Good dust control shortens programmes, reduces stoppages, and keeps quality high. Time lost to cleaning, rework, and poor visibility often outweighs the cost of controls. Treat dust as a production risk and plan it alongside labour, access, and logistics.

Plan methods that minimise dust

Choose lower‑dust processes where possible: pre‑cut off site, use water suppression for masonry, and fit on‑tool extraction matched to the material. Build dust control into method statements and RAMS so trades arrive with the right attachments, filters, and waste plan. Modular systems can be redeployed between zones to track the critical path.

Use the three‑layer approach

1) Capture at source

Slow cutting speeds, sharp blades, and correct shrouds reduce escape. For timber and board, M‑Class extraction is the baseline; for RCS and carcinogenic dusts, plan for H‑Class and H14 filtration in downstream air units.

2) Capture in the air

Position air scrubbers to pull air across the workface and out of the breathing zone. Aim for steady airflow under load, not free‑air figures, and use temporary barriers to guide flow. Negative air helps during strip‑out and grinding.

3) Capture on surfaces

Avoid sweeping and compressed air. Use industrial extractors with high‑efficiency filters and bagged disposal. Short, frequent point‑of‑task cleans prevent build‑up that triggers later stoppages.

Make it measurable

Use a simple particulate monitor to check peaks during cutting or breaking. If levels spike, tighten source capture, add another air scrubber, or slow the process. Keep a quick log so teams see which controls save time.

Practical takeaways

• Write dust controls into RAMS and pre‑start briefings.
• Set one accountable person per zone to maintain extraction and filters.
• Place air scrubbers to create flow across work, not just mix air.
• Swap sweeping for extractor‑based housekeeping in short cycles.
• Track downtime; reinvest saved minutes in better control where peaks persist.

Done well, dust control becomes a productivity tool: clearer lines, fewer callbacks, and faster handovers with less disruption to adjacent trades.
