Sometimes asbestos is disturbed before anyone realised it was there - a drilled wall, a broken tile, a cut sheet. In that moment, what happens next decides how many people are exposed and how far the fibres spread. Knowing the asbestos emergency procedures for accidental disturbance can dramatically limit the harm.
This guide sets out the immediate steps to take. They are the actions awareness training prepares you to carry out calmly and quickly, instead of freezing or, worse, trying to clean up.
Key takeaways
- Stop work instantly and warn everyone nearby to prevent further disturbance.
- Leave the area, restrict access and keep doors closed to contain fibres.
- Do not brush down clothing - follow the decontamination procedure.
- Report and record the incident so competent people can assess and clean up.
- Never sweep or vacuum the debris.
Stop and warn
The instant you realise asbestos has been disturbed, stop work and warn everyone nearby. The priority is to prevent any further disturbance and to stop people walking through the debris, which would crush it further and carry fibres around on boots and clothing. A calm, clear warning to everyone in the area is the first and most important action.
Leave and seal the area
Leave the area promptly, restrict access so others cannot enter, and keep doors closed where possible to contain any airborne fibres within the smallest space. Do not attempt to clean up the debris, ventilate by opening everything up, or move materials around. Containing the contamination to one area makes the professional clean-up far simpler and safer.

Decontaminate carefully
Avoid the instinctive reaction of brushing yourself down - that releases the very fibres you have collected. Follow your site decontamination procedure to remove and bag contaminated coveralls and clothing safely, so you do not carry fibres into clean areas, vehicles or home. If in doubt, keep movement to a minimum and seek guidance before leaving the area.
Report and record
Report the incident to your supervisor and the duty holder so the area can be assessed and cleaned by competent people, and so the event is properly recorded. Recording matters: it ensures the clean-up happens, documents any potential exposure for those involved, and helps prevent a repeat. The companion guide what to do if you suspect asbestos covers the response when you find, rather than disturb, suspected asbestos.
Frequently asked questions
What is the first step after disturbing asbestos?
Stop work, warn others and prevent further disturbance or movement through the debris.
Should I clean up the mess?
No. Do not sweep or hoover. Restrict access and let competent people handle the clean-up.
What should I do about my clothing?
Do not brush it down. Follow the decontamination procedure to remove and bag contaminated coveralls safely.
