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.
