Effective dust management doesn't rely on a single control method. It uses a layered approach that combines prevention, capture, and housekeeping to form a complete system of protection. This model aligns with established safety hierarchies and ensures compliance while maintaining productivity.

Layer 1: Prevention – Stopping Dust at Source

The most effective way to reduce dust exposure is to prevent it from being generated. Water suppression during cutting, tool extraction attachments, and process redesign all fall under this principle. Simple steps like slower cutting speeds or using pre-mixed materials can significantly reduce airborne dust formation.

Layer 2: Capture – Controlling Emissions During Work

Where prevention is not feasible, capture and containment take over. Local exhaust ventilation, on-tool extraction, and enclosed work zones all aim to remove dust from the air before it reaches breathing zones. The type and efficiency of vacuum used have a major impact here. Using the correct filter class and maintaining system pressure ensures the extraction stays effective throughout the job.

Layer 3: Housekeeping – Cleaning and Maintenance

The third layer focuses on cleaning settled dust and maintaining equipment. Dry sweeping and compressed air should be avoided as they resuspend fine particles. Instead, use vacuums with appropriate filtration and rugged construction for industrial conditions. Regular servicing of filters prevents blockages that can reduce efficiency or release dust back into the environment.

Integrating Layers into a Single Plan

These layers are most powerful when combined in a single dust management plan. Site assessments identify which processes produce dust and help prioritise investment. Training workers in proper equipment use, filter maintenance, and waste disposal ensures the system works as intended. Documentation demonstrates compliance with COSHH or equivalent standards.

Practical Takeaways

• Always aim to prevent dust before relying on capture or clean-up
• Keep extraction systems maintained and filters replaced on schedule
• Avoid sweeping or blowing methods that create airborne dust
• Provide worker training and record keeping to demonstrate compliance
• Review your dust plan after process or equipment changes

When planned and managed cohesively, these three layers protect workers and equipment while improving air quality and productivity.
