What to Do If Exposed to Asbestos at Work: A Practical Guide for UK Workers
Asbestos exposure at work is not a situation you can afford to deal with tomorrow. If you suspect you’ve breathed in asbestos fibres — or you’ve been working in an area where asbestos-containing materials were disturbed — the actions you take in the next few hours and days can genuinely affect your long-term health. This guide covers exactly what to do if exposed to asbestos at work, what your legal rights are, and how to protect yourself and your colleagues going forward.
Stop Work Immediately and Leave the Area
The moment you suspect asbestos has been disturbed, stop what you’re doing. Don’t continue drilling, cutting, or breaking into materials — every second of continued disturbance increases the concentration of fibres in the air.
Leave the affected area calmly and without rushing, as hurried movement can stir up additional dust. Close any doors behind you to help contain the area as much as possible.
Do not re-enter the area for any reason until it has been assessed and cleared by a licensed professional. This applies to you, your colleagues, and anyone else who might otherwise wander in.
Contain the Area and Prevent Others from Entering
Once you’re out, the area needs to be secured immediately. Put up physical barriers and clear signage to prevent anyone else from entering. If your workplace has a facilities or maintenance team, alert them straight away so they can assist with isolation.
Turn off any ventilation or air conditioning systems serving the affected area if it is safe to do so. Running ventilation can spread fibres to other parts of the building, turning a localised incident into a much wider problem.
Report the Incident to Your Employer Without Delay
Your employer has a legal duty under the Control of Asbestos Regulations to manage asbestos risks in the workplace. Reporting the incident immediately is not optional — it is a requirement, and it protects both you and your colleagues.
Tell your supervisor or safety representative exactly what happened: where you were working, what materials were disturbed, how long you were in the area, and whether you were wearing any respiratory protection at the time. The more detail you provide, the better the response can be tailored to the situation.
Your employer should then arrange for a licensed asbestos surveyor to assess the area, take air monitoring readings where necessary, and confirm whether fibres were released and at what level.
What Your Employer Must Do
Under the Control of Asbestos Regulations, employers have clear obligations when an asbestos incident occurs. These include:
- Stopping all work in the affected area immediately
- Arranging for a licensed contractor to assess and, if necessary, remediate the area
- Notifying the Health and Safety Executive (HSE) if the exposure was significant
- Recording the incident in the workplace accident and incident log
- Reviewing the asbestos management plan and updating it if required
- Providing affected workers with clear information about what happened and what steps are being taken
If your employer fails to act, you have the right to contact the HSE directly. Workers should never feel pressured to continue in an area where asbestos exposure is suspected.
Decontaminate Properly Before Leaving the Site
If you were in an area where asbestos was disturbed, your clothing, hair, and skin may have fibres on them. Decontamination is essential — not just for your own protection, but to avoid carrying fibres home and exposing your family.
If disposable coveralls were worn, remove them carefully by rolling them inward from the shoulders, turning them inside out as you go. This keeps any fibres trapped inside the suit rather than releasing them into the air.
Personal Decontamination Steps
- Remove disposable PPE in the designated decontamination area, rolling rather than pulling it off
- Place all disposable PPE in sealed, labelled asbestos waste bags — do not put it in general waste
- Wipe down non-disposable items such as boots with damp cloths before removing them from the area
- Wash your hands and face thoroughly with soap and water
- Shower as soon as possible — do not travel home in potentially contaminated clothing
- Bag any clothing that may have been contaminated and arrange for it to be laundered separately, or dispose of it if heavily contaminated
Do not eat, drink, or smoke in or near the affected area. Asbestos fibres can be ingested as well as inhaled, and this is an easily avoided additional risk.
Seek Medical Advice — Even If You Feel Completely Fine
This is the step many workers skip, and it is a serious mistake. Asbestos-related diseases — including mesothelioma, asbestosis, and lung cancer — can take 20 to 50 years to develop. You will not feel ill immediately after exposure, and that does not mean nothing has happened.
Visit your GP as soon as possible and explain that you have been potentially exposed to asbestos at work. They will record the incident in your medical notes, which is essential for any future health monitoring or compensation claims.
Occupational Health Referral
Your employer may have an occupational health provider. If so, ask to be referred. Occupational health professionals can assess your level of exposure, advise on appropriate monitoring, and flag any symptoms that should be investigated further.
Even if there is no occupational health service available through your employer, your GP can refer you to a specialist if needed. The key is to have the exposure documented formally and to begin health monitoring as early as possible.
Symptoms to Watch For
In the weeks and months following potential exposure, pay close attention to any of the following:
- A persistent dry cough that does not improve over time
- Shortness of breath, particularly during physical activity
- Chest tightness or pain
- Fatigue that seems disproportionate to your activity levels
- Unexplained weight loss
None of these symptoms in isolation necessarily indicate an asbestos-related condition, but any of them warrant a conversation with your GP — particularly if you’ve had a known or suspected exposure.
Understanding Why Asbestos Exposure Is So Serious
Asbestos was used extensively in UK buildings constructed before 2000. It appeared in everything from ceiling tiles and pipe lagging to floor tiles, roof sheets, and spray coatings on structural steelwork. Because it was so widely used and so effective as an insulator and fire retardant, it remains present in a huge number of commercial and industrial buildings across the country.
The danger comes when asbestos-containing materials (ACMs) are disturbed. When fibres become airborne and are inhaled, they can become lodged in the lungs and surrounding tissue. The body cannot break them down, and over time they can cause severe scarring, inflammation, and ultimately life-threatening disease.
Who Is Most at Risk?
Certain occupations carry a significantly higher risk of accidental asbestos exposure. If your job regularly takes you into older buildings, understanding the asbestos risk in those environments is part of working safely. Those most at risk include:
- Construction workers — particularly those working on older buildings during refurbishment or demolition
- Plumbers and heating engineers — who frequently encounter asbestos lagging around old pipes and boilers
- Electricians — who drill into walls and access ceiling voids where ACMs may be present
- Carpenters and joiners — who cut and sand materials that may contain asbestos
- Roofers — who work with asbestos cement sheets on older industrial and agricultural buildings
- Facilities managers and maintenance staff — who carry out day-to-day repairs in buildings with unknown asbestos histories
A professional asbestos survey in London or any other city can give building managers the information they need to protect their workforce before work begins.
Your Legal Rights as a Worker
UK law is clear on this. The Control of Asbestos Regulations place duties on employers and building owners to manage asbestos safely. As a worker, you have the right to:
- Be informed of any known asbestos in your workplace and its location
- Receive appropriate training before working in areas where asbestos may be present
- Be provided with suitable personal protective equipment at no cost to you
- Refuse to work in an area you reasonably believe poses an asbestos risk without adequate protection
- Report concerns to the HSE without fear of reprisal
HSG264, the HSE’s guidance on asbestos surveying, sets out the standards that surveys and management plans must meet. If your employer cannot produce an up-to-date asbestos register or management plan, that is a significant compliance failure — and one you are entitled to challenge.
Making a Compensation Claim
If you develop an asbestos-related condition as a result of workplace exposure, you may be entitled to compensation. This is a complex area of law, and you should seek advice from a solicitor who specialises in industrial disease claims.
The earlier your exposure is documented — through medical records, incident reports, and occupational health records — the stronger any future claim will be. This is another reason why reporting the incident and visiting your GP immediately are so important. Documentation created at the time of exposure carries far more weight than accounts reconstructed years later.
Preventing Future Exposure: What Should Be in Place
Once an incident has occurred, the focus shifts to ensuring it does not happen again. This means reviewing the systems and processes that should have prevented the exposure in the first place.
Asbestos Surveys and Management Plans
Every non-domestic building constructed before 2000 should have an up-to-date asbestos survey and a written management plan. The survey identifies where ACMs are located, what condition they are in, and what risk they pose. The management plan sets out how those materials will be managed, monitored, and — where necessary — removed.
If your workplace does not have one, or if the existing survey is out of date, commissioning a professional survey is the most important step you can take. For businesses in the North West, an asbestos survey in Manchester from a qualified team will identify all ACMs and provide the information needed to manage them safely and compliantly.
Worker Training
The Control of Asbestos Regulations require that workers who may encounter asbestos during their work receive appropriate training. This is not a one-off exercise — it should be refreshed regularly and updated whenever working practices or locations change.
Training should cover:
- What asbestos is and where it is commonly found
- The health risks associated with exposure
- How to identify potentially asbestos-containing materials visually
- What to do if asbestos is suspected or disturbed
- How to use and dispose of PPE correctly
- Reporting procedures within the organisation
The Role of Licensed Contractors
Some asbestos work can only be carried out by contractors licensed by the HSE. This includes the removal of most sprayed coatings, lagging, and other high-risk ACMs. Using unlicensed contractors for notifiable work is a criminal offence, and it puts workers and building occupants at serious risk.
If your workplace is in the Midlands and requires asbestos assessment or management, an asbestos survey in Birmingham carried out by accredited surveyors will ensure you have accurate, compliant information before any work begins.

Frequently Asked Questions
What should I do immediately if I think I’ve been exposed to asbestos at work?
Stop work immediately and leave the affected area without rushing. Do not re-enter. Secure the area to prevent others from entering and turn off any ventilation serving the space if it is safe to do so. Report the incident to your supervisor straight away, and visit your GP as soon as possible — even if you feel completely well. Early documentation of the exposure is essential for your health records and any future claims.
Do I need to see a doctor after asbestos exposure even if I have no symptoms?
Yes, absolutely. Asbestos-related diseases such as mesothelioma and asbestosis can take decades to develop. You will not experience symptoms immediately after exposure. Visiting your GP creates a formal record of the incident in your medical notes, which is critical for health monitoring and any future compensation claim. Do not wait for symptoms to appear before seeking advice.
Can I refuse to work in an area where asbestos has been found?
Yes. Under the Control of Asbestos Regulations, you have the right to refuse to work in an area you reasonably believe poses an asbestos risk without adequate protection in place. You are also protected from reprisal for raising concerns with your employer or reporting to the HSE. Your employer is legally required to manage asbestos risks and cannot compel you to work in an unsafe environment.
What is my employer legally required to do after an asbestos exposure incident?
Your employer must stop all work in the affected area, arrange for a licensed contractor to assess and remediate the space, notify the HSE if the exposure was significant, record the incident formally, and review and update the asbestos management plan. They must also provide affected workers with clear information about what happened and the steps being taken. Failure to do so is a breach of the Control of Asbestos Regulations.
How do I know if my workplace has an asbestos management plan?
You have the right to ask your employer or building manager to see the asbestos register and management plan. Every non-domestic building built before 2000 should have one. If your employer cannot produce an up-to-date survey and plan, that is a compliance failure. You can raise this with your safety representative or report it to the HSE. Commissioning a professional asbestos survey is the first step to putting proper management in place.
