UN GHS Revision 8: What Changes to Expect

Little Pro on 2018-08-31 Views:  Update:2018-08-31

The UN Sub-committee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) has published its latest report in Aug 2018 which includes proposed changes to the 7th edition of UN GHS (GHS revision 7). In this article, we will give you a summary of what changes to expect in GHS revision 8.

Change of classification criteria for aerosols

Aerosols will be classified in one of the three categories of this hazard class, according to Table 2.3.1, depending on:

  • – their flammable properties;
  • – their heat of combustion; and
  • – if applicable, test results from the ignition distance test, the enclosed space ignition test and the aerosol foam flammability test, performed in accordance with sub-sections 31.4, 31.5 and 31.6 of the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.”

The new GHS classification criteria for aerosols is listed as follows.

Minor changes regarding precautionary stable for skin irritation and serious eye damage

A number of hazard classes provide sub-categories which can be adopted by competent authorities and by industry where the necessary data is available, e.g. “skin corrosion/irritation” categories, 1, 1A, 1B and 1C. However, the presentation of the precautionary statements in sections 2 and 3 of Annex 3 does not always reflect this accurately. 

To enable appropriate allocation of precautionary statements for skin corrosion category 1 as well as for sub-categories 1A, 1B and 1C, existing entry ‘1A, 1B, 1C’ in column 4 of Tables A3.2.2, A3.2.3, A3.2.4 and A3.2.5 with ‘1, 1A, 1B, 1C’.

To enable appropriate allocation of precautionary statements for serious eye damage/eye irritation as category 2 as well as for categories 2A and 2B,   existing entry ‘2A, 2B’ in column 4 of Tables A3.2.2 and A3.2.3 will be replaced with with ‘2/2A, 2B’ or with ‘2/2A’ as appropriate.

New precautionary pictograms for “keep out of reach of children”

The following examples convey the meaning of precautionary statement P102 “Keep out of reach of children” and may be used to convey information in more than one way according to sections 1.4.4.1 (a) and A.3.3.1.8. One pictogram is from AISE while the other one is from JSDA. It will be important for the labelling of chemical products supplied to the public.

New labeling example for sets or kits

A new labelling example for sets or kits will be added. Generally a set or kit contains two or more small removable inner containers. Each inner container contains different products which can be hazardous or not hazardous substances or mixtures. This new example illustrates ways to label sets or kits where the manufacturer/supplier or competent authority has determined there is insufficient space to place together on each inner container within the kit.
