Summary of New Changes in GHS Revision 8 Update 14.07.2019 On 18 March 2019, the Committee of Experts on TDG and GHS of the UNECE has published approved amendments to the seventh revised edition of UN GHS purple book. These changes are going to be included in the 8th edition of UN GHS purple book (GHS rev. 8) to be published in July 2019. In this article we will summarize what the main new changes are. Change of classification criteria for aerosols Aerosols are to be classified in one of the three categories, according to Table 2.3.1. The category will depend on: - their flammable properties Table 2.3.2: New GHS Classification Criteria for Aerosols
Corresponding hazard statements and pictograms for chemicals under pressure are listed as below.
New precautionary pictograms equivalent to the precautionary statement P102 “Keep out of reach of children” There is a proposal to include in the GHS a pictogram to be used in addition to P102 “Keep out of reach of children”, and a paper proposing a rationalisation and simplification of P201 and P202. Several scientific studies have confirmed that visual representations or pictograms can be recognised more quickly and intrinsically trigger more spontaneous interest than written warnings. One such study concluded that “inclusion of GHS hazard pictograms and precautionary pictograms to SDS and labels may benefit the user”. It is estimated that about 14% of the world’s population cannot read and so the use of simple and intuitive precautionary pictograms can be an effective means to convey essential safe use information on hazardous chemicals. The objective of the proposal is to seek a common way - at the global level - to help reduce the number of incidents where young children come into contact with chemicals, through the adoption of one simple and intuitive precautionary pictogram to convey the message “Keep out of reach of children” (Precautionary Statement P102). This can be achieved by including this precautionary pictogram in s.5 of Annex 3 of GHS. 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 accordingly. One pictogram is from the International Association for Soaps, Detergents and Maintenance Products (AISE), while the other one is from the Japan Soap & Detergent Association (JSDA). It will be important for the labelling of chemical products supplied to the public. Safe use icon “Keep out of reach children used by the AISE and safe use icon developed by the JSDA The intention is to add the precautionary pictograms to the GHS (Annex 3 s.5 after paragraph A3.5.1.). New labelling example for sets or kits It is intended to further improve the examples for sets or kits by adding a new example “Labelling of sets or kits” in Annex 7 of the GHS. Scenario A The set or kit comprises an outer packaging containing the following inner containers. Four cuvettes, each filled with the same substance or mixture (Reagent 1). Two larger containers each filled with another substance or mixture (Reagent 2). The approach is to provide minimum information on each of the inner containers containing hazardous substances or mixtures, and to provide the full GHS label information for each hazardous substance or mixture on the outer packaging. For clarity, the full label information for each hazardous substance or mixture is grouped together on the outer packaging.
