Concrete grinding, sanding and polishingĪny activity where a high revolution, impact or crushing/breaking type activity is occurring, has a greater potential to release respirable crystalline silica dust into the atmosphere, which when inhaled, can have irreversible health consequences if exposed to the lungs.Commination processes (Including rock crushing and milling mineral samples).Demolition of structures, building and refurbishment.Respirable crystalline dust is also present in numerous construction materials and can become respirable in some of the following example processes. There are numerous work processes that have the potential to release RCS dust either directly or indirectly by disturbing settled materials. TypeĬomposite (engineered or manufactured stone) Silica composition of various rocks and rock products. Materials such as drywall, fibre cement products, some paints, roofing tiles and pavers and stone such as granite, quartzite, sandstone, shale and limestones have potential to contain the crystalline form of silica. It is the crystalline form of silica in these materials that has raised concern in recent years. Silica, or silicon dioxide, is present in quartz, stone, soil, granite, bricks, cement, grout, mortar, bitumen, and also in engineered stone products. What is respirable crystalline silica (RCS) Management should be proactive with an industry focus, in anticipation of increased legislative rigour and statutory guidance. There has been a disturbing rise in the number of workers presenting with silicosis, a condition that has also been known as ‘miner’s phthisis’, ‘grinder’s asthma’ and ‘potter’s rot’. Australia, and other countries, are witnessing a resurgence in diagnoses of silicosis disease in workers in mining, construction and now those who work with engineered stone. The impact of working with Respirable crystalline silica is a topical issue that is receiving increasing attention due to rising numbers of affected workers.
