Dust Suppression Methods and Monitoring

TBT-ENV-045

Construction dust is a significant environmental nuisance that affects neighbouring residents, businesses, and the wider community. Excessive airborne dust can trigger enforcement action from local authorities under the Environmental Protection Act 1990. Effective dust suppression protects both public health and your site's licence to operate. This talk covers practical dust control methods and monitoring requirements.

Key Hazards
Respiratory health impacts on workers and neighbouring residents
Enforcement notices and site shutdown for excessive dust emissions
Reduced visibility on site and adjacent roads from dust clouds
Contamination of watercourses from uncontrolled dusty runoff
Control Measures
  • Damp down haul roads, stockpiles, and exposed ground during dry and windy conditions.
  • Use water bowsers or fixed sprinkler systems on large earthworks and demolition areas.
  • Erect solid hoarding around the site perimeter to contain dust within the boundary.
  • Cover loaded lorries with sheeting before they leave site to prevent dust dispersal on roads.
  • Locate dust-generating activities away from site boundaries and sensitive receptors where possible.
  • Install real-time dust monitors at site boundaries with alarm triggers for exceedance levels.
  • Record daily dust monitoring readings and respond to any elevated levels immediately.
  • Avoid dry sweeping; use vacuum sweepers or wet sweeping methods instead.
  • Brief all operatives on the dust management plan and their responsibilities.
Remember
  • Damp down all dusty areas during dry and windy conditions without exception
  • Cover all loaded lorries with sheeting before they leave the site
  • Monitor dust levels at site boundaries and respond to any exceedance alerts immediately
  • Never dry sweep; always use vacuum or wet sweeping methods on site
  • Dust complaints from neighbours can lead to enforcement action and site shutdown
  • Position dust-generating activities as far from sensitive receptors as possible
