Personal and environmental sampling of a foundry (SIC-3339) reveals that employees performing sand mulling, pouring and shakeout operations are exposed to potentially toxic concentrations of crystalline silica (quartz) (1317799) which can cause silicosis. In addition, excessive noise levels are noted and excessive levels of methane (74828) present an explosive gas hazard. Recommendations are presented for the control of silica (7631869) dust, including maintenance of ventilation systems, local exhaust ventilation, and use of respiratory protective equipment.
