When workers come to harm from asbestos, it is often because of what they did in the first few minutes after finding it, not the discovery itself. The instinct to tidy up, take a closer look or just keep going can release a cloud of deadly fibres in seconds.
This guide focuses on what NOT to do if you find suspected asbestos - the natural, well-meaning actions that turn a manageable situation into a dangerous one. Avoiding these mistakes is just as important as knowing the correct STOP - CHECK - REPORT steps.
Key takeaways
- Never cut, drill, break, scrape or move suspected asbestos.
- Never sweep, brush, hoover or wash asbestos debris - this throws fibres into the air.
- Never take samples or attempt removal yourself.
- Never ignore it, hide it or keep working to avoid delay.
- The safe response is always to stop and report it.
Do not disturb it
Never cut, drill, break, scrape, sand or move suspected asbestos. Disturbance is what releases fibres - intact material left alone is far safer than material that has been poked, lifted or cut. This includes resisting the urge to break off a corner to see what it looks like inside. If it might be asbestos, the safest thing your hands can do is nothing.
Do not clean it up
Do not sweep, brush, hoover or wash up debris from a damaged ACM. This is one of the most dangerous things you can do, because a normal brush or vacuum blasts fibres straight back into the air and spreads them around the space. Cleaning up asbestos debris is a specialist task using proper equipment - never an ordinary site clean-up. Leave the debris exactly where it is and restrict access to the area.

Do not test or remove it yourself
Do not take samples, snap off a piece to check, or attempt any removal. Sampling is for competent surveyors and accredited labs, and removal needs specialist, often licensed contractors - this is covered in can you remove asbestos after awareness training. Awareness training never qualifies you to handle, sample or remove asbestos, no matter how small the job seems.
Do not ignore or hide it
Do not carry on working in the hope it is nothing, and do not keep quiet to avoid holding up the job. The few minutes saved are never worth the exposure, and an unreported ACM can endanger everyone who works in that space afterwards. Stop and report it - the correct response is in what to do if you suspect asbestos.
Frequently asked questions
Can I hoover up asbestos dust?
No - never. Normal vacuums and brushes throw fibres into the air. Leave the debris and report it.
Is it ok to move a small piece of suspected asbestos?
No. Even small disturbances release fibres. Do not touch or move suspected asbestos.
Can I take a sample to be helpful?
No - sampling is for competent surveyors only and disturbs the material dangerously.
What if I already disturbed it?
Stop, leave the area, prevent others from entering and report it immediately, following your emergency procedure.
Should I tell my supervisor even if I am not sure?
Yes - always report a suspicion. It is far better to check a harmless material than to ignore real asbestos.
