Occupational exposure to crystalline silica in artificial stone

Respirable Crystalline Silica (RCS) is a hazardous substance with known effects that can be well correlated with exposure levels that still persist in many traditional Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, Silica Minerals Education Coalition

Silicosis prevalence and risk factors in semi-precious stone mining

Background: Underground mining generates large amounts of dust and exposes workers to silica. This study aims to determine the prevalence and predictor factors for benefits of frac sand mining as they pertain to air quality, water quantity, water quality, and reclaiming mines after mining is completed. In Part 2, the authors Environmental Impacts of Industrial Silica Sand (Frac Sand) Mining

CDC Mining Silica Percent in Airborne Respirable

This manuscript analyzes the % of silica in dust samples for the U.S. mining industry collected from 1997 to 2011. In the metal/nonmetal (M/NM) industry, metal and sand and gravel mines In Queensland, Australia, screening of 799 workers in the countertop industry has led to the diagnosis of dozens of cases of silicosis. A report outlining the findings from a screening programme in Victoria, in the south of the country, concluded that the average age at which stonemasons working with artificial stone were diagnosed withSilicosis and the countertop industry The Lancet Respiratory

Safety alert 11/2018 Stone benchtop workers at risk

Silicosis risks are much greater when working with engineered stone as it contains up to 95% crystalline silica while natural stone contains 5-50% crystalline silica. Fabricating and installing natural manufactured stone industry (the study), was commissioned by SafeWork NSW and published alongside the NSW Dust Disease Register Annual Report 2020-21. The aim of the study was to provide “insight into the burden of silica-related disease in the manufactured stone industry from 2017-2020”.3Silicosis and the manufactured stone industry: an update

Self‐reported disease symptoms of stone quarry workers exposed

In China, an estimated 23 million workers are exposed to silica dust while in India, about 10 million workers are exposed. 1 Similarly, in the United States, 2.3 million workers are estimated to be exposed to silica dust with 1.85 million of them in the construction sector. 2 Recent studies have shown increased morbidity and mortality Health risks of silica exposure for mining industry workers. In a recent study, researchers at University of Illinois Chicago have found a clear link between silica exposure and severe black lung disease in contemporary U.S. coal miners. They found that silica exposure is a driving force behind rising rates of coal workers’ pneumoconiosis.Mining Industry: Lower Silica Dust Exposure Limits and Updated

Concentration, sources and health effects of silica in ambient

Though the prevalent incidence in JCF is rare, the exposure risk is increasing due to silica-generating sources containing quartz as the principal component, such as building and road construction, stone chip industry, mineral crushing and screening, brick kilns, refractories, sand mining and other geogenic sources additive to Background Workers compensated for silicosis outside the mining industry are at an increased risk of developing lung cancer. In the meta-analyses no data from Germany are involved. Furthermore, exposure data are necessary if a threshold value is to be assessed in order to reduce the risk for silicosis and also for lung cancer.

Prevalence and risk factors for silicosis among a large cohort of stone

Objectives High silica content artificial stone has been found to be associated with silicosis among stone benchtop industry (SBI) workers. The objectives of this study were to determine the prevalence of and risk factors for silicosis among a large cohort of screened SBI workers, and determine the reliability of respiratory function testing (RFT) and chest More than 500 stonemasons have been diagnosed with silicosis nationally, but experts say it's 'likely just the tip of the iceberg', with miners, quarry workers and others in the constructionWorkers diagnosed with silicosis after being exposed

Silica and the lung WorkSafe.qld.gov.au

Silica and the lung Crystalline silica is a common mineral found in most rocks, sands and clays. It is present in things like concrete, bricks, mortar, pavers, tiles, cement sheeting, natural stone products and engineered stone slabs. There are three forms of crystalline silica: quartz, cristobalite and tridymite. Material Amount of crystallinemining activities. Miner operators can reduce the amount of silica-containing dust generated by staying in-seam while mining. Cutting sandstone top and/or bottom while mining generates excessive amounts of silica-containing dust.
