Directive 2019/1831 - indicative occupational exposure limit values

of 24 October 2019 establishing a fifth list of indicative occupational exposure limit values pursuant to Council Directive 98/24/EC and amending Commission Directive 2000/39/EC

The list is based on Council Directive 98/24/EC concerning the protection of the health and safety of workers from the risks related to chemical agents in the workplace.

Indicative occupational exposure limit values (IOELV) are health-based, non-binding values, derived from the most recent scientific data available and taking into account the availability of reliable measurement techniques.

For any chemical agent for which an IOELV has been set at European Union level, Member States are required to establish a national occupational exposure limit value. They also are required to take into account the Union limit value determining the nature of the national limit value in accordance with national legislation and practice.

Member States shall bring into force the laws, regulations and administrative provisions necessary to comply with this Directive by 20th May 2021 at the latest.

IOELVs are established in relation to a reference period of 8 hours (considering a time-weighted average) and  referred to as long-term exposure limit values, and for certain chemical agents, these relate to shorter reference periods, in general 15 minutes (also time-weighted averages), referred to as short-term exposure limit values, to take account of the effects arising from short-term exposure.

The Directive establishes limit values for the following chemical agents:

2-Phenylpropane (Cumene)
sec-Butyl acetate
Isobutyl acetateIsobutyl acetate
Isoamyl alcohol
n-Butyl acetate

Skin absorption feature of three substances is noted.

2-Phenylpropane (Cumene) was already listed in the Annex to Commission Directive 2000/39/EC. The establishment of a new indicative limit value was recommended by SCOEL. The published value will be deleted from the Annexes to Commission Directive 2000/39/EC on 20th May 2021.
