Effective containment protects people, keeps neighbours on side and reduces rework. This guide focuses on building and running systems that actually control dust during renovation and fit-out.
Plan the zone
- Define dirty, transition and clean areas; agree access routes and waste paths.
- Choose a pressure strategy: usually slight negative pressure within the work zone.
- Map air from clean to dirty to extract; provide make-up air to avoid collapse of barriers.
Build barriers that seal
- Use rigid panels or reinforced sheeting for longer jobs; brace frames securely.
- Seal edges to floors, walls and soffits. Close penetrations with tape, sleeves or box-outs.
- Install doors that self-close; add tack mats at exits.
Control the air
- Extract from the dustiest point; duct outside if possible, otherwise use recirculating HEPA units.
- Select equipment by under-load airflow, not free-air numbers, and allow for filter loading.
- Use H14 filtration for fine or carcinogenic dusts (e.g., RCS). An H-class air scrubber such as a MAXVAC Dustblocker can provide continuous air cleaning.
- Verify negative pressure with a simple manometer or tissue test, and spot-check with a particulate meter.
Operate and maintain
- Entry protocol: close doors, no dry sweeping, bag waste inside the zone.
- Housekeeping: top-down vacuuming with an H-class industrial vacuum; wipe touch points.
- Maintenance: check filters, seals and ducts daily; log changes and alarms.
Three-layer control in practice
- Capture at source: LEV, shrouds, water suppression, process changes.
- Capture in the air: air scrubbers and negative air units sized for the space.
- Capture on surfaces: avoid re-agitation through proper vacuuming and scheduled cleaning.
Practical takeaways
- Plan airflow from clean to dirty and provide make-up air.
- Seal thoroughly and check pressure direction daily.
- Choose equipment on under-load performance and H14 filtration where required.
- Run a simple log for filters, alarms and cleaning to keep the system effective.
Well-planned containment limits spread, reduces neighbour complaints and shortens final clean. The payoff is safer work and smoother handovers.
