Cleaning up wood dust safely

Cleanup is one of the dustiest jobs in the shop. Settled dust holds the fine particles that do the most harm to lungs, and the wrong cleaning method puts them straight back into the air you breathe.¹²

Never dry sweep or blow dust off

• No brooms or dry brushing. Sweeping lifts fine dust into the air.¹
• No compressed air. Blowing dust off benches, machines, furniture or clothing creates a dust cloud and spreads the dust around the shop.³ HSE lists both dry sweeping and compressed air among the causes of high dust exposure.³
• What about OSHA’s 30 psi rule? US rules allow compressed air for cleaning only below 30 psi and with chip guarding and protective equipment.⁴ That rule is about injuries from the air jet and flying chips. It does not make blowing dust safe to breathe.
• Never blow dust off yourself. Use a vacuum or change clothes instead.³

Use a vacuum made for fine dust

• HSE recommends a vacuum that meets at least dust class M (medium hazard), or a suction hose connected to your extraction system.³ If your vacuum doesn’t carry a dust class, look for a stated high-efficiency filter for fine dust.
• HSE’s fire guidance also recommends vacuums with HEPA-type filters for regular cleaning to stop dust building up.⁵
• Check what any vacuum’s filter is rated to catch before trusting it with fine sanding dust.
• Empty the vacuum carefully while wearing your respirator. Emptying dust bags is a high-exposure job.³

Damp wipe what the vacuum can’t reach

Wipe ledges, shelves and tool tops with a damp cloth. Fine dust spreads well beyond the machine, so clean ledges and other surfaces regularly before it builds up.³ Rinse the cloth often. For floors, vacuum first, then damp mop if needed.

Wear your respirator for cleanup

Cleaning and maintenance can produce high dust levels even when the tools are off, and HSE expects a respirator for these short jobs.³ Keep it on until the air has settled and the vacuum is put away.

Clean little and often

• Cleaning at the end of each session stops dust from piling up.
• Dust left on beams, light fittings and ductwork is also a fire and explosion hazard. A first explosion can shake it loose and ignite it.⁵ See Fire and explosion.

Don’t take dust home

Dust travels on clothes, shoes, skin and hair to floors, furniture and car seats, where family members and pets can come in contact with it.⁶ NIOSH’s advice on take-home exposures applies well to wood dust:⁶

• Wear shop clothes or a shop coat that stays in the shop.
• Change clothes and shoes before going indoors, or take shoes off at the door.
• Keep dusty clothes apart from clean ones and wash them separately.
• Wash your hands, and shower if you’ve had a very dusty day.

Store your respirator and other protective gear where it won’t get dusty between uses.⁷

Checklist

• Class M (or HEPA-type) vacuum, or a hose on the extraction system.
• No broom, no compressed air, not even on clothes.
• Damp wipe ledges and tool tops.
• Respirator on during cleanup and emptying.
• Shop clothes stay in the shop; wash separately.
