Critical Engineering Controls for 2026

  1. Water Suppression Systems: Targeted sprays at dust generation points (drills, crushers, screens, conveyors)

    • Optimize droplet size for maximal capture—droplets must be large enough to intercept particles, but not so large as to cause over-wetting or slip hazards.
    • Use automated systems that synchronize with equipment activity to maximize efficiency and avoid water waste.
    • Avoid overuse (slip hazards, combustible dust, water management issues).
  2. Enclosures and Barriers:

    • Jacket conveyors, transfer chutes, and dust-prone areas to prevent fugitive dust escape.
    • Include easily accessible maintenance access panels (sealed when not in use), ensuring operational continuity and protection of critical zones.
  3. Ventilation Systems:

    • Local exhaust ventilation (LEV) at high emission hotspots.
    • Maintain negative pressure zones around dust-generating work areas.
    • High air changes per hour, optimized with real-time dust sensors.
  4. Dust Collectors and Filtration:

    • Deploy baghouse or cartridge filter systems at process equipment and transfer points.
    • Continually monitor pressure drop to ensure optimal filtration effectiveness and prevent system failures.
  5. Vehicle and Equipment Controls:
