Version 4.2 Committee for Risk Assessment (RAC) Committee for Socio-economic Analysis (SEAC) Draft Opinion on a Review Report for Chromium trioxide; Sodium dichromate Pre-treatments: Deoxidising, pickling, etching and/or desmutting using chromium trioxide or sodium dichromate in aerospace and defence industry and its supply chains Submitting authorisation holder Boeing Distribution Deutschland GmbH ECHA/RAC/SEAC: [Opinion N] Consolidated version Date: [date of adoption/agreement in RAC and/or SEAC P.O.

Reasons for the need for (at least) a 1215 year derogation are the lead times for legally required class type approval, the required docking intervals for seagoing vessels (5 year period) and the lead times of our 4 R&D programmes, with a timeline of 12 - 15 years, that aim for two solutions: o To find an adequate alternative material to the fluoropolymer FKM; o To realise a full circular solution, by collecting the used seals and recycle them or incinerate them controlled >850 0C (short term) and to start in parallel a R&D program on breaking the crosslinks in FKM by devulcanizing (long term).

PFAS REACH Annex XV Restriction Report 1ST Public Consultation (22 March - 25 September 2023) Commercial Refrigeration, Air conditioning and Heat pumps sub-uses of fluorinated refrigerants - request for exclusion or time unlimited derogation from the PFAS REACH Restriction Proposal Contents Executive Summary..............................................................................................................................2 1.

HFC-152a is not in the scope of the ECHA REACH PFAS proposal. 1 The ECHA REACH proposal states in Table 8 (pages 100-101) that alternatives/substitutes are readily available for MDIs (also known as pressurised MDIs, or pMDIs) and the ban of medical propellants would have "likely very small costs" and would not lead to "additional administrative costs for industry or authorities."
