Abstract:
Inhalation of "respirable crystalline silica" (particles size less than 5 micron [0.2 mil]) can result in silicosis and lung cancer. These small dust particles can be created by chipping, drilling, grinding, diamond polishing, and sawing materials containing crystalline silica, such as concrete and stone. The new OSHA regulations regarding silica exposure for construction that went into effect on September 23, 2017, and their implementation by tool manufacturers, are discussed.
