Directive 91/322/EEC of 29 May 1991 on establishing indicative limit values by implementing Council Directive 80/1107/EEC on the protection of workers from the risks related to exposure to chemical, physical and biological agents at work is based on Directive 80/1107/EEC, which was repealed and replaced by Directive 98/24/EC.
It sets out indicative limit values for certain chemical substances in its Annex. For any chemical agent for which an indicative occupational exposure limit value is established, Member States must establish a national occupational exposure limit value, taking into account the Community limit value, determining its nature in accordance with national legislation and practice.
The original annex listed limit values for 27 chemical substances. The limit values for 17 of these substances were later on transferred to Directive 2006/15/EC and for 4 of these substances to Directive 2017/164/EU. The current Directive establishes indicative occupational exposure limit values for a reference period of eight hours for the following 6 chemical substances:
Picric acid
Naphtalene
Pyridine
Cresols (all isomers)
Platinum (metallic)
Tin (inorganic compounds as Sn)
