Silica: A prevalent hazard on road construction sites

STAYING IN TOUCH: JACQUELYN ODURO

Silica is present in concrete, aggregate, and masonry products, the primary materials used in road construction. Silica is a health hazard and Workplace Safety and Health has been undertaking studies to demonstrate its effects on workers.

Silica exposure can lead to the development of silicosis, lung cancer and other chronic lung and breathing issues. To protect workers, remember:

• When possible, use water systems and ventilation to control dust, particularly in confined spaces
• Wear an appropriate respirator when working around silica dust
• Know and follow proper fitting, care and use procedures of respirators
• Thoroughly wash hands before eating or drinking in dusty areas
• Shower and change into clean clothes as soon as possible after work 

Control exposure to silica reaps benefits in the short and long term for workers. For resources regarding silica exposure and control, visit our website here or contact your regional safety advisor.
