Sub-Committee of Experts on the Globally Harmonized

    System of Classification and Labelling of Chemicals

Eighteenth session

    Geneva, 9 11 December 2009

    Item 3 of the provisional agenda


    Hazard communication for supply and use of aerosols

    Transmitted by the experts from United Kingdom and FEA


    1. At the last session of the Sub-Committee, United Kingdom submitted an informal document UN/SCEGHS/17/INF.4 (also submitted to the SCETDG as UN/SCETDG/35/INF.11) proposing that aerosols should not fall within the scope of Chapter 2.5 of the GHS, Gases Under Pressure.

    2. The Sub-Committee of Experts on the Transport of Dangerous Goods was of the view that aerosols should not fall within the scope of chapter 2.5 of the GHS (gases under pressure), although the proposal was not agreed by the UNSCEGHS. However most experts did agree that the pictogram for gases under pressure should not be required for aerosols falling within the scope of the definition of gases under pressure, and that further work on the development and harmonization of hazard and precautionary statements applicable to these aerosols was needed. Some experts proposed that the precautionary phrases which are currently being used by different regulatory regimes all over the world be also taken into account. 3. Germany, United Kingdom and EIGA have jointly submitted the working document ST/SG/AC.10/C.4/2009/9 ‗Pictogram for gases under pressure‘ and propose to remove the

    pictogram "gas cylinder" for the purposes of supply and use from the GHS.

    4. The category ‗Flammable Aerosols‘ was agreed in December 2002 and added to the

    fourth edition of the Manual of Tests and Criteria and into Chapter 2.3 of the ‗Purple Book‘ in 2003. That work included consideration of ‗non flammable‘ aerosols which are not required to

    be classified. The subcommittee now, however, is returning to the subject in the context of another ‗new‘ GHS category, ‗gases under pressure‘ which was discussed and developed in parallel with the work on aerosols. As a result the experts from UK and FEA believe there remains a lack of clarity in proposed labelling requirements for non-flammable and flammable aerosols.

    5. The experts from United Kingdom and FEA suggest that the discussion should centre on the following points:

    - The agreed labelling provisions for flammable aerosols already include phrases

    which are specific to all aerosols (not only to flammable ones). For consistency,

    the phrases could be applied to all aerosols. If the Sub-Committee considers that

    those phrases need adaptation, consistency must be maintained for flammable


    - To ensure that statutory warnings remain easy to read, understand and apply, all

    labelling requirements related to aerosols (flammable and non-flammable aerosols)

    should be kept together in Chapter 2.3 (flammable aerosols). Aerosols would then

    be exempted from the scope of Chapter 2.5 (gases under pressure).

    - The agreed labelling provisions for flammable aerosols in Chapter 2.3 (flammable

    aerosols) have proven to be effective within Europe for more than a decade

    (corresponding to around 70 billion units). There is no justification or need for

    additional labelling requirements on flammable aerosols.

    - For non-flammable aerosols sets of warning phrases have been in place

    worldwide e.g. in Europe for 35 years. There is no indication that any additional

    consumer information is necessary for non-flammable aerosols.

    6. The warnings in use in Europe are similar to those used elsewhere around the world. These include warnings which apply to all aerosols, flammable or not. Please find below some findings on different regulatory regimes all over the world for non-flammable aerosol consumer products. The labelling provisions related to flammability are generally simply added onto these standard warnings. Please note that several countries have not yet implemented the GHS (i.e. the UN classification scheme for flammable aerosols) in their national consumer products legislation.

7. Based on the above elements, the experts from UK and FEA suggest the following

    consistent labelling provisions for both flammable and non-flammable aerosols:

8. Aerosols for the general public will additionally be labelled with P102 ‗Keep out of

    reach of children‘.

    9. This would be in line with the intention of the various legislations around the world which clearly have a similar purpose.

    10. If agreed by the Sub-Committee, the experts UK and FEA will be pleased to convert this informal proposal into a working document including all necessary editorial changes for approval at the next Sub-Committee session.
