HSE dust inspections focus on whether your controls actually protect people, not just what is written in a folder. Expect inspectors to look for clear evidence that dust is prevented at source, controlled in the air, and removed safely from surfaces, with records to prove this.

Core evidence inspectors expect to see

Risk assessment and method

• Task-specific COSHH assessments identifying dust types (e.g. RCS, wood dust) and exposure routes.
• Work plans showing how dust will be captured at source (on-tool extraction, water suppression) and controlled in the air (LEV, air scrubbers, negative air).
• Defined housekeeping methods that avoid dry sweeping and compressed air.

Controls in use and working

• On-tool extraction matched to the tool and material, with correct filter class (M for general mineral dust, H for fine/carcinogenic dusts such as silica).
• Evidence that airflow is sufficient under load, not just free-air figures. Simple checks include capture effectiveness at the point of work and pressure indicators where fitted.
• Containment where needed (enclosures, sheeting, pressure differentials) and make-up air routes to avoid leakage.

RPE and competence

• Appropriate RPE (e.g. P3) for the task, face-fit test records and user checks.
• Training records covering equipment set-up, filter changes, disposal and cleaning.

Maintenance and records

• LEV examinations where applicable, filter change logs and servicing schedules for vacuums and air scrubbers.
• Waste controls: sealed bagging, labelled storage and safe removal to prevent re-exposure.
• Housekeeping logs showing vacuum-based cleaning with high-efficiency filtration.

Compliance context (kept simple)

Under COSHH, you must reduce exposure so far as is reasonably practicable. For respirable crystalline silica, the HSE WEL is 0.1 mg/m³. Inspectors may ask how you know controls work, such as through observational checks, commissioning data, or periodic monitoring with a particulate meter.

Quick preparation checklist

• Confirm a source-control method for every dusty task before work starts.
• Verify filter classes and condition; have spare pre-filters on hand.
• Place air scrubbers to create directional airflow or negative pressure where needed.
• Brief the team daily on set-up, housekeeping and RPE use; record attendance.
• Use only industrial vacuums for clean-up; never dry sweep.
• Document inspections, defects and corrective actions the same day.

Well-run sites show control in practice: dust visibly captured at the point of work, clean air pathways, tidy housekeeping and up-to-date records. If you can demonstrate that, inspections tend to be straightforward.
