EU adopts harmonized occupational exposure limits (OEL) for diisocyanates

EU adopts harmonized occupational exposure limits (OEL) for diisocyanates

Economies & Policies

Mar 25, 2024



The European Parliament and the Council formally adopted new exposure limits for diisocyanates and published them in the Official Journal of the European Union. They are welcomed by industry associations ISOPA and ALIPA.

The new regulations set the eight-hour time-weighted average occupational exposure limit (OEL) for diisocyanates at 6µg/m3. Member states have until April 9, 2026 to incorporate the new limits into their national legislation.

Importantly, occupational exposure limits (OELs) will now be consistent across all member states, whereas previously there were different limits. "Establishing a level playing field in the EU is important to ensure a coordinated approach across all EU member states," the associations said.

They added that the new binding limits would require significant investment in the value chain, as noted in the impact assessment attached to the Commission's original proposal. Therefore, they welcome the transition value of 10 μg/m3, which will apply until December 31, 2028.

ISOPA and ALIPA are now planning to publish a practical guide for industry and professionals on how to comply with the new restrictions. This should be rolled out in the next few weeks.
