Around 2.1 million GB workers are exposed to wood dust, a Group 1 carcinogen. The key UK wood dust exposure, cancer and HSE enforcement statistics for 2026.
Wood dust looks harmless — a nuisance to sweep up rather than a substance to fear — but it is one of the very few workplace agents the International Agency for Research on Cancer (IARC) places in Group 1, the same confirmed-carcinogen category as asbestos and respirable crystalline silica. This page gathers the key UK statistics in one place: how many workers are exposed, how strongly wood dust is linked to nasal cancer, what the workplace exposure limit is, and what the Health and Safety Executive’s (HSE) recurring “Dust Kills” woodworking inspections keep finding. The figures are drawn from HSE guidance and enforcement data, HSE’s burden-of-occupational-cancer research, the IARC monographs, the Industrial Injuries Advisory Council (IIAC) and peer-reviewed meta-analyses.
Key facts and figures
- 2.1 million GB workers are estimated to be exposed to wood dust at work — 1,744,690 men and 404,352 women.
- Group 1 — IARC classifies wood dust as a confirmed human carcinogen, causally linked to cancer of the nasal cavity and paranasal sinuses.
- 5.91 is the pooled relative risk of sinonasal cancer from wood dust exposure in case-control studies (95% CI 4.31–8.11).
- 29.43 is the pooled relative risk for the adenocarcinoma subtype specifically (95% CI 16.46–52.61) — among the strongest occupational cancer associations known.
- 3 mg/m³ is the UK workplace exposure limit for hardwood dust (8-hour TWA); softwood dust is 5 mg/m³.
- 78% of 1,000+ woodworking firms inspected in HSE’s 2022–23 Dust Kills wave were failing to control respiratory sensitisers — nearly 8 in 10.
- 402 enforcement actions were taken by HSE inspectors during that Dust Kills woodworking wave.
- 4× — carpenters and joiners are four times more likely to develop asthma than other UK workers.
Figures are the latest available as of July 2026; this page is updated when new data is released — HSE publishes its annual work-related asthma and lung disease statistics each autumn, and issues fresh inspection tallies after each Dust Kills woodworking or construction campaign.
How many people are exposed to wood dust at work in the UK?
Around 2.1 million GB workers — 2,149,042, made up of 1,744,690 men and 404,352 women — are estimated to be exposed to wood dust at work, according to the exposure figures underpinning HSE’s burden-of-occupational-cancer research (base year 2005, published 2012). That makes wood dust one of the most widespread carcinogenic exposures in the British workforce, ahead of many substances that attract far more attention.
Exposure is concentrated in a recognisable set of trades: joinery, furniture and cabinet making, sawmilling and timber processing, construction carpentry, shopfitting, and any workshop where wood is sawn, sanded, routed, turned or planed. As with silica, the hazard is generated by the work itself rather than bought in a labelled container, which is exactly why it is so easily missed in a COSHH risk assessment — there is no supplier warning on a plank of oak. Wood dust is nonetheless firmly a substance covered by COSHH, and one HSE inspectors ask about routinely in workshops.
Can wood dust cause cancer — is it a carcinogen?
Yes. IARC classifies wood dust as a Group 1 (confirmed human) carcinogen, causally linked to cancer of the nasal cavity and paranasal sinuses, in Monograph Volume 100C (2012). Group 1 is the highest certainty category in the IARC scheme — the classification reflects consistent human evidence, not animal studies alone.
The strength of that link is unusually large. A 2015 systematic review and meta-analysis in BMC Cancer (Binazzi and colleagues) put the pooled relative risk of sinonasal cancer from wood dust exposure at 5.91 (95% CI 4.31–8.11) across case-control studies, and 1.61 (95% CI 1.10–2.37) across cohort studies. The association is far stronger for one specific tumour type: for sinonasal adenocarcinoma, the pooled relative risk reaches 29.43 (95% CI 16.46–52.61). An earlier pooled reanalysis of 12 case-control studies (Demers and colleagues, cited in HSE’s evidence base) found an adenocarcinoma odds ratio of 13.5 (95% CI 9.0–20.0) for wood-related occupations, rising to 45.5 (95% CI 28.3–72.9) in the highest-exposure jobs. Relative risks of that magnitude are among the strongest ever recorded for any occupational carcinogen.
Occupation-level data tells the same story. HSE’s burden research reports a sinonasal-cancer standardised mortality ratio (SMR) of 4.3 (95% CI 2.2–7.8) among furniture workers, rising to 8.4 (95% CI 3.9–16.0) among those with definite wood-dust exposure. In plain terms, a furniture worker with confirmed exposure is several times more likely to die of nasal cancer than the general population.
How much nasal cancer does wood dust cause in Britain?
About 10% of sinonasal cancer in Great Britain is attributable to occupational wood dust — 10.02% (95% CI 3.85–19.60%) in HSE’s occupational-cancer burden estimates — giving roughly 11 deaths (95% CI 4–22) and 39 cancer registrations (95% CI 15–76) a year. Wood dust is also linked to nasopharyngeal cancer, with an attributable fraction of 7.62% (95% CI 1.08–17.98%), giving around 7 deaths and 14 registrations a year (HSE burden research, 2005 base year).
Those wood-dust-specific figures sit inside a larger occupational picture. Across all occupational exposures combined, sinonasal cancer carries an attributable fraction of 32.67% — about 38 deaths and 126 registrations a year in GB — meaning roughly a third of all nasal cancers in Britain trace back to work, with wood dust the single largest identified contributor. The table below summarises the wood-dust cancer burden.
| Cancer site | Attributable fraction (wood dust) | Deaths / registrations a year (GB) |
|---|---|---|
| Sinonasal cancer — wood dust alone | 10.02% (95% CI 3.85–19.60%) | ~11 deaths / ~39 registrations |
| Nasopharyngeal cancer — wood dust alone | 7.62% (95% CI 1.08–17.98%) | ~7 deaths / ~14 registrations |
| Sinonasal cancer — all occupational causes | 32.67% | ~38 deaths / ~126 registrations |
| Furniture-worker sinonasal SMR (definite exposure) | 8.4 (95% CI 3.9–16.0) | Standardised mortality ratio |
All of these figures rest on HSE’s 2005 base-year burden research, which remains the current published estimate. As with silica, death and registration counts in the low dozens sit alongside a much wider exposed population, because nasal cancer from wood dust typically appears decades after the exposure that caused it.
Is wood-dust nasal cancer a recognised industrial disease?
Yes. Carcinoma of the nasal cavity and associated air sinuses caused by wood dust is a prescribed industrial disease (PD D6) for Industrial Injuries Disablement Benefit, following the advice of the Industrial Injuries Advisory Council (IIAC). Prescription means a worker who develops the disease after qualifying woodworking employment can claim benefit without having to prove their individual case — the occupational link is accepted in law.
The historical evidence behind that recognition is stark. In the case series the IIAC reviewed, roughly 1 in 4 nasal adenocarcinomas — 24 of 108 — occurred in furniture-industry workers, a concentration far beyond what chance would produce in the general population. That clustering, first noticed in the English furniture-making town of High Wycombe decades ago, is a large part of why wood dust is treated as seriously as it is today.
What are the respiratory effects of wood dust?
Cancer is the distinctive endpoint, but the more common day-to-day harm is respiratory. Carpenters and joiners are four times more likely to develop asthma than other UK workers, according to HSE’s woodworking guidance, and wood dust is consistently one of the leading identified causes of occupational asthma reported through the THOR surveillance network. Wood dust is a respiratory sensitiser: once a worker becomes sensitised, even low exposures can trigger an asthmatic reaction, and the effect can be permanent.
Occupational asthma as a disease in its own right — its overall UK case numbers, causes and trends — is covered on our dedicated occupational asthma statistics page; here it appears only as one of wood dust’s health endpoints. Because wood dust causes asthma, COSHH requires exposure to be reduced as low as reasonably practicable rather than merely kept below the exposure limit — the same heightened standard applied to carcinogens, worked through the COSHH hierarchy of control.
What is the workplace exposure limit (WEL) for wood dust in the UK?
3 mg/m³, averaged over an 8-hour working day, is the UK workplace exposure limit (WEL) for hardwood dust; for softwood dust it is 5 mg/m³ (8-hour TWA), as set out in HSE’s woodworking guidance under the COSHH Regulations 2002. Where hardwood and softwood dusts are mixed — as they routinely are in a general joinery workshop — the stricter 3 mg/m³ hardwood limit applies to the whole mixture.
The limit is a ceiling, not a target. Because hardwood dust is a carcinogen and wood dust is a respiratory sensitiser, COSHH requires exposure to be reduced as far below the WEL as is reasonably practicable. In practice that means on-tool or fixed local exhaust ventilation (LEV) at every dust-generating machine, no dry sweeping, and tight-fitting respiratory protective equipment (RPE) with face-fit testing as a supplement rather than a substitute for extraction.
What did HSE’s Dust Kills woodworking inspections find?
Nearly 8 in 10 woodworking firms fell short. In HSE’s 2022–23 Dust Kills inspection wave, inspectors visited more than 1,000 woodworking businesses and found 78% failing to adequately protect workers from respiratory sensitisers such as wood dust, taking 402 enforcement actions as a result. Dust Kills is a recurring HSE campaign that periodically targets woodworking and construction, so fresh inspection tallies follow each new wave.
Detailed occupational-hygiene fieldwork paints a similar picture of under-control. In HSE site visits to woodworking manufacturers reported in Annals of Work Exposures and Health (2024, fieldwork 2014–17), 17.6% of hardwood or mixed-dust exposures exceeded the 3 mg/m³ hardwood WEL and 6.0% exceeded even the 5 mg/m³ softwood limit. Yet at those same sites, only 32% (7 of 22) had face-fit-tested tight-fitting RPE and 59% (13 of 22) carried out respiratory health surveillance — despite 95% (21 of 22) having LEV under thorough examination and test. In other words, most workshops had bought the extraction equipment but had not closed the loop on the human controls that make it effective.
The wider human cost frames why HSE keeps knocking on woodworking doors: it estimates around 12,000 deaths a year in GB from lung diseases linked to past workplace exposures, and about 19,000 new cases a year of breathing or lung problems caused or made worse by work (HSE, cited in the Dust Kills campaign).
How should a workshop control wood dust?
The practical starting point is the same as for any hazardous substance: a suitable and sufficient COSHH risk assessment covering the dust the work creates, not just the timber bought in. From there the hierarchy of control sets the order — reduce dust at source with well-designed LEV on every machine and on portable tools, keep the workshop clean by vacuum or wet methods rather than dry sweeping or compressed air, supplement with face-fit-tested FFP3 RPE where residual exposure remains, and run health surveillance so early asthma or nasal symptoms are caught before they become disease.
Training underpins all of it. Workers who understand that wood dust is a Group 1 carcinogen and a respiratory sensitiser — not just sawdust to be brushed away — use extraction and RPE differently. That understanding is exactly what the Regulation 12 information, instruction and training duty exists to deliver, and one of the topics covered in structured COSHH Training. For construction dusts specifically, respirable crystalline silica from cutting stone, concrete and brick is a separate hazard with its own limit — see our silica dust statistics for that.
Frequently asked questions
How many people are exposed to wood dust at work in the UK?
Around 2.1 million GB workers — about 2,149,042, made up of 1,744,690 men and 404,352 women — are estimated to be exposed to wood dust at work, according to the exposure data behind HSE’s occupational-cancer burden research. That makes it one of the most widespread carcinogenic exposures in the British workforce.
Can wood dust cause cancer — is it a carcinogen?
Yes. IARC classifies wood dust as a Group 1 (confirmed human) carcinogen, causally linked to cancer of the nasal cavity and paranasal sinuses. The pooled relative risk of sinonasal cancer is 5.91 in case-control studies, rising to 29.43 for the adenocarcinoma subtype — among the strongest occupational cancer associations recorded.
What is the workplace exposure limit (WEL) for wood dust in the UK?
The WEL for hardwood dust is 3 mg/m³ over an 8-hour working day, and 5 mg/m³ for softwood dust. Where hardwood and softwood dusts are mixed, the stricter 3 mg/m³ hardwood limit applies to the whole mixture. Because hardwood dust is a carcinogen, exposure must be reduced as far below the limit as is reasonably practicable.
What did HSE’s Dust Kills woodworking inspections find?
In HSE’s 2022–23 Dust Kills wave, inspectors visited more than 1,000 woodworking businesses and found 78% — nearly 8 in 10 — failing to adequately protect workers from respiratory sensitisers such as wood dust, taking 402 enforcement actions.
Is wood-dust nasal cancer a recognised industrial disease?
Yes. Carcinoma of the nasal cavity and associated air sinuses from wood dust is a prescribed industrial disease (PD D6) for Industrial Injuries Disablement Benefit. In the historical case series behind that recognition, roughly 1 in 4 nasal adenocarcinomas — 24 of 108 — occurred in furniture-industry workers.
Are carpenters more likely to get asthma?
Yes. HSE reports that carpenters and joiners are four times more likely to develop asthma than other UK workers, because wood dust is a respiratory sensitiser. Once a worker is sensitised, even low exposures can trigger a reaction, which is why exposure must be minimised rather than simply kept below the limit.
