Woodworking produces fine and coarse dust that settles on surfaces and lingers in the air. Without adequate control, this dust can threaten workers' health, compromise the finish of products and increase fire risk. In joinery and carpentry, where saws, planers and sanders are constantly in use, managing dust is both a legal duty and a quality priority.

Why Wood Dust Matters

Hardwood dusts are classified as carcinogenic by health authorities, with prolonged exposure linked to nasal cancer and respiratory issues. Even softwood dust presents irritation risks. For workshops operating under the Control of Substances Hazardous to Health (COSHH) Regulations, maintaining exposure below workplace limits is mandatory. Beyond regulatory pressure, clean air supports efficient operation and cleaner product finishes.

Source Capture and Extraction

The most effective control method is source extraction. Each woodworking machine should be connected to a correctly sized LEV system using smooth ducting and minimal bends. High‑efficiency dust extractors capture chips and fine dust as they are generated, preventing them from spreading through the workshop. Filters must achieve at least M‑class performance to protect health. Routine testing under HSG258 guidance verifies that airflow and capture velocities remain sufficient.

Housekeeping and Secondary Controls

Even with effective LEV, some dust will settle on floors and surfaces. Dry sweeping should be avoided as it can reintroduce fine particles into the air. Industrial vacuums with HEPA filtration or wet methods are safer. Regular cleaning schedules should be documented, and bins emptied before overfill restricts airflow. Storage areas and finishing rooms often get overlooked; ensure extraction reaches those zones too.

Maintenance and Record Keeping

LEV systems must be examined at least every 14 months by a competent person. Records should be retained for inspection. Filters and collection bags should be monitored for wear and tear to prevent performance loss. Airflow gauges provide instant verification that systems are operating within specification, helping avoid unnoticed failures.

Practical Takeaways

• Install LEV on every dust-generating machine.
• Use M‑class or higher rated filters.
• Clean with vacuum methods, never dry sweep.
• Keep maintenance logs up to date.
• Train workers in the correct use of extraction equipment.

Good dust management in joinery and carpentry goes beyond cleanliness. It ensures compliance, protects craftsmen and preserves the precision of finished work. Regular inspection and correct equipment selection make a measurable difference to both safety and quality.
