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. It recommends the establishment of a binding OEL of 0.1 mg/m³. The European Parliament's Employment Committee has voted the Ulvskog draft report which proposes a RCS BOELV of 0.05 mg/m3, with a transition value of 0.1 mg/m3 until 10 years after entry into force - to be reviewed 5 years after entry into force. The trilogue between the European Parliament, the Council and Commission is expected to start mid-March 2017.
