Steps

  1. Maintain continuous inward airflow at all blast-cleaning enclosure openings during operation per 1910.94(a)
  2. Design and verify exhaust ventilation/dust collection consistent with the local exhaust system principles referenced in the standard
  3. Provide explosion venting/loose-panel construction on enclosures, ducts, and collectors where combustible dust may be present
  4. Supply respiratory protection under 1910.134 based on an exposure assessment, using abrasive-blast supplied-air respirators for silica-generating work
  5. Cross-check exposure controls against OSHA's separate respirable crystalline silica standard (1910.1053) whenever blasting generates silica dust
