SR 520 Bridge

Construction workers are engaged in activities that expose them to numerous health hazards, many of which cannot be seen. To further protect workers’ safety and health, NVL Laboratories’ industrial hygienists have provided on-call IH services over the duration of the SR 520 bridge construction process. Main responsibilities include preparation of a confined space work plan and worker exposure monitoring involving perimeter and clearance verification sampling for various airborne contaminants such as metals, volatile organic compounds, silica, and carbon monoxide. Total cost for the work performed was $280,000.
