Most dust problems come from a few predictable errors. Fixing them is inexpensive compared with the cost of ill health, rework, and delays.

Mistake 1: Relying on free‑air figures

Specifying air scrubbers or extraction by free‑airflow overstates performance. Use airflow under load with filters and ducting fitted, and verify on site.

Mistake 2: Wrong filter class

M‑Class may be adequate for some wood and nuisance dusts, but respirable silica and carcinogens require H14. Mixing tasks without upgrading filtration leaves gaps.

Mistake 3: No source capture

Cleaning the air after the fact is harder. Fit shrouds, LEV, and water suppression so dust never escapes.

Mistake 4: Dry sweeping and compressed air

Both re‑suspend fine particles. Use industrial vacuums and damp methods instead, with regular filter checks.

Mistake 5: Poor zoning and pressure control

Open doors and shared routes spread dust to welfare, offices, and neighbours. Create dirty, buffer, and clean zones, and keep dirty spaces slightly negative.

Mistake 6: Neglecting maintenance

Loaded filters, worn seals, and split hoses destroy performance. Schedule inspections and keep spares on hand.

How to get it right

• Plan with the three‑layer framework: at source, in the air, on surfaces.
• Match filtration and airflow to the hazard, and record checks.
• Position equipment to move air from clean to dirty areas.
• Train teams to recognise and report dust escapes.

Where a range of tasks exists, a coherent equipment family can simplify training and spares; for example, the full MAXVAC range can support source capture, portable air filtration, and housekeeping without mixing unfamiliar interfaces.

Practical takeaways

• Specify under‑load airflow and H14 where required; verify on site.
• Stop dust at source first; never sweep or blow down.
• Zone, maintain slight negative pressure, and keep doors shut.
• Maintain filters, seals, and records; small defects cause big leaks.

Good dust control is disciplined, not complicated. Fix the common pitfalls and most of the problem disappears.
