- Indicative limit value
law of the European Union, indicative limit values, more exactly indicative occupational exposure limit values (IOELVs), are human exposurelimits to hazardous substancesspecified by the Council of the European Unionbased on expert researchand advice.
They are not binding on member states but must be taken into consideration in setting national
occupational exposure limits. Some member states have pre-existing national limits lower than the IOELV and are not required to revise these upwards. In practice, most member states adopt the IOELV but there are some variances upwards and downwards. [Dikshith & Diwan (2003) "p."191] [Walters & Grodzki (2006) "pp"53-54]
A system of IOELVs was first introduced in
1980by directive 80/1107/EECbut the first list of 27 substances was not created until directive 91/322/EC in 1991. Member states had until 31 December 1993 to implement national limits. This first list was amended by directive 2006/15/EC in 2006which transferred 10 of the 27 to a different regulatory regime. A second list was defined in directive 96/94/EEC but this was repealed by directive 2000/39/EC.Dikshith & Diwan (2003) "p."189]
1998, directive 80/1107/EEC was repealed and replaced by a new regime under the chemical agents directive ( directive 98/24/EC). The directive defines occupational exposure limit value as "the limit of the time- weighted averageof the concentrationof a chemical agent in the airwithin the breathing zoneof a worker over a specified reference period." [Art.2(d)] Article 3 of the directive led to the creation of the Scientific Committee on Occupational Exposure Limit Valuesto advise the European Commission. [Dikshith & Diwan (2003) "p."190] [ Official Journal of the European Union[http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:31995D0320:EN:HTML L 188, 9.8.1995, p.14-15] ] There have subsequently been two directives establishing further lists of IOELVs: 2000/39/EC and 2006/15/EC. As of 2008, the IOELVs under directive 91/322/EC remain in force but under review.
