Engineered stone materials may contain substantially more crystalline silica than natural stone >90%, compared with <45% in granite OSHA/NIOSH Hazard Alert . Tasks such as cutting, grinding, polishing, and drilling can release hazardous levels of silica dust into the air.
As with any silica-containing stone, silicosis can result from breathing dust produced when cutting or processing engineered stone made with quartz. The risk of inhaling quartz dust can be mitigated by taking appropriate safety precautions. Risk of silicosis is high when little or no safety precautions or protective equipment are used.
Silica occurs as a natural component of many materials used or encountered in construction activities. Crystalline silica is present in substantial quantities in sand, sandstone and granite, and often forms a significant proportion of clay, shale and slate. It can also be found in chalk, limestone and other rock and soil.

OSHA’s Silica Rule went into effect on June 23, 2016. Since a portion of the stone industry will be covered under the “construction” standard and others under the “general industry” standard, the following documents and links are provided for quick reference: OSHA Fact Sheet: Construction Standard; OSHA Fact Sheet: General Industry Standard
As its name suggests, engineered stone is designed to overcome some of natural stone& 39;s liabilities. Most of the popular brands of engineered stone combine a large proportion 93 percent by weight, 66 percent by volume of crushed quartz crystals with a binder of polyester resin.
