In-Depth Survey Report: Engineering Control of Silica Dust from Stone Countertop Fabrication and Installation. The results from the task-based samples in this survey revealed that wet grinding and wet polishing both granite and engineered quartz stone may still lead to overexposure to respirable crystalline silica.

The Facts About Silica According to the National Institute for Occupational Safety and Health (NIOSH), inhaling respirable crystalline silica can cause silicosis, a debilitating and potentially fatal lung disease. Silica exposure has also been associated with lung cancer, chronic obstructive pulmonary disease (COPD), and renal disease

Silica dust or respirable crystalline silica (RCS) is generated in workplace mechanical processes such as crushing, cutting, drilling, grinding, sawing or polishing of natural stone or man-made products that contain silica. RCS can penetrate deep into the lungs and can cause irreversible lung damage.

To best understand silica, we must address where it comes from and how it is formed. Silica makes up most of the Earth's crust. 100 times smaller than sand, silica is not visible to the naked eye. Today silica is found in many building materials, with dust forming by cutting, grinding, or drilling these materials on the construction site.
