The cutting, grinding, and polishing of stone (, granite) without proper dust controls can generate high levels of silicacontaining dust. Breathing in this fine dust can cause a serious lung disease called silicosis. This document will help employers develop an exposure control plan (ECP) for work involving the cutting, grinding, and polishing of stone containing crystalline silica ...
cutting and grinding can get deep into the lungs. Most concrete and masonry products contain large amounts of sand. When you inhale the dust, silica particles scar your lungs, causing a disabling, irreversible, and incurable lung disease called silicosis. The good news is that silicosis is 100% preventable. You can work with silicacontaining materials in ways that do not result in exposure to ...
09/06/2021 · Research work was performed in Sokoto, Nigeria, with 56 cement mill workers having a mean of ± years of cement dust exposure and 96 subjects unexposed to the dust in 2007. The lung function parameters were observed and analyzed. It was noted that Forced Expiratory volume in one second and Vital capacity were reduced significantly in cement dust exposed workers compared to .

· Workers can be affected from a variety of illnesses caused by dust they inhale in their work environments. For practical purposes, we limit this document to dust. We do not take into consideration combined effects arising from exposures to dusts, gases, fumes and vapours.
· 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 fabriion taking place. Workers installing stone benchtops that have been completely fabried in a workshop with .
