  • Silica Respirable crystalline silica (RCS): Tackling

    Silica Respirable crystalline silica (RCS) Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete In the workplace these materials create dust when they are cut, sanded down etc Some of this dust may be fine enough to reach deep inside the lung, this is known as respirable crystalline silica (RCS) and can cause harm to healthRESPIRABLE CRYSTALLINE SILICA THE DUST LAMP An easy, qualitative way of assessing the amount of airborne dust is using a dust lamp – sometimes called a ‘Tyndall beam’ – to illuminate the very fine dust that would otherwise be invisible to the naked eye The process is simple – if you shine a bright light through the dust cloud while arranging a screen to obscure the direct lightRESPIRABLE CRYSTALLINE SILICA: THE FACTSWhat is respirable crystalline silica (RCS)? Crystalline silica is a natural substance found in stone, rocks, sand and clay, as well as products like bricks, tiles, concrete and some plastic composites When these materials are worked on, for example by cutting or drilling, the crystalline silica is released as a very fine dust which can be breathed in This dust is one of the oldest workplaceRespirable crystalline silica (RCS) – Workers Health

    27/01/2020· Respirable crystalline silica is a hazardous substance that can have serious impacts on people’s health Therefore, RCS has a set Workplace Exposure Limit (WEL) to protect the health of workers The WEL represents the legal, safe maximum concentration that workers can be exposed to over the stated timeframeHow much Respirable Crystalline Silica Dust does it take to cause damage? A small amount of RCS can create a health hazard In 2006 the HSE set the Workplace Exposure Limit (WEL) for RCS of 01 mg/m3 expressed as an 8hour timeweighted average (TWA) The WEL as per the HSE is "A Workplace Exposure Limit is the maximum concentration of an airborne substance, averaged over a referenceRespirable Crystalline Silica (RCS) InDepth GuideRESPIRABLE CRYSTALLINE SILICA (RCS) The All Party Parliamentary Group (APPG) for Respiratory Health has urged the Government to take action to prevent the ‘next asbestos’ from taking more lives in the UK The APPG and notforprofit organisation Building and Civil Engineering (B&CE)’s joint report, Silica – the next asbestos?, examines the danger posed by respirable crystalline silicaRespirable Crystalline Silica rmt
