Open sites face shifting winds, traffic, and large disturbed areas that promote dust drift. Complaints from neighbours, poor visibility, and health risks for workers follow when controls are reactive. A planned, weather-led approach prevents problems and keeps you aligned with HSE expectations.

Plan with the forecast and layout

Check wind and humidity daily. Position stockpiles and cutting stations downwind of sensitive boundaries. Create defined haul routes and keep clean zones upwind. Aim to disturb the smallest area possible at any time.

Suppress at source

• Water suppression on saws and breakers; use misting rather than jets to bind fine particles.
• Pre-wet haul roads and loading points; reapply during dry, windy spells.
• Reduce drop heights when tipping and loading; sheet lorries before moving off.
• Choose lower-dust methods (score-and-snap, bolt cutters) where feasible.

Contain and control movement

• Install windbreaks, debris netting, or hoarding along sensitive boundaries.
• Limit vehicle speeds and use wheel washing to prevent track-out.
• Segregate cutting, mixing, and crushing areas; keep them away from site exits.

Monitor and adapt

Use simple particulate monitors or visual inspections at boundaries to trigger actions. Record controls taken alongside weather conditions. Brief operatives daily on wind shifts and move high-dust tasks accordingly.

Practical takeaways

• Plan tasks around wind, humidity, and site layout.
• Use water suppression and minimise drop heights.
• Install barriers and control traffic speed/route.
• Prevent track-out with wheel wash and sheeting.
• Monitor and adjust in real time; document actions.

Consistent source suppression, boundary control, and simple monitoring prevent drift, protect neighbours, and support your COSHH risk management.
