Directive 2024/869
One year after the publication of the draft, Directive (EU) 2024/869 was published on 13 March 2024, updating the OELs for lead and its inorganic compounds and introducing OELs for diisocyanates for the first time.
This directive entered into force on 2 April 2024 and will apply from 9 April 2026.
Directive 2024/869: lead
According to Regulation 1272/2008 (CLP), lead and its inorganic compounds are important occupational reprotoxic substances. Consequently, the European Parliament and the Council of the European Union decided to establish new biological limit values and lower OELs for these substances.
The new limits for lead and its organic compounds are set at less than a quarter of the values currently in force. In particular, the revised OEL, which will be mandatory by 9 April 2026, is set at 0.03 mg/ m³, as an 8-hour time-weighted average (TWA).
Directive 2024/869: diisocyanates
Directive (EU) 2024/869 brings a significant change by introducing for the first time an OEL value of 6 μg NCO/m³ (thus measured as mass of the isocyanate functional groups NCO) and a short-term exposure limit value of 12 μg NCO/m³, which will become mandatory for diisocyanates by 9 April 2026.
However, a transitional period has been established for diisocyanates until 31 December 2028, during which an OEL of 10 μg NCO/m³ will apply, with an associated short-term exposure limit value of 20 μg NCO/m³.
