What to Do If Exposed to Asbestos at Work
Asbestos exposure at work is not something to dismiss or wait out. If you suspect you’ve inhaled asbestos fibres — or you’ve just been told that a material you disturbed contained asbestos — the actions you take in the hours, days, and weeks that follow can genuinely matter for your long-term health and legal protection.
Knowing what to do if exposed to asbestos at work isn’t just useful information. For employees, managers, contractors, and duty holders alike, it’s essential. This post sets out exactly what to do, step by step, and why each action counts.
Stop Work Immediately and Leave the Area
The very first step is straightforward: stop whatever you’re doing and leave the area. Don’t attempt to clean up dust or debris yourself. Don’t sweep, vacuum with a standard hoover, or disturb the material further — all of these actions can release additional fibres into the air and make the situation significantly worse.
Once you’ve left, the area should be sealed off to prevent others from entering. If you’re a manager or supervisor, this is your immediate responsibility. Place warning signs and restrict access until a competent person has assessed the situation properly.
Remove Contaminated Clothing Carefully
If you were wearing clothing during the exposure, remove it carefully to avoid shaking fibres back into the air. Place the clothing in a sealed bag — ideally a heavy-duty red asbestos waste bag — and do not take it home to wash.
Asbestos fibres can transfer to other household members through contaminated laundry. This is a well-documented secondary exposure route that has caused disease in family members of workers who unknowingly brought fibres home on their clothes.
Wash your hands and face thoroughly with soap and water. If possible, shower as soon as practicable. Avoid touching your face before doing so.
Report the Incident to Your Employer Without Delay
Whether you’re an employee or a contractor on site, you must report the exposure to your employer or the person in control of the premises straight away. This is not optional — it’s a legal requirement under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), and it triggers a chain of protective actions that you’re entitled to.
Your employer should record the incident formally. This documentation becomes critically important if health issues emerge years or even decades later. The latency period for asbestos-related diseases can be anywhere from 15 to 60 years, meaning a written record of exposure today could be essential evidence in the future.
What Your Employer Must Do After an Exposure Incident
Once an exposure is reported, the employer has specific duties under the Control of Asbestos Regulations. These are not discretionary — they are legal obligations.
- Investigate how the exposure occurred and identify the material involved
- Arrange for the area to be assessed by a competent asbestos professional
- Ensure the affected area is not re-entered until it has been declared safe
- Review and update the site’s asbestos register and management plan
- Provide information to all affected workers about the nature of the exposure
- Consider whether the incident needs to be reported to the HSE under RIDDOR
If your employer fails to take these steps, you have the right to contact the HSE directly. You can also seek independent advice from a trade union representative or occupational health specialist.
Practical Steps for Employers and Duty Holders
If you’re the employer or duty holder dealing with an exposure incident, follow this sequence:
- Seal the area — prevent further access immediately and post clear warning notices
- Record the incident — document who was exposed, when, where, and what material was involved
- Notify the HSE — check whether the incident triggers RIDDOR reporting obligations
- Commission an emergency assessment — bring in a qualified asbestos surveyor to assess the extent of contamination
- Arrange air monitoring — if fibre release has occurred, air sampling will determine whether the area is safe to re-enter
- Arrange decontamination — licensed contractors should carry out any remediation or removal required
- Update your asbestos register — record the incident and any changes to the condition or location of asbestos-containing materials (ACMs)
- Review your management plan — consider whether additional controls or surveys are needed going forward
- Inform affected workers — they have a right to know what happened and what steps are being taken
- Consider a fire risk assessment — if the building fabric has been disturbed, this may also need updating to reflect any changes to materials or structure
Seek Medical Advice — Even If You Feel Fine
One of the most dangerous misconceptions about asbestos exposure is that if you feel well immediately afterwards, you’re in the clear. That’s not how asbestos-related disease works.
There are no immediate symptoms of fibre inhalation. The damage is cumulative and slow, and conditions like mesothelioma or asbestosis can take decades to develop. See your GP and inform them of the exposure. Ask for the incident to be recorded on your medical notes — this creates a documented history that can support any future diagnosis or compensation claim.
Ongoing Health Surveillance
If you work in a role where asbestos exposure is an ongoing risk — construction, maintenance, building management — your employer should arrange regular health surveillance. This typically involves periodic lung function tests and chest examinations carried out by an occupational health professional.
Health surveillance doesn’t prevent disease, but it can identify problems earlier, which improves outcomes. It also creates a formal record of your health status at various points in your working life, which matters if you ever need to pursue a claim.
Why Asbestos Is So Dangerous
Asbestos fibres are microscopic — invisible to the naked eye — and when disturbed, they become airborne and can be inhaled deep into the lungs. Once lodged in lung tissue, the body cannot break them down or expel them effectively. Over time, this causes scarring, inflammation, and in some cases, malignant disease.
The primary diseases linked to asbestos exposure include:
- Mesothelioma — an aggressive and incurable cancer of the lining of the lungs or abdomen, almost exclusively caused by asbestos
- Asbestosis — progressive scarring of lung tissue that restricts breathing and reduces quality of life
- Asbestos-related lung cancer — particularly associated with higher levels of cumulative exposure
- Pleural thickening — a non-cancerous condition that nonetheless causes breathlessness and significant discomfort
The HSE estimates that around 5,000 people die each year in the UK from asbestos-related diseases, making it one of the largest ongoing occupational health crises the country faces. Even a single high-dose exposure event carries risk, which is why the immediate response to any incident matters so much.
Know Your Legal Rights as an Exposed Worker
If you were exposed to asbestos at work because your employer failed in their duty of care, you may have grounds for a compensation claim. UK law provides significant protections for workers in this situation, and specialist solicitors handle these cases regularly — often on a no-win, no-fee basis.
Your employer has a legal duty under the Control of Asbestos Regulations to manage asbestos risks in the workplace. This includes conducting appropriate surveys, maintaining an asbestos register, informing workers of known hazards, and ensuring that any work likely to disturb ACMs is carried out by competent, appropriately licensed contractors.
When an Employer May Be Liable
Liability typically arises when an employer knew — or should have known — that asbestos was present and failed to take adequate steps to protect workers. Common failures include:
- Not commissioning a survey before maintenance or refurbishment work began
- Failing to share the asbestos register with contractors or maintenance staff
- Allowing unlicensed workers to disturb high-risk materials
- Not providing appropriate respiratory protective equipment (RPE)
- Ignoring signs of damaged or deteriorating ACMs
If any of these apply to your situation, document everything you can — dates, locations, who was present, what work was being carried out, and what safety measures (if any) were in place.
The Role of Asbestos Surveys in Preventing Exposure
The most effective way to prevent asbestos exposure at work is to know where the material is before anyone disturbs it. That requires a professional survey carried out by a qualified surveyor — not a visual inspection, not an assumption, and not a conversation with someone who worked in the building 20 years ago.
Different types of work require different surveys, as set out in the HSE’s HSG264 guidance.
Management Surveys
A management survey is the standard survey for occupied premises. It locates ACMs in areas likely to be disturbed during normal occupation and routine maintenance, and forms the basis of your asbestos register and management plan.
If your building was constructed before 2000 and you don’t have a current survey in place, this is where you start.
Refurbishment Surveys
Before any intrusive work — fitting out a new office, replacing pipework, upgrading electrical systems — you need a refurbishment survey. This involves accessing voids, cavities, and structural elements that a management survey wouldn’t disturb.
Skipping this step is one of the most common causes of accidental asbestos exposure during building works. It’s also one of the most avoidable.
Demolition Surveys
If a building or part of a building is coming down, a demolition survey is a legal requirement. It must be completed before demolition begins and must cover all areas of the structure, including those that are difficult to access. This is the most intrusive type of survey and must be carried out by a competent specialist.
Re-Inspection Surveys
If you already have an asbestos register, it doesn’t remain valid indefinitely. A re-inspection survey checks that known ACMs haven’t deteriorated since the last assessment. Annual re-inspections are standard practice for most premises and are a critical part of demonstrating ongoing duty of care.
What If You’re Not Sure Whether a Material Contains Asbestos?
If you come across a suspect material — textured ceiling coating, old floor tiles, pipe lagging, insulation board — treat it as though it contains asbestos until proven otherwise. That’s the precautionary principle, and it’s the right approach.
You can arrange for a sample to be taken and tested. Supernova offers a testing kit that allows you to collect a sample safely and send it to a UKAS-accredited laboratory for analysis. This is suitable only where the material can be safely sampled without creating a risk — if in doubt, bring in a qualified surveyor rather than attempting it yourself.
Never attempt to identify asbestos by appearance alone. Many ACMs look identical to non-asbestos materials, and laboratory analysis using polarised light microscopy is the only reliable method of confirmation.

Frequently Asked Questions
What should I do immediately if I think I’ve been exposed to asbestos at work?
Leave the area straight away without disturbing anything further. Remove any contaminated clothing carefully and place it in a sealed bag. Wash your hands and face with soap and water, shower as soon as possible, and report the incident to your employer without delay. Do not re-enter the area until it has been assessed and declared safe by a competent professional.
Do I need to see a doctor after a one-off asbestos exposure at work?
Yes. Even if you feel perfectly well, you should see your GP and ask for the exposure to be recorded on your medical notes. There are no immediate symptoms of asbestos fibre inhalation — diseases can take 15 to 60 years to develop. Having a documented record of the exposure is important for any future diagnosis or compensation claim.
Is my employer legally required to report an asbestos exposure incident?
Depending on the circumstances, yes. Under RIDDOR, certain incidents involving asbestos exposure must be reported to the HSE. Your employer also has duties under the Control of Asbestos Regulations to investigate the incident, update the asbestos register, arrange professional assessment of the affected area, and inform affected workers. Failure to do so is a breach of their legal obligations.
How can asbestos exposure at work be prevented in the first place?
The most effective prevention is knowing where asbestos is located before any work begins. This means commissioning the correct type of survey — a management survey for occupied premises, a refurbishment survey before intrusive works, or a demolition survey before any structure comes down. Maintaining an up-to-date asbestos register and ensuring all contractors are briefed on known ACMs are equally critical steps.
Can I claim compensation if I was exposed to asbestos at work?
If your employer failed in their duty of care — for example, by not commissioning a survey, not sharing asbestos information with contractors, or allowing unlicensed workers to disturb ACMs — you may have grounds for a compensation claim. Specialist solicitors handle asbestos exposure cases regularly, often on a no-win, no-fee basis. Document everything you can about the incident as early as possible.
