Crystalline silica is an essential component in a multitude of materials used in industrial production and life. Respirable crystalline silica (RCS) is the respirable dust fraction of crystalline silica which enters the body by inhalation. Although crystalline silica is ubiquitous in nature, the inhalation of RCS may constitute a hazard to workers. Currently, there is no harmonized European binding Occupational Exposure Limit (BOEL) for RCS exposure. However, most European Member States have already set national RCS OEL values. The European Commission issued a proposal on 13 May 2016 to include work related exposure to RCS dust under the Carcinogens and Mutagens Directive. On 11 July 2017, the COREPER voted on an agreement reached by the Council presidency, the European Commission and the European Parliament. The new text must now be formally adopted by the Council and the European Parliament. The directive sets exposure limits for a further 11 carcinogens in addition to those covered by the existing 2004 directive, including a BOELV for Respirable Crystalline Silica generated by a work process at 0.1 mg/m³. Article 18a specifies that the European Commission will evaluate the need to modify this limit value as part of the next evaluation of the implementation of the Directive.
