The symptoms of silicosis can include a persistent cough, shortness of breath, exhaustion and more. The exposure to crystalline silica can be occupational or non-occupational. Those included making use of more frequent silica sampling protocols and issuing citations and fines for excess silica dust exposures. such as bricks and concrete. Silicosis is an interstitial lung disease caused by breathing in tiny bits of silica, a common mineral found in many types of rock and soil. Dangerous Exposure of Silica Dust with Traditional Tile Removal. Hiring a flooring removal contractor that utilizes traditional removal methods will undoubtedly leave you with large amounts of dust and debris that will necessitate cleanup for months to come. Heavy exposure can cause acute and chronic symptoms to appear even . Generally, it becomes a hazard with repeat exposure. Because silicosis is caused by cumulative or repeated exposure to respirable crystalline silica, it makes sense that we would want to limit exposure as much as possible! Exposure of workers to respirable crystalline silica is associated with elevated rates of lung cancer. Conducting a careful cleanup of the debris created by the demolition is also important. The damage slowly sneaks up, long after a worker has left the dusty worksite. Silica dust exposure can lead to permanent lung damage, and the result may be dangerously low oxygen levels within the blood. A new OSHA safety standard will lower the limit on exposure to silica, to 50 micrograms of respirable crystalline silica per cubic meter of air, averaged over an 8-hour day. The PEL had formerly been an average of 250 micrograms per cubic meter of air over an 8-hour shift. Hello! Symptoms of silicosis may include: Cough Fatigue Shortness of breath Chest pain It can also increase the risk of lung diseases including, tuberculosis, chronic bronchitis, and lung cancer.
