Occupational Cancers in Construction: The Risks Nobody Mentions

‍‌‌​‌​​‌‌‌​​​‌‌​​‌​​‌‌​​‌​‌‌​‌‌​‍# Occupational cancers in construction, what you should know

Occupational cancer is the slowest-moving car crash in construction, asbestos, silica, diesel and sun don't hit you tomorrow, they hit you 20–40 years down the line. The good news is you can cut your risk a lot, and you can protect your future self by recording what you're exposed to now.

Quick rule of thumb: in construction, occupational cancer kills far more people than accidents: most of them from exposures that felt "normal" at the time. You don't need to turn into a safety officer, but you do need to take the invisible stuff seriously.

1. How big the problem really is

• HSE says construction has the largest burden of occupational cancer of any UK industry: over 5,000 new cases and about 3,700 deaths a year from past exposures.
• Around 70% of those cases are down to asbestos, about 17% to silica, and 6–7% each to diesel exhaust and work as a painter.
• Solar UV and coal-tar products add another 1,300 non-melanoma skin cancers a year in construction.

So when people say "it's the dust and the fumes that kill you later", that's not scaremongering, it's straight HSE data.

2. The main cancers and what causes them on site

Mesothelioma and asbestos-related lung cancer

• Asbestos is still the biggest occupational disease risk to construction workers.
• HSE estimates asbestos was responsible for the death of over 2,500 construction workers in 2005 alone, more than two-thirds of cancer deaths in the industry that year.
• Mesothelioma is a cancer of the lung lining, almost always caused by asbestos. It's always fatal.
• Latency: it typically develops 30–40+ years after exposure; most deaths are in people over 75, from exposures in the 1970s–1990s.
• Big exposure risks now are on domestic and small refurbs · drilling, chasing, removing old artex, lagging, boards and tiles without proper surveys or controls.

Lung cancer, silica, diesel, welding and asbestos

• Silica dust: RCS is "the biggest risk to construction workers after asbestos": heavy, long-term exposure can cause lung cancer as well as silicosis. HSE estimates silica exposure caused over 500 construction worker deaths in 2005.
• Diesel exhaust: the IARC (global cancer body) classifies diesel engine exhaust as Group 1: known human carcinogen for lung cancer. Construction plant, generators and site vehicles are a major source.
• Welding fumes: classed as carcinogenic; regular welding/smoke exposure without fume extraction and RPE increases lung-cancer risk.
• Asbestos-related lung cancer: asbestos doesn't just cause mesothelioma; it also causes standard lung cancer, especially if you smoke as well.

Skin cancer, outdoor work and UV

• Long-term outdoor work without sun protection leads to non-melanoma and melanoma skin cancer, especially on face, ears, neck and arms.
• IOSH's "No Time to Lose" campaign flags solar UV as one of the top occupational carcinogens, alongside asbestos, diesel and silica.

Bladder cancer and others

• Bladder cancer risk is increased by long-term exposure to some aromatic amines and PAHs · found in certain older paints, solvents, coal tar pitches and bitumens.
• Work "as a painter" is a significant contributor to occupational cancers in construction, linked to both lung and bladder cancers.

You're rarely dealing with just one exposure, most careers stack up asbestos + silica + diesel + UV in different combinations.

3. Why recording exposure history now actually matters

Because these cancers show up decades later, what you write down in your 20s, 30s and 40s is what your future self: and their doctors and lawyers, will rely on.

Why it's worth the hassle

• IIDB and compensation: to claim Industrial Injuries Disablement Benefit or civil damages, you'll need to show work-related exposure · where, when, doing what.
• Diffuse Mesothelioma schemes: both the 2008 lump-sum scheme and the Diffuse Mesothelioma Payment Scheme (DMPS) look at your UK asbestos exposure history; claims must be made within 12 months or 3 years of diagnosis, and evidence of likely exposure is key.
• Treatment access: lung and cancer specialists will ask about past exposures to tailor tests and treatment · a clear history helps them join the dots faster.

Practical moves now

Keep a simple exposure diary (paper, notes app, spreadsheet) with:

• Employers, sites and dates.
• The main nasties: known or suspected asbestos, heavy silica dust, diesel fumes, welding fumes, coal tar/bitumen, long outdoor work with no shade/PPE.

Keep copies of any asbestos surveys, face-fit records, COSHH assessments and health surveillance results you're given.

Even if you never need it, that record costs you minutes now and could be worth a lot to you or your family later.

4. Reporting and claiming, RIDDOR, IIDB and mesothelioma schemes

RIDDOR, employer reporting

Under RIDDOR, employers must report any occupational cancer where a doctor diagnoses it and work has significantly increased the risk (for example, a lung cancer in a long-term asbestos or silica-exposed worker). This isn't on you as a worker, but it matters because it builds the data that shows where the problems are.

IIDB, Industrial Injuries Disablement Benefit

Some cancers are specifically listed as Prescribed Diseases:

• D3 · Mesothelioma.
• D8 · Lung cancer with silicosis.
• Others cover asbestos-related lung cancer where there's also asbestosis or heavy exposure in certain jobs.

Key points:

• IIDB is paid if you have a prescribed disease and a relevant work history. For mesothelioma, awards are typically high because it's so serious.
• You claim through DWP (IIDB helpline 0800 121 8379) using disease-specific forms; they will usually get medical evidence and may arrange an assessment.

Mesothelioma lump sums and DMPS

• The 2008 Mesothelioma Scheme pays fixed sums based on age at diagnosis to people with diffuse mesothelioma who can't claim under normal industrial schemes.
• The Diffuse Mesothelioma Payment Scheme (DMPS) pays people who have diffuse mesothelioma from occupational asbestos exposure in the UK, can't trace the employer or insurer, and have not already had full civil compensation. DMPS claims must be made within 3 years of diagnosis. Dependants can also claim if the sufferer has died.

A decent asbestos or industrial disease solicitor will look at IIDB + 2008 scheme + DMPS + civil claim and tell you what's realistic, the key is not to wait too long after diagnosis.

5. Straight talk, making invisible risks visible

Day to day it's easy to worry about falls and electricity and ignore the dust, fumes, sun and old boards. The numbers say otherwise: in construction, occupational cancer kills far more people than accidents, most of them from exposures that felt "normal" at the time.

You don't need to turn into a safety officer. You do need to:

• Take asbestos, silica and diesel seriously · follow the controls, walk away if they're not there.
• Treat sun cream, long sleeves and hats as PPE, not a nice-to-have.
• Start a simple exposure log for your own future, even if no one else ever sees it.

What to do next

• Today: start a simple exposure diary · even just a note on your phone with "site, dates, what I was exposed to" · and keep it going.
• If you work outdoors, get factor 30+ sun cream and wear it daily on face, ears, neck and arms · non-melanoma skin cancer from UV is one of the most preventable occupational cancers.
• If you're regularly around diesel fumes or welding, make sure there's extraction or ventilation and you're using RPE · don't assume open-air dilutes enough.
• If you've been diagnosed with a cancer you think is work-related, contact the IIDB helpline (0800 121 8379) and an industrial disease solicitor as soon as possible · time limits apply on several schemes.
