The Advisory Committee on Safety and Health at Work has published an opinion on an occupational exposure limit (OEL) for diisocyanates.

The details are as follows:

  • 20 µg NCO/m3 as STEL and 10 µg NCO/m3 as TWA at the date of adoption of the amendment of the Chemical Agents Directive

  • 12 µg NCO/m3 as STEL and 6 µg NCO/m3 as TWA on 1 January 2029.

The European Commission will now adopt a legislative proposal for an OEL, very likely based on the recommendation of the Advisory Committee on Safety and Health at Work. The adoption of the OELs is expected for 2022 or 2023.
