Silica Hazards in Granite

Silicosis is an irreversible and progressive lung disease that can cause serious disability or death. This disease is caused by a naturally occurring mineral known as crystalline silica. It is a basic component of sand, quartz and granite rock. Employers should first conduct air monitoring to obtain baseline levels of airborne crystalline silica dust. Per Cal/OSHA, air monitoring of silica dust in the granite counter top fabrication industry has shown to reach and exceed permissible exposure levels.
