How to Estimate Silica Exposure on a Construction Site

1. Select silica-generating tasks: Choose from 12 common construction tasks like concrete cutting, grinding, tuck-pointing, and jackhammering.
2. Set duration for each task: Enter the number of hours per day each task is performed (0.5 to 8 hours).
3. Review exposure estimates: See uncontrolled and Table 1 controlled 8-hour TWA estimates compared to the 50 µg/m³ PEL.
4. Check triggered requirements: View which OSHA requirements are triggered: exposure monitoring, medical surveillance, written plan, and training.
