A GB MCL technical report is an independent scientific evaluation of the information submitted under the stand-alone GB MCL process or as part of the EU harmonised classification and labelling process. It sets out whether there is adequate scientific evidence to support a new or revised GB MCL of a substance and what that GB MCL should be. The next batch of GB MCL technical reports is now available for download from the GB MCL publication table (.xlsx). These Technical Reports are for the chemical substances Bixlozone, Solvent Violet 13 and Pigment Red 83, produced under Article 37A of the GB CLP Regulation, following on from the GB MCL proposals produced by the Agency in 2022 and 2023. At the time of publication, the classification and labelling proposed in these technical reports has not been agreed and/or adopted in Great Britain. For information on the next steps in the process, please see our webpage on the GB MCL system. We expect to publish our next batch of technical reports in May 2024. CLP ebulletin alerts will be issued when technical reports are published on the HSE website. If you have any questions or feedback on the GB MCL technical reports, please contact us at: GBCLP.GBMCL@hse.gov.uk Journalists should contact HSEs press office for further information. Deadline: 17 May 2024 The GB MCL process includes the consideration of information gathered from public consultations, conducted by HSE or international bodies such as the European Chemicals Agency (ECHA). ECHA has announced a public consultation on the following proposal for harmonised classification and labelling (CLH): - 1,3-diphenylguanidine (EC: 203-002-1; CAS: 102-06-7). Chemical registered under REACH. Health and environment hazard classes open for commenting.
View the consultation on the ECHA website UK-based businesses with an interest in the proposal are strongly encouraged to share any relevant information. Scientific and technical information should be submitted directly to ECHA using their commenting webform by 17 May 2024. Comments will be published on ECHA's website. If your business is affected by the GB CLP Regulation, please also consider if you are likely to be affected by the classification and labelling proposal and let us know at an early stage if you anticipate any significant impacts or benefits. Information on wider policy and impact considerations can be submitted to HSE at GBCLP.GBMCL@hse.gov.uk. Under the GB CLP Regulation, HSE will consider all published opinions of the Committee of Risk Assessment of ECHA (RAC) before publishing its own Agency Technical Reports and Agency Opinions, so any information you provide will be important in any final GB MCL decision. More information on the new GB MCL systemis available on the HSE website. |
