Crystalline silica

What is crystalline silica?

Respirable crystalline silica (RCS) can be found in different crystallographic forms, the most common of which are quartz, tridymite and cristobalite. It is the respirable fraction of the powder (the finest) that poses a problem due to its adverse effects on health. In fact, these small particles can deeply penetrate respiratory equipment.

This is the reason that maximum exposure limits to RCS have been set in every European country. In Belgium, RCS contents are limited to:
