What Happens If You Accidentally Disturb Asbestos?
Accidentally disturbing asbestos can release dangerous fibres into the air, creating a serious health risk. If you suspect asbestos has been damaged or disturbed in your home, workplace, or during renovation work, it’s essential to act quickly and correctly.
This guide explains what happens when asbestos is disturbed, the risks involved, and the exact steps you should take to stay safe and compliant with UK regulations.
Why Disturbing Asbestos Is Dangerous
When asbestos-containing materials are damaged, drilled, cut, or broken, tiny fibres can become airborne. These fibres are invisible to the naked eye and can be easily inhaled.
Once inhaled, asbestos fibres can remain in the lungs for many years and may lead to serious health conditions over time, including:
Asbestosis
Lung cancer
Mesothelioma

The level of risk depends on many factors:
The type of asbestos-containing material (ACM)
How much was disturbed
Duration of exposure
Ventilation in the area/External setting
Whether fibres became airborne
What To Do If You Disturb Asbestos (Step-by-Step)
If you think you have accidentally disturbed asbestos, follow these steps immediately:
Step 1: Stop Immediately
If you suspect asbestos has been disturbed:
Stop work immediately
Leave the area if safe to do so
Prevent others from entering the area
Do not sweep, vacuum or clean (standard Vacuum will spread asbestos fibres even the Hepa filtered types)
Do not try to clean it yourself
Disturbing it further increases fibre release and risk.
Step 2: Isolate the Area
Close doors and windows to limit disturbance
Turn off ventilation systems
Avoid contact or walking through the contaminated area
If dust is visible, avoid touching it.
Step 3: Do Not Attempt DIY Cleanup
Under the Control of Asbestos Regulations 2012, certain asbestos work must be handled by licensed professionals. High-risk materials (like insulation board, pipe lagging, or loose fill insulation) require a UK contractor licensed by the Health and Safety Executive (HSE). Attempting to clean asbestos without proper controls can be illegal and dangerous and risks your health and the health of others.
If you think asbestos has been disturbed, our team can attend quickly!
Step 4: Arrange Professional Assessment
A qualified asbestos surveyor can:
Assess fibre contamination
Recommend remediation steps
Carry out air monitoring if needed
If contamination is significant, a licensed removal company will conduct:
Decontamination
Air clearance testing
Certification of safe reoccupation

What If It Was a Very Small Disturbance?
If you dented or drilled one small hole or cracked a small section of material:
The health risk from a single, short exposure is usually low.
Diseases are typically linked to prolonged occupational exposure over many years and can take many years to become a problem.
However, you should still:
Get the material tested
Avoid further disturbance
Seek professional advice
Seal the material if left in situ
Remember the fibres released are not visible and can remain airborne!
Thankfully the NHS states that asbestos-related illnesses are generally associated with long-term exposure, not one-off events.
Should You See a Doctor?
You do not usually need urgent medical treatment after a brief exposure to asbestos.
There is currently:
No immediate test for asbestos exposure
No preventative treatment after short-term contact
If you’re concerned, speak to your GP for reassurance. Symptoms of asbestos-related illness typically develop after 10–60 years, not immediately.
Should You Stay in a Property With Disturbed Asbestos?
If asbestos has been disturbed, it is generally recommended to avoid the affected area until it has been properly assessed.
A qualified asbestos professional can:
Identify the material
Assess the level of risk
Recommend safe management or removal
What Are the Legal Implications?
For homeowners working on their own property:
You’re not usually prosecuted for accidental disturbance (unless you deliberately expose others or know your disturbing asbestos with others present).
You are responsible for safe disposal if removal is required.
Waste must go to a licensed hazardous waste facility.
For landlords or businesses, the legal duty is much stricter under the Control of Asbestos Regulations 2012. For UK guidance for businesses please contact us right away on 03304339680 or email info@asbestosSM.co.uk for help.
Signs You May Have Disturbed Asbestos
Common scenarios include:
Drilling into artex ceilings (pre-2000 homes)
Removing old garage roof sheets
Pulling up 1970s–1990s floor tiles
Breaking boxing around pipes
Disturbing Insulation Materials
Stripping out homes without surveys
If your property was built before 2000, asbestos could be present.
When Is Emergency Response Needed?
Call a licensed asbestos contractor immediately if:
Insulation board has been smashed or damaged
Large amounts of asbestos dust or suspect dust are visible
Debris has spread through the property
The material is soft, crumbly or friable and could be disturbed easily
They may need to conduct air testing and full decontamination.
Frequently Asked Questions
What should I do if I drilled into asbestos?
Stop work immediately, avoid disturbing the area further, leave the room, and contact a professional asbestos surveyor.
How long do asbestos fibres stay in the air?
Asbestos fibres can remain airborne for several hours, depending on air movement and ventilation.
Is it safe to clean up asbestos yourself?
No. Attempting to clean asbestos without proper equipment and training can increase the risk of exposure.
How do I know if asbestos has been disturbed?
Signs include visible dust, broken materials, or damage to surfaces known to contain asbestos. Testing is required to confirm.
Key Takeaways
Stop work immediately
Isolate the area
Do not clean it yourself
Get professional advice
Short, one-off exposure risk is generally low
Final Advice for UK Homeowners
Accidentally disturbing asbestos is frightening — but most single incidents do not result in serious health consequences specifically where dealing with bonded materials.
The important thing is responding correctly and safely. If you’re unsure, contact a qualified asbestos surveyor or licensed removal specialist for guidance.
Acting quickly protects both your health and your legal position.
