Silicosis that develops 5–10 years after first exposure to higher concentrations of silica dust. Symptoms and x-ray findings are similar to chronic simple silicosis, but occur earlier and tend to progress more rapidly. Patients with accelerated silicosis are at greater risk for complicated disease, including progressive massive fibrosis (PMF).
Respirable crystalline silica – microscopic particles of silica can be become airborne and inhaled when cutting, sawing, grinding, or drilling rock or concrete. Silica is used for foundry molds and cores, so exposure can occur when grinding on castings. Fracking uses silica. About 2.3 million individuals in the U.S. are exposed to silica at work.
Exposure to silica can cause Silicosis, which is a fibrosing interstitial lung disease caused by inhaling fine particles of silica, most commonly in the form of quartz or cristobalite. Short-term exposures of large amounts of silica or long-term (10 years or more) exposure of lower levels of silica can cause silicosis.
Florenza Marble & Granite exposed employees to silica levels up to six times greater than permissible, leaving a 31-year worker, his 59-year-old father and a co-worker with silicosis, an incurable ...
The new study estimated that 100,000 workers in the U.S. are potentially at risk of silicosis due to exposure to silica dust. Dr. Jane Fazio, a co-author of the study and a pulmonary specialist at ...
The grinding and sanding of synthetic engineered stone exposes workers to high levels of lung-scarring silica. Experts say the health risk should have been clear long before workers began falling ill.
International Space Station image taken on September 11, 2001, with the smoke plume rising from Lower Manhattan and extending over Brooklyn (Expedition 3 crew). Within seconds of the collapse of the World Trade Center in the September 11 attacks, building materials, electronic equipment, and furniture were pulverized and spread over the area of the Financial District of Lower Manhattan.
[1] [2] Depending on extent and severity, it may cause death within months or years, or it may never produce symptoms. It is usually an occupational lung disease , typically from years of dust exposure during work in mining; [ 5 ] textile milling; shipbuilding, ship repairing, and/or shipbreaking ; sandblasting ; industrial tasks; rock drilling ...
