Workers may be exposed to crystalline silica while cutting, grinding, sanding and polishing stone bench tops and during the installation process. Generally exposure to RCS occurs during manufacture of the stone benchtop rather than during installation due to less cuts and fabrication taking place.
However, cutting, grinding, chipping, sanding, drilling, and polishing natural and manufactured stone products can release hazardous levels of very small, crystalline silica dust particles into the air that workers breathe. Working with ground quartz in the countertop manufacturing industry can also expose workers to dangerous silica dust.
