Crystalline Silica and RSP Control Methods Effectiveness During Concrete Grinding
Concrete surface grinding exposes workers to unacceptable levels of airborne crystalline silica dust, known to cause diseases such as silicosis and lung cancer. The effectiveness of existing dust control methods and major confounding factors influencing the exposure levels of silica dust were examined by simulating field concrete surface grinding in an enclosed workplace laboratory. Personal, area, and background air monitoring was performed during 201 concrete grinding sessions ranging in duration from 5-90 minutes with approximately 80% grinding and 20% rest time per session. A variety of grinders, diamond grinding cups and accessories were used on concrete slabs, containing 24 9% crystalline silica, oriented in either horizontal or inclined positions. Dust control methods included general ventilation (GV), three types of local exhaust ventilation (LEV) and wet-grinding compared to conventional uncontrolled concrete grinding.
