What is the status of respirable crystalline silica regarding EU occupational safety and health legislation?

Currently, there is no European Limit value addressing respirable crystalline silica exposure. The EU Commission has issued a proposal on 13 May 2016 [2016/0130(COD)] to include “work involving exposure to respirable crystalline silica dust generated by a work process” in Annex I of the Carcinogens and Mutagens Directive (2004/37/EC). It proposes the establishment of a binding occupational exposure limit at 0.1 mg/m³ (respirable fraction, 8h TWA) in Annex III – limit value approved by the tripartite Advisory Committee for Safety and Health.

'Process generated' substance means for example “dust created by work processes such as mining, quarrying, or tunneling or cutting, crushing or grinding of silica-containing materials such as concrete, bricks, or rocks”, as explained in the European Commission Press Release IP/16/1656.
