The Health & Safety Executive (HSE) has carried out a detailed review on crystalline silica and published it as two documents in their Hazard Assessment Document series; both documents are reviewed here. Hazard Assessment Documents are produced to facilitate the development of a regulatory position on a specific health-related issue. Phase 1 of this HSE project addresses the issues of variability of fibrogenicity and quality of silicosis exposureresponse data, while Phase 2 reviews the evidence with regard to carcinogenicity of respirable crystalline silica (RCS).
The first document deals with the basic yet complex question of whether all RCS exposures are equally fibrogenic, regardless of form or other characteristics. A familiar topic of debate in the silica policy arena is whether a particular crystalline silica-containing dust, e.g. dust generated
