting is that although this is an attempt to rationalise rules and regulations in reality these may be implemented on an optional basis. Therefore the likelihood is that some countries will include them in their new regulations while others, will not. Thus there will still be some differences between countries, although the foundation on which the classification is based will be the same.
GHS will be progressively implemented worldwide.
In the EU (and therefore the UK), GHS has been implemented through the CLP Regulation (EC) No 1272/2008. (Guidance on how to comply with the provisions of the new Regulation on Classification, Packaging and Labelling of substances and mixtures)
This is going to create huge problems for many companies but there is help out there. We can help you to put a new software package in place to create your new Safety data sheets and new product labels incorporating the new Pictograms.

So in summary:
Mixtures = Preparations
Signal Words = Indications of Danger
(a) Danger means a signal word indicating the more severe hazard categories
(b) Warning means a signal word indicating the less severe hazard categories
Hazard Statements = Risk Phrases
Safety Phrases = Precautionary Statements
Pictograms = Hazard Symbols
CLP = Carriage, Packaging and Labelling regulations
There – it wasn’t too bad was it?
Don’t forget to come back here soon for a brief introduction to REACH, oh sorry forgot to mention that one.
We’d be welcome to hear your comments on this, so please get in touch.
Thanks to NCEC for the simple explanation of GHS which forms the basis for this Blog.
