Evaluation of Crystalline Silica Exposure during

2002]. Granite has been reported to contain between 2% and 60% quartz, a type of crystalline silica, by volume [Phillips et al. 2013]. In contrast, engineered stone can contain a higher percentage of quartz; it can potentially contain over 90% crystalline silica [OSHA 2015a].

Severe Silicosis in Engineered Stone Fabrication Workers

Sep 26, 2019 Engineered stone contains substantially more silica than does natural stone (>90%, compared with <45% in granite) (6), exposing workers to higher amounts of silica dust. In recent years, engineered stone countertops have become increasingly popular; quartz surface imports to the United States increased approximately 800% during 2010–2018. ¶
