A new engineered stone countertop product known as “quartz surfacing,” was created in the late 1980s by combining quartz aggregate with resins to create a product for use in home building and home improvement. The focus of this blog is on silicosis, which has occurred in multiple workers in this industry.
This is a proposal, not a final rule. OSHA encourages the public to participate in development of the rule by submitting comments and participating in public hearings. Your input will help OSHA develop a rule that ensures healthy working conditions for employees and is feasible for employers.
This science blog addresses hydraulic fracturing or “fracking."Initial hazard assessments identified exposure to crystalline silica during hydraulic fracturing as the most significant known health hazard to workers and this has been the focus of the NIOSH study. to date.
This month's NIOSH Science Blog discusses the history and continuing problems associated with silica exposure.
At least 1.7 million U.S. workers are exposed to respirable crystalline silica in a variety of industries and occupations, including construction, sandblasting, and mining. Silicosis, an irreversible but preventable disease, is the illness most closely associated with occupational exposure to the material, which also is known as silica dust. Some studies also have linked respirable crystalline silica with risks for lung cancer and some auto-immune diseases.
Silicosis is a disabling, nonreversible and sometimes fatal lung disease caused by overexposure to respirable crystalline silica. More than one million U.S. workers are exposed to crystalline silica, and each year more than 250 die from silicosis.
