CPWR's Exposure Control Database can help you anticipate and control worker exposures to silica, welding fumes, lead, and noise This free online tool allows users to enter a construction task, proposed controls, and other variables and obtain a predicted exposure level based on …
In 1974, the United States was poised to adopt a ban on silica sand for abrasive blasting on the recommendation of the National Institute for Occupational Safety and Health (NIOSH), but as discussed in our article on the Silica Rule, political forces hampered adoption, and wet abrasive blasting technology failed to find a foothold in North America
Millions of US 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
Sand blasting is also known as abrasive blasting, which is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a …
