In 2020, CEN TC137 issued the standard EN 17289:2020 "Characterization of bulk materials - Determination of a size-weighted fine fraction and crystalline silica content (parts 1-3)". This is a method Industrial Mineral Association EU asked for in order to characterize products (bulk materials) based on their size-weighted fine fraction (SWFF) and crystalline silica (CS) content. SWFF is not theoretically overlapping EN 481:1993 but is related to it. It is reasonable to assume that materials potentially containing a lower fraction of silica in SWFF are inherently less hazardous, even from a worker safety perspective. Standard EN 17289:2020 explicitly specifies these concepts. By comparing similar bulk materials, i.e. differing only in particle size distribution and not also in composition, the one with a lower SWFF also poses a lower risk in terms of occupational exposure. The text also discusses the framework established by the EU Directive 2017/2398 regarding occupational exposure limits of workers to carcinogens and the renewed interest regarding the risk agent airborne crystalline silica. Finally, a working hypothesis is proposed for the implementation of the Inail silica database on occupational exposure to respirable crystalline silica.[Abstract appeared in the Journal]
