Activities that generate RCS dust
High-energy processes, such as crushing, sawing and grinding cause the crystalline silica to break apart into fine, respirable particles – RCS dust.

Dynamic activities, such as transporting, bagging and mixing can also cause crystalline silica particles to become airborne. As they are so small and light, RCS dust can remain airborne for days and, when captured by air currents, the dust may never settle.
Across various different industries which use materials and processes that create RCS dust, dust generating activities include (but are not limited to):
