Appendix A. Substance Classification and Labelling under REACH

Appendix A Substance Classification and Labelling under REACH Classification and labelling are used to communicate hazards associated with substances through their use on packaging and in safety data sheets. The European Regulation governing classification and labelling is Regulation 1272/2008, known as CLP 2008. (CLP stands for classification, labelling, and packaging). This Regulation replaces the previous legislation (Dangerous Substances, DSD, and Dangerous Preparations, DPD) 1 and brings the European Union classification and labelling in line with the globally harmonised system (GHS) of classification and labelling. Classification under CLP 2008 has been subject to a long transition period. Substances are no longer in the transition period, so have to be classified according to CLP. Until 2015 they must also be classified according to DSD, but labelled and packaged according to CLP alone. However, the transition for mixtures (previously called preparations) does not end until 1 June 2015. Both DSD and DPD will be fully replaced by CLP 2008 from 1 June 2015. In summary: Substances: Until 1 June 2015: must be classified according to CLP and DSD. Label and package according to CLP. From 1 June 2015: must be classified, labelled, and packaged according to CLP. Mixtures (formerly preparations): Until 1 June 2015: must be classified according to DPD, may be classified according to CLP. May be labelled and packaged according to DPD; if classified according to CLP may be labelled and packaged according to CLP. 1 CLP 2008 is a Regulation, so applies directly to Member States. Both DSD and DPD have to be enacted in Member States legislation; in the United Kingdom this is currently CHIP4. CHIP 4: Chemicals (Hazard Information and Packaging for Supply) Regulations 2009.

318 Appendix A: Substance Classification and Labelling under REACH From 1 June 2015: must be classified, labelled, and packaged according to CLP. For mixtures already in the supply chain, re-labelling, and re-packaging may be postponed until 1 June 2017. The CLP Regulation sets out standard phrases and pictograms that are used on labels and in safety data sheets to warn consumers of the hazardous properties of a substance. From time to time, as classifications of substances are reviewed, and when there are changes to the GHS, Adaptations to Technical Progress (ATPs) are issued. REACH registrations have to include classification and labelling requirements. As information is gathered and assessed, and new data generated, the data may demonstrate that there are hazards associated with the substance that are not covered by any existing classification and labelling. If this occurs then self-classification based on the data available is needed. Classification and labelling requirements are related to the hazard(s) of a substance and may include classification for physico-chemical (e.g. flammability, explosivity), human health (e.g. acute toxicity, corrosive, irritant, sensitising, carcinogenic, mutagenic), and environmental (e.g. aquatic acute and chronic toxicity) hazard classifications. The hazard classes are set out in Annex I of the CLP Regulation. The CLP Regulation and the subsequent ATPs apply to substances and to mixtures, previously dealt with under separate legislation (DSD and DPD). The legislation sets generic concentration limits (Table A.1) below which a substance does not have to be taken into account when considering the classification of a mixture including that substance. For some hazards and substances, specific concentration cut-off values may be set. In most cases the requirement is to determine impurities to the 1% w/w level unless they are Acute Toxicity Category 1 3 or Hazardous to Aquatic Environment Acute Category 1 and/or Chromic Category 1. In these cases the concentration needs to be stated to 0.1% w/w. A specific concentration limit will generally be set when reliable scientific information indicates that the hazard of a substance will be evident at levels below the generic concentration limit. In exceptional circumstances a specific concentration limit that is greater than the generic concentration limit may be set where there is reliable and conclusive evidence that the hazard of a classified substance is not evident at a level above the generic concentration limit. Table A.1 Generic cut-off values. There are some endpoints with different concentration cut-off values. Generic cut-off values (%) Acute Toxicity Category 1 3 0.1 Category 4 1 Skin corrosion/irritation 1 Serious damage to eyes/eye irritation 1 Hazardous to aquatic environment Acute Category 1 0.1 Chronic Category 1 0.1 Chronic Category 2 4 1

Appendix A: Substance Classification and Labelling under REACH 319 Generic concentration limits vary between different hazard categories and can be found in the relevant health hazard sections of Annex I of CLP 2008. Classification for the environment takes into account both long-term and short-term testing; classification for chronic toxicity may be based on short-term or long-term data. Previously, only short-term toxicity was taken into account in aquatic classification. This change was introduced in the second ATP to CLP 2008. In addition, substances that are readily biodegradable may be classified in chronic categories 1 2. For substances that are very hazardous to the aquatic environment, that is classified as Acute or Chronic Category 1, with acute toxicity below 1 mg/ml or chronic toxicity below 0.1 mg/ml (not readily biodegradable) or 0.01 mg/ml (readily biodegradable), multiplying (M) factors must be set. They are used to give increased weight to the acutely toxic substance when calculating the toxicity of a mixture. M-factors are used instead of specific concentration limits when calculating the classification of a mixture that includes very hazardous properties. A.1 Important Differences There are some important differences between the old classification under DSD and DPD and labelling and CLP. Some of these are to do with nomenclature: preparations are now referred to as mixtures; risk (R) phrases are replaced by hazard (H) phrases; safety (S) phrases are now precautionary (P) statements. There have been important changes in the approach to physical chemical hazards under CLP 2008 compared to the previous legislation. Classification for physico-chemical hazards includes more categories than the previous legislation, allowing greater differentiation between hazards. A new type of classification for human health has been introduced: specific target organ toxicity (STOT). This may be single exposure (SE) or repeat exposure (RE). For example, from acute toxicity data a substance may have an acute toxicity classification based on concentrations causing death, and a STOT SE classification, where effects to a specific organ are observed, especially where these do not lead to fatality. However, a substance should not receive two classifications from a single effect, so care should be taken when applying the criteria. STOT RE is based on repeated exposure and like STOT SE has several categories, and again double classification should be avoided: effects that lead to a reproductive toxicity classification would not also lead to classification as STOT RE based on reproductive effects. Subcategories now exist for sensitisation; both skin and respiratory sensitisers may be classified as either: 1A, strong sensitisers, or 1B, other sensitisers, where there is sufficient information for this to be distinguished. If there is insufficient evidence to decide on a subcategory, but there is evidence of sensitisation, then substances are classified as Category 1. There are concentration limits that apply to these classifications: tables with the criteria can be found in Regulation (EU) No 286/2011 amending CLP 2008. The second ATP (Regulation EU 2011/286) introduced new classification criteria for chronic aquatic hazards, concentration limits for sensitisation and classification for substances damaging to the ozone layer.

A multi-lingual glossary of terminology is available on the ECHA web site (ECHA, 2013). This includes definitions of substance names, technical terms and hazard phrases, and includes terms used in previous legislation. The translation of old risk phrases into hazard phrases is not necessarily straightforward, as the criteria are not necessarily the same. For example, the cut-offs for acute oral toxicity classification have changed and classification specifies the route of exposure. Guidance on application of the classification criteria is available from the ECHA web site. The guidance is reviewed and updated periodically, so it is necessary to make sure that the most up-to-date guidance is used. To ascertain existing classifications of substances it must be remembered that changes to CLP in the ATPs include new classification. Existing classifications can be found in the Regulation and the ATPs, and they are available in excel format from the Institute for Health and Consumer Protection (IHCP; Ex-ECB) (IHCP, nd). At the time of writing the Excel tables do not include changes from the third ATP.

Mists are liquid droplets of a substance or mixture suspended in a gas (usually air), generally formed by condensation of supersaturated vapours or by physical shearing of liquids. Dusts and mists generally have sizes ranging from less than 1 to about 100 μm (Tables A.13 A.15). A.2.1.6 Table A.16 A.2.1.7 Aspiration Hazards Skin Corrosion/Irritation Corrosion is the destruction of skin tissue, namely visible necrosis through the epidermis and into the dermis in at least one of three tested animals after exposure up to four hours. Corrosive reactions are typified by ulcers, bleeding, bloody scabs and, by the end of observation at 14 days, by discoloration due to blanching of the skin, complete areas of alopecia and scars or if the results are based on the results of a validated in vitro test or if the results can be predicted, for example from strong alkali or acid reactions indicated byaph< 2or> 11.5. Measurement of ph alone may be adequate but assessment of acidic or alkali reserve is preferable; methods are needed to assess buffering capacity (Table A.17).

Guidance dose/concentration range values are provided below in order to help in classification. oral, rat > 10 < 100 mg/kg (body weight)/day; dermal, rat or rabbit > 20 < 200 mg/kg (body weight)/day; inhalation, rat (gas) > 50 < 250 ppm/6 h/day; inhalation, rat (vapour) > 0.2 < 1 mg/l/6 h/day; inhalation, rat (dust/mist/fume) > 0.02 < 0.2 mg/l/6 h/day. In exceptional cases human evidence can also be used to place a substance in Category 2 (Table A.21). A.3 Specific Target Organ Systemic Toxicity Single Exposure The route of exposure could be added to the hazard statement if it is conclusively proven that no other route of exposure cause the hazard (Table A.22).

A.3.1.1 Substances Toxic for Reproduction s H360 and H361 indicate a general concern for both the reproductive properties related to fertility and developmental effects (Table A.24).

Appendix A: Substance Classification and Labelling under REACH 339 A.4 Harmonised Classification and Labelling For substances, but not for mixtures, harmonised classification and labelling may be proposed. Harmonised classification and labelling may be proposed by anyone in the supply chain (manufacturer, importer or downstream user) as well as by Member States. The process of harmonising classification and labelling is undertaken to protect human health and the environment while at the same time ensuring competitiveness. Usually classification and labelling is harmonised for substances with severe hazards, such as CMRs. Proposals of harmonised classification and labelling are made on a case-by-case basis by the ECHA Committee for Risk Assessment (RCA). The RCA prepares ECHA opinions on risks to human health and the environment on: Harmonised classification and labelling Restriction Authorisation. The final decisions on all these are taken by the European Commission. References CLP (2008) CLP-Regulation (EC) No 1272/2008.
