Dust Suppression Methods

Construction dust is a nuisance to neighbours and a health hazard to workers — suppression is required on every active site.
The Greater London Authority and many local authorities require dust management plans under planning conditions.
Water sprays and misting systems are the most common dust suppression method, reducing airborne particles by up to 90%.
Damping down haul roads, stockpiles, and demolition areas with bowser trucks controls large-scale dust generation.
Wheel washing prevents vehicles carrying dust-laden mud onto public roads where it dries and becomes airborne.
Wind speed increases dust generation — exposed stockpiles and cleared areas must be covered or dampened in windy conditions.
On-tool water suppression for cutting and drilling controls dust at the point of generation before it becomes airborne.
Sheeting over skips, stockpiles, and loaded vehicles prevents wind carrying dust off site into neighbouring properties.
Continuous dust monitoring using real-time instruments helps identify when suppression measures need to be increased.
Community complaints about dust can trigger enforcement action, stop-work notices, and reputational damage for the project.

Worker health	Construction dust causes silicosis, asthma, and lung cancer — suppression protects workers from inhaling harmful particles.
Community impact	Dust from construction sites damages property, irritates residents, and triggers formal complaints and enforcement action.
Regulatory compliance	Planning conditions and environmental regulations require dust management plans — breaches lead to stop-work orders and fines.

Don't

Implement the site dust management plan and assign responsibility for dust control.
Use water sprays and bowsers to dampen haul roads, stockpiles, and work areas regularly.
Fit on-tool water suppression to all cutting and drilling equipment on site.
Cover skips, stockpiles, and loaded vehicles with sheeting to prevent wind-blown dust.
Use wheel wash facilities to remove mud from vehicles before they leave site.
Monitor wind conditions and increase suppression measures during windy weather.
Install real-time dust monitors at site boundaries to detect elevated dust levels.
Respond promptly to community complaints about dust with immediate suppression action.
Keep vegetation and ground cover in place as long as possible to reduce exposed soil.
Brief all workers on their responsibility to minimise dust from their activities.

DON'T ignore dust generation — it harms workers, neighbours, and the environment.
DON'T allow haul roads and stockpiles to dry out without regular damping down.
DON'T cut or drill concrete and stone without on-tool water suppression in place.
DON'T leave skips, stockpiles, or loaded lorries uncovered in windy conditions.
DON'T let vehicles leave site with muddy wheels that deposit dust on public roads.
DON'T continue normal operations during high winds without increasing dust controls.
DON'T ignore elevated readings on dust monitoring equipment — investigate and act.
DON'T dismiss community dust complaints — address them immediately and record the response.
DON'T strip vegetation and ground cover earlier than necessary for the work programme.
DON'T dry sweep exposed areas — use water or vacuum methods to control settled dust.
