Caroline Raine discusses the forthcoming changes to safety data sheets following the draft publication of the REACH Annex II regulations. The draft regulations are currently undergoing consultation but are expected to be published soon and will require all safety data sheets to be updated by the end of December 2022.

Introduction

The requirement to supply a safety data sheet is from the EC Regulation 1907/2006 on the Registration, Evaluation and Authorisation of Chemicals (REACH). Annex II of REACH lays out the requirements for the compilation of the safety data sheets.

REACH requires that safety data sheets are supplied when:

  • the substance or mixture is dangerous as per the EC Regulation 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP)

  • the substance (not mixture) is classifiable as Persistent, Bioaccumulative and Toxic (PBT) or very Persistent and very Bioaccumulative (vPvB)

  • the substance is included in the list in Annex XIV (being a list of substances subject to authorisation)

  • the mixture is not dangerous but contains:

    • ≥1% by weight (≥0.2% by volume for gases) of any substance posing a health or environmental hazard

    • any substance for which there is a Community workplace exposure limit

    • non-gaseous mixtures containing ≥0.1% by weight of any substance classified as PBT or vPvB.

Earlier this year the European Commission launched a consultation on changes to REACH Annex II.

The main provisions are:

  • to align it with the GHS 6th/7th Revised Editions (particularly section 9);

  • to align it with requirements for nanomaterials;

  • clarify requirements related to poison centres (Unique formula identifiers (UFIs)).

The consultation closed on 10 October 2019 and information can be found on the European Commission website.

The draft has also been notified to the World Trade organisation (WTO) -— G/TBT/N/EU/680.

Changes

Let’s have a look at the changes working through each section of the safety data sheet.

Section 1

The Unique Formula Identifier (UFI) is to be included in Section 1 of the safety data sheet. The UFI is an alpha-numeric 16-character code that is generated from the company’s VAT number and an internal code that has been allocated to the product. There are provisions in place if a supplier is not registered for VAT and there is no VAT number. This code must then be placed on the product label and becomes part of the notification to the poison centre.

The UFI is to be added to Section 1.1:

If the mixture has a unique formula identifier (UFI) in accordance with section 5 of Part A of Annex VIII to Regulation (EC) No 1272/2008 and if a derogation from section 5.2 of Part A of that Annex is applied in accordance with section 5.3 of Part A of that Annex as a result of which the UFI needs to be indicated in the safety data sheet, then the UFI shall be provided in this subsection.

Also, within Section 1.1 there is a requirement if the safety data sheet applies to different forms to declare this “if the product or if the safety data sheet pertains to one or more nanoforms, or substances that include nanoforms, this shall be indicated by using the word “nanoform”.”

Section 2

Within Section 2.3 other hazards — Information shall be provided on whether the substance or mixture meets the criteria for persistent, bioaccumulative and toxic or very persistent and very bioaccumulative in accordance with Annex XIII, whether the substance was included in the list established in accordance with Article 59(1) for having endocrine disrupting properties, and whether the substance is a substance identified as having endocrine disrupting properties in accordance with the criteria set out in Commission Delegated Regulation (EU) 2017/21003 or Commission Regulation (EU) 2018/6054.

Section 3

Section 3.1 — for substances — The specific concentration limit and M-factor for substances included in Part 3 of Annex VI to Regulation (EC) No 1272/2008 or provided to the classification and labelling inventory established under that Regulation shall be indicated, if available. The acute toxicity estimate for substances included in Part 3 of Annex VI to Regulation (EC) No 1272/2008 or determined in accordance with Annex I to that Regulation shall be indicated, if available.

If the substance is registered and it covers a nanoform, the particle characteristics that specify the nanoform, as described in Annex VI, shall be indicated. If the substance is not registered, but the safety data sheet covers nanoforms, the particle characteristics of which have impact on the safety of the substance, those characteristics shall be indicated.

Table 1.1 — List of hazard classes, hazard categories and concentration limits for which a substance shall be listed as a substance in a mixture in subsection 3.2.1 has been updated.

  3. aerosols

  4. oxidising gases

  5. gases under pressure

  6. flammable liquids

  7. flammable solids

  8. self-reactive substances and mixtures

  9. pyrophoric liquids

  10. pyrophoric solids

  11. self-heating substances and mixtures

  12. substances and mixtures, which emit flammable gases in contact with water

  13. oxidising liquids

  14. oxidising solids

  15. organic peroxides

  16. corrosive to metals

  17. desensitised explosives.

And in section 9.2.2 other safety considerations.

Properties, safety characteristics and test results listed below may be useful to indicate as regards a substance or a mixture:

  1. mechanical sensitivity

  2. self-accelerating polymerisation temperature

  3. formation of explosible dust/air mixtures

  4. acid/alkaline reserve

  5. evaporation rate

  6. miscibility

  7. conductivity

  8. corrosiveness

  9. gas group

  10. redox potential

  11. radical formation potential

  12. photocatalytic properties.

Those are the major changes. There are, of course, lots of others: for example, Section 11.2 Information on other hazards — information on endocrine disrupting substances; Section 12.6 endocrine disrupting properties; and section 14.7 Changes from Transport in bulk according to Annex II of MARPOL and the IBC code to “Maritime transport in bulk according to IMO instruments.”

Timescales

The regulations will come into force from 1 January 2020, which will mean that all new safety data sheets will need to be authored taking into account the new requirements. All existing safety data sheets will need to be updated by 31 December 2022.

The timescales are quite demanding and in the consultation period many comments were in relation to the implementation dates. Hopefully the European Commission will include more realistic timeframes in the final version.

Conclusions

  • Please bear in mind this is not a complete summary of the changes and one should always refer to the regulations to ensure compliance.

  • Keep monitoring the situation and look out for the final REACH Annex II to be published.

  • Start to gather your information so that you can update your safety data sheets.

  • Talk to your software suppliers to make sure that the changes are being incorporated into your software templates.

  • Ensure that you update your safety data sheets in good time for the 31 December 2022 deadline.

  • And of course, make sure that any new safety data sheets that you write after 1 Jan 2020 meet the new requirements!
