On 9 October 2017, ECHA will launch a public consultation on scientific evaluation occupational exposure limits (OELs) for acrylonitrile, benzene, and nickel and its compounds. ECHA is inviting comments on the scientific underpinning for the OELs as well as on the draft opinions of the Committee for Risk Assessment. The opinions are to be sent to the Commission by 28 March 2018. Due to the strict timeline, the public consultation takes only four weeks and will end on 6 November. ECHA makes this pre-announcement to help stakeholders prepare to give comments.
