What to Do If Exposed to Asbestos at Work — And How to Protect Yourself Before It Happens
Asbestos remains one of the most serious occupational health hazards in the UK. Despite being banned in 1999, it still lurks in millions of buildings across the country — and workers in construction, maintenance, facilities management, and the trades encounter it every single day, often without realising it. Knowing what to do if exposed to asbestos at work could, quite literally, save your life.
This post covers where asbestos hides, your legal rights as a worker, the protective measures that genuinely make a difference, and exactly what to do if you suspect you’ve been exposed — including the steps most workers get wrong.
Where Asbestos Hides in the Workplace
Any building constructed or refurbished before 2000 could contain asbestos-containing materials (ACMs). That covers an enormous proportion of the UK’s commercial, industrial, and public building stock — schools, hospitals, offices, warehouses, and factories are all potentially affected.
Knowing where ACMs are commonly found is the first practical step in protecting yourself.
Common Locations of Asbestos-Containing Materials
- Pipe and boiler lagging (insulation)
- Sprayed coatings on ceilings, walls, and structural beams
- Ceiling and floor tiles
- Textured coatings — including Artex
- Roofing sheets and felt
- Cement panels and soffits
- Partition walls and door linings
- Electrical cable insulation and meter boxes
- Gaskets and rope seals in industrial equipment
Asbestos doesn’t advertise itself. It can look identical to non-hazardous materials — which is precisely why visual identification alone is never sufficient.
If you suspect a material might contain asbestos, stop work immediately and report it to your supervisor or health and safety representative. Do not cut, drill, sand, or disturb it in any way. Asbestos fibres are only dangerous when airborne — undisturbed ACMs in good condition may pose a lower immediate risk, but the moment they’re damaged, microscopic fibres are released that can be inhaled and lodge permanently in the lungs.
Your Legal Rights If Exposed to Asbestos at Work
UK law is clear on this. Under the Control of Asbestos Regulations, employees have strong, enforceable rights — and employers have equally clear obligations. If your employer isn’t meeting those obligations, they are in breach of regulations.
What Your Employer Must Do
- Identify the location and condition of all ACMs in the workplace
- Maintain an up-to-date asbestos register
- Produce and implement an asbestos management plan
- Ensure any work involving asbestos is carried out by appropriately licensed contractors
- Provide adequate information, instruction, and training to workers who may encounter asbestos
- Conduct suitable risk assessments before work begins in areas where ACMs may be present
- Arrange appropriate health surveillance for workers with potential exposure
Your Rights as a Worker
Right to information: You can request to see the asbestos register and management plan for your workplace. Your employer must make this available to you.
Right to refuse unsafe work: If you reasonably believe a task will expose you to asbestos without adequate controls in place, you have the legal right to refuse — without fear of dismissal or penalty.
Right to health surveillance: If your role carries significant potential for asbestos exposure, your employer must provide regular health monitoring.
Right to training: You must receive asbestos awareness training relevant to your work — not just a leaflet, but proper, documented instruction.
Right to report: You can raise concerns with the Health and Safety Executive (HSE), confidentially if necessary. Whistleblower protections apply — you cannot be lawfully dismissed or penalised for reporting genuine safety concerns.
These are legal entitlements, not optional extras. Know them and use them.
What to Do If Exposed to Asbestos at Work — Immediate Steps
Suspected or confirmed accidental exposure needs to be handled quickly and correctly. Here is exactly what to do, in order.
Step 1: Leave the Area Immediately
Leave calmly and deliberately — avoid disturbing materials further or tracking fibres into other parts of the building. Don’t rush in a way that stirs up dust, but don’t linger either.
Step 2: Remove and Bag Contaminated Clothing
Remove any contaminated clothing carefully, turning garments inside out as you do so. Place them in a sealed plastic bag and label it clearly. Do not take contaminated clothing home — this can expose family members to fibres.
Step 3: Shower Thoroughly
Wash your hair and body to remove any fibres that may have settled on your skin. Do not eat, drink, or smoke until you have fully decontaminated — fibres on hands or around the mouth can be ingested.
Step 4: Inform Your Supervisor
Report the incident verbally to your supervisor immediately, then follow up in writing. Do not rely on a verbal conversation alone — a written record protects you.
Step 5: Ensure the Incident Is Formally Documented
The following must be recorded in writing:
- Date, time, and location of the incident
- Nature of the work being carried out
- Duration and likely extent of the exposure
- What PPE was in use at the time
- Names of any other workers present
Keep a copy of the incident report. This documentation may be critical if health issues arise years or even decades down the line.
Your employer must also arrange a medical examination following any significant uncontrolled exposure. If you feel your employer is not taking the incident seriously, report it directly to the HSE. You can do this anonymously.
Practical Measures That Genuinely Reduce Your Risk
Regulation provides the framework — but on the ground, it’s day-to-day practices that keep workers safe. Here’s what actually makes a difference.
Personal Protective Equipment (PPE)
When working in areas where asbestos exposure is a confirmed or possible risk, the right PPE is non-negotiable. Your employer must provide it at no cost to you.
- Respiratory protection: A minimum FFP3-rated disposable mask, or for higher-risk work, a half-face or full-face respirator with P3 filters. Standard dust masks are completely inadequate for asbestos fibres.
- Disposable coveralls: Type 5 disposable overalls prevent fibres settling on clothing and being carried out of the work area.
- Gloves and boot covers: These prevent contact contamination and assist with decontamination.
PPE must fit correctly. A poorly fitted respirator offers little real protection — face-fit testing is a legal requirement for tight-fitting respiratory equipment, not a recommendation.
Safe Working Practices
- Wet methods: Dampening materials before and during work reduces fibre release significantly.
- HEPA-filtered vacuums: Standard vacuum cleaners will release asbestos fibres back into the air. Only H-class or M-class vacuums are appropriate.
- Controlled work zones: Asbestos work should be isolated from other areas to prevent fibres spreading.
- Minimal disturbance: Work methodically and deliberately — rushed or aggressive working increases fibre release.
- Decontamination on exit: Contaminated coveralls must be removed inside the work area, turned inside out, and bagged before leaving.
- Proper waste disposal: Asbestos waste is classified as hazardous. It must be double-bagged in labelled bags and disposed of at a licensed facility.
Why Asbestos Surveys Matter — And What Type You Need
Before any refurbishment, maintenance, or demolition work begins on a pre-2000 building, a professional asbestos survey should have been completed. If your employer is asking you to start work without one — particularly in an older building of unknown construction history — that’s a serious red flag.
There are different survey types for different situations:
- A management survey is used for the ongoing management of ACMs in occupied buildings.
- A refurbishment survey is required before any renovation or intrusive maintenance work takes place.
- A demolition survey is required before any demolition work begins.
You have every right to ask whether a survey has been completed before you pick up a tool. If you’re unsure whether a material might contain asbestos, asbestos testing by a UKAS-accredited laboratory is the only reliable way to confirm it. Guesswork is not an acceptable risk assessment.
For workers who want to understand a specific material before calling in a professional, an asbestos testing kit allows you to safely collect a sample for laboratory analysis. However, sampling must be done carefully and correctly — if you’re not confident, use a professional surveyor.
Health Monitoring: What to Expect and Why It Matters
Asbestos-related diseases can take decades to develop after exposure. That’s what makes them so insidious — and why ongoing health monitoring is so important for workers in at-risk trades.
What Health Surveillance Involves
For workers regularly exposed to asbestos, health surveillance is a legal requirement under the Control of Asbestos Regulations. This typically includes:
- A baseline medical assessment when starting work involving asbestos
- Periodic medical examinations, which may include lung function tests
- Review by an appointed doctor with expertise in occupational health
- Maintained health records, which must be kept for a minimum of 40 years
You have the right to access your own health records. If you change employer, ensure your new employer is aware of your exposure history — and keep your own copies of any records provided to you.
Symptoms You Should Never Ignore
If you’ve worked in environments where asbestos may have been present, seek medical attention promptly if any of the following develop:
- A persistent dry cough that doesn’t resolve
- Increasing breathlessness, particularly during physical activity
- Chest pain or tightness
- Unexplained fatigue or weight loss
- Difficulty swallowing
- Swelling in the face or neck
Always tell your GP about your occupational history, including any potential asbestos exposure. This information directly affects how your symptoms will be investigated and what tests will be ordered.
Asbestos Awareness Training: What You Should Be Receiving
Training isn’t something your employer offers as a courtesy. For workers liable to encounter asbestos, it’s a legal requirement under HSE guidance and the Control of Asbestos Regulations.
Proper asbestos awareness training should cover:
- What asbestos is, where it’s found, and why it’s dangerous
- The different types of asbestos and which are most hazardous
- How to recognise common ACMs
- The health risks associated with exposure
- Your employer’s asbestos management procedures
- What to do if you discover suspected asbestos
- Emergency procedures in the event of uncontrolled exposure
Training must be documented and refreshed regularly. If you’ve never received any formal asbestos awareness training and your work involves older buildings, raise this with your employer directly and in writing.
Are You Self-Employed? The Rules Still Apply
Self-employed workers must comply with the Control of Asbestos Regulations in exactly the same way that employed workers must be protected. If you carry out work on buildings where asbestos may be present, you must have appropriate training, follow safe working procedures, use correct PPE, and ensure any materials you suspect are ACMs are properly tested before you disturb them.
Being your own boss does not exempt you from the duty to protect yourself — or others who may be affected by your work. The HSE takes enforcement action against sole traders and self-employed contractors as well as larger organisations.
If you’re unsure whether a material you’re about to work on contains asbestos, arrange asbestos testing before proceeding. The cost of a test is negligible compared to the consequences of uncontrolled exposure.

Frequently Asked Questions
What should I do immediately if I think I’ve been exposed to asbestos at work?
Leave the area calmly without disturbing materials further. Remove and bag any contaminated clothing, shower thoroughly, and report the incident to your supervisor straight away — in writing as well as verbally. Make sure a formal incident report is completed and keep a copy for yourself. Your employer must arrange a medical examination following any significant uncontrolled exposure.
Can I refuse to work if I think asbestos is present?
Yes. Under the Control of Asbestos Regulations, you have the legal right to refuse work you reasonably believe will expose you to asbestos without adequate controls in place. You cannot be lawfully dismissed or penalised for doing so. If your employer pressures you, raise the matter with the HSE — you can do this confidentially.
How do I know if a material at work contains asbestos?
You cannot tell by looking at it. Visual identification is never reliable. The only way to confirm whether a material contains asbestos is through laboratory testing by a UKAS-accredited facility. A professional surveyor can collect samples safely, or you can use an asbestos testing kit to collect a sample yourself if you’re confident in doing so correctly.
Does my employer have to tell me if there’s asbestos in my workplace?
Yes. Under the Control of Asbestos Regulations, employers must maintain an asbestos register and management plan, and must make this information available to workers who may encounter ACMs. You have the right to request this information — your employer is legally obliged to provide it.
What health problems can result from asbestos exposure at work?
Asbestos exposure can cause mesothelioma (a cancer of the lining of the lungs and other organs), lung cancer, asbestosis (scarring of the lung tissue), and pleural thickening. These conditions typically take 20 to 50 years to develop after exposure, which is why early documentation of any exposure and regular health surveillance are so important. If you develop a persistent cough, breathlessness, or chest pain and have a history of working around older buildings, tell your GP about your occupational history immediately.
