Protecting yourself from wood dust

All wood dust is hazardous (why), but most of the risk can be controlled with a few habits. The order you tackle them in matters.

Start at the top: the hierarchy of controls

Safety agencies rank protective measures from most to least effective. This is the hierarchy of controls.¹

1. Remove or reduce the dust at its source. Choose a less dusty process where you can, such as a sharp hand plane or scraper instead of sanding, which makes the finest dust.²
2. Capture it at the tool. Extraction at the point where dust is made is the main control. It protects everyone in the room, not just you.³
3. Change how you work. Cut down how long and how often you do dusty jobs, keep others away, and clean up safely.¹
4. Wear protection. A respirator, eye protection and suitable clothing come last because they only protect the wearer and only work when worn correctly.³¹

Most shops need all four. HSE expects that sawing, routing and sanding will usually still need a respirator even with good extraction.³

Why the order matters

• Engineering controls such as extraction work without relying on people remembering to do something.¹
• Respirators fail quietly: a poor fit, a beard or a clogged filter lets dust in without you noticing.³
• For dusts that cause asthma or cancer, the goal is not just to stay under a limit. It is to keep exposure as low as is reasonably practicable.²

The checklist

Use this as a quick check before a dusty job. A printable version is available.

At the source

• Every machine that makes dust is connected to extraction, and the extraction is on.
• Sanders are connected to an extractor or vacuum. On-tool extraction can cut sander dust emissions a lot; one NIOSH design cut them by about 90%.⁴
• Blast gates and hoods are set for the tool you’re using.³

In the air

• Filters on collectors and vacuums are clean and in good condition.³
• Fine dust is checked from time to time, for example with a bright light shone across the work area.³

On you

• A respirator rated for fine dust, fitted to your face, not a nuisance dust mask.³
• Clean-shaven where the mask seals, or a loose-fitting powered respirator.⁵⁶
• Safety glasses or goggles.⁷
• Long sleeves or a shop coat that stays in the shop.⁸

Afterwards

• Clean with a dust-rated vacuum, never a broom or compressed air.⁵
• Change out of dusty clothes and wash your hands before going indoors.⁸
• Rags used with oil finishes are dealt with safely (fire risks).

The detail pages

• Dust collection: extraction at the tool, collectors and vacuums, and why sanding is the worst offender.
• Respirators: dust masks vs N95 vs P100 vs powered respirators, fit and filters.
• Skin and eyes: gloves, clothing, washing and eye protection.
• Cleanup: vacuums and damp wiping, and not taking dust home.
• Fire and explosion: combustible dust, collector fires and oily rags.

Hobby shops and workplaces

Workplace rules apply to employers, but the hazards are the same in a garage. If you use a respirator voluntarily at home, the same basics apply: use a certified respirator, follow the maker’s instructions, and use it only against the hazard it is designed for.⁹ In UK workplaces, employers are expected to control wood dust with extraction, respirators and health checks.¹⁰

If you notice symptoms

A runny nose, cough or wheeze that eases on days away from the shop can be an early sign of a wood dust allergy.¹¹ See Symptoms and talk to a doctor.
