Extraction comes before RPE. The fastest route to lower exposures, better visibility, and fewer clean-ups is to stop dust at source, control what escapes, and use RPE as the final safeguard.

Start with prevention

• Plan the task: choose methods that generate less dust, pre-fabricate where possible, and use water suppression.
• Fit tool-mounted extraction sized for the tool and material; verify airflow under load.
• Position the cut to direct dust into the hood rather than across the operator.

Control what becomes airborne

• Use air scrubbers or negative air to create a consistent pull away from breathing zones.
• Select high-efficiency filtration (H14 for fine/carcinogenic dusts) and service filters before they load up.
• Zoning and simple sheeting reduce spread into clean areas.

In enclosed areas, a compact MAXVAC air scrubber can help stabilise background levels while you tune source extraction.

Keep surfaces from re-feeding the air

• Vacuum, don’t sweep. Schedule clean-downs during the shift, not just at the end.
• Use sealed-bag vacuums to prevent leakage when emptying.

Where RPE fits

• Provide RPE (e.g., P3) for set-up, short high-dust tasks, or while verifying controls.
• Face-fit test, train wearers, and maintain spares and filters.

Practical takeaways

• Lead with at-source extraction; air cleaning and housekeeping support it.
• Use RPE as a safety net, not the primary control.
• Measure outcomes with a particulate monitor and adjust layout and kit.

Put engineering controls first and RPE last to align with COSHH and to achieve real, repeatable reductions in dust exposure.
