Engineering Controls

  1. Substitution
    • Use a less toxic abrasive blasting material.
    • Use abrasives that can be delivered with water (slurry) to reduce dust.
  2. Isolation and Containment
    • Use barriers and curtain walls to isolate the blasting operation from other workers.
    • Use blast rooms or blast cabinets for smaller operations.
    • Use restricted areas for non-enclosed blasting operations.
    • Keep coworkers away from the blaster.
  3. Ventilation
    • Use exhaust ventilation systems in containment structures to capture dust.
