Some of the oorrxnon occupations or <br />types of workers at risk of sJca disease due th cystallinesilica dust <br />exposure tndude: <br />» Sandblasfirw r Sand6ksters <br />» Shlm~ard Workers <br />a Mining !Miners <br />. Foundry Workers <br />a SEonecukers <br />x f'otffirs/Ceramic Workers <br />a Tunnel Workers <br />r Rock Drillers <br />a Road & BuOding Construction <br />a Glass Workers <br />x quarry Workers <br />Bak to Tco <br />Sandbhesfing Disease. Stlica Disease • Higher Rink <br />peeupafions <br />The fnllowirg ocarpations ere discussed in furtherdetail bepuse <br />lney pose the greatest rtsks of the pneumoconiosis silicosis, or <br />slice disease. These occupations pose the highest crystalline sBip <br />dust exposure kevels, are pertonnetl In goody ventilated areas, and <br />surnound ttta worker In a cloud of silica dust for prdonged pedods. <br />Sandbiasling -Sandblasting Disease <br />There is a reason chat silVeosis is wmmonty refened to as <br />sandblasting disease. Sandblasting is one of the highest risk <br />occupations when it mores W silicosis and crystalline silica dust <br />exposure. One of the main reasons is the high concentration of <br />quartz or other high crystalline slice wrAent minerals in the <br />abrasive sands used in sandblasting operations. Roughly 5 percent, <br />or 100,000, of the warkers in the United States that are exposed tc <br />crystalline silica dust on the job are employed as sandblasters. <br />Many other acaepaUons irtvotve sandblastng on a partdma heels. <br />Sandblasting is typic~ly used la dean ar remove anything from <br />automobfie paint to sand from famdry castings. Sand (often <br />containing high rystalline slice concentration} is forced inm a high- <br />pressure stream with compressed air or steam and used as an <br />abrasive agent for many types dcleaning snd surface preparation <br />jobs. Silica sand can break tlown to very small partides during <br />sandblasting operations. This freshly ground silica tlust lands to <br />lead Oo the quicker-to-progress acute and accelerated forms of <br />sliicosis or sandbtasistg disease. <br />SNdfes have shown that many sandblasters Fnve already died of <br />silicosis or silica disease. Unfodunataly, these studies also project <br />that many more will likely die of sandblasting disease caused by <br />inhalation of extremely dangerous levels of erystalltre silica dust <br />Others will likely die of some of the complications related io <br />silicosis, Tike lung cancer and tuherculos's. <br />http:liwww.silioosisclaims.com/about.htmt 4I1OY1OO7 <br />
