Dust

Multistage Filtration System (MSFS)

Multistage Filtration Systems (MSFS) are used to reduce employee exposure to airborne dust by filtering and cleaning contaminated air in high-dust environments. This leading practice focuses on applying layered filtration to remove dust particles more effectively, improving air quality and supporting compliance with occupational exposure limits.

In mining environments where dust is generated continuously, filtration systems form an important part of an integrated dust management strategy. A multistage approach uses more than one filtration layer or mechanism, allowing the system to capture larger particles first and progressively filter finer, respirable dust fractions in later stages.

Key benefits

  • Improved removal of airborne dust through staged filtration
  • Reduced employee exposure in high-dust work areas
  • Enhanced air quality where engineering controls are required
  • Supports progress toward dust milestones and Zero Harm objectives

MSFS installations are typically applied in areas where airborne dust accumulates, or where dust-generating activities create persistent exposure risks. When combined with effective ventilation, housekeeping and source control measures, filtration contributes to sustained dust reduction outcomes.
