Common Jobsite Tasks That Generate Silica Dust

June 27, 2025

Some of the most routine construction tasks can quietly release hazardous silica dust into the air—often without anyone realizing the long-term risk.

Why It Matters:

When silica dust is airborne and inhaled, it can cause irreversible lung damage. Identifying which tasks release silica helps teams implement the right controls before exposure happens.

Key Points:

  • Cutting, grinding, or drilling concrete, brick, tile, or stone generates high levels of silica dust.
  • Using handheld saws, chipping tools, or jackhammers during demolition also contributes to airborne silica.
  • Mixing dry concrete or mortar can release dust if done without precautions.
  • Sweeping or using compressed air to clean dusty surfaces stirs up settled silica and creates inhalation risks.
  • Masonry, tunneling, and excavation may disturb materials with natural crystalline silica content.
  • Workers near these operations—even if not directly performing the task—are also at risk from drift or accumulation.

✅ Know the tasks. Control the dust. Protect your lungs.

Ask the Crew:

  • What silica-generating tasks are happening today?
  • Are we using dust controls and PPE properly?
  • Could anyone nearby be affected by our work?
