Does this mean that crystalline silica should be classified and labelled as a Carcinogen?

No. It is the producers who are responsible for labelling their products according to the CLP rules, and there is nothing new at this level. General product stewardship mechanisms are valuable for workers’ health protection throughout the whole value chain.

To comply with the CLP Regulation, industrial minerals producers classify quartz (fine fraction) and cristobalite (fine fraction) as STOT RE Category 1 for the silicosis hazard. STOT refers to Specific Target Organ Toxicity. RE refers to “Repeated Exposure”. This industry classification recognizes that the main health effect of long term workplace exposure to RCS is silicosis and that measures to prevent silicosis will also prevent any associated lung cancer risk.
