Accidental Asbestos Disturbance

I’ve Accidentally Disturbed Asbestos: What Should I Do?

If you have just drilled, sanded, or broken a material and you suspect it contains asbestos, stop work immediately. Do not panic — a single, brief disturbance is a manageable situation, and thousands of people deal with exactly this every year. Follow the steps below to keep yourself and your family safe while you arrange for a professional to assess the damage.

Immediate Action Plan

The priority in the first few minutes is to stop disturbing the material further and to avoid spreading any dust that has already been released. Work through these steps in order:

• Leave the room: Get everyone out and close the door.
• Seal the area: Put a damp towel at the base of the door to stop fibres from drifting.
• Switch off the air: Turn off any fans, heaters, or air conditioning.
• Don’t vacuum: Never use a domestic vacuum or a broom. This will only spread the fibres further into the air.
• Wash up: If you have dust on your skin or hair, shower immediately. Put any contaminated clothes in a sealed plastic bag.
• Keep the door shut: Don’t go back in to “check” or tidy up — leave the room sealed until a professional has assessed it.

Should I Be Worried About a One-Off Disturbance?

Asbestos-related diseases are caused by repeated or prolonged exposure to airborne fibres over years, not by a single brief incident. A short disturbance — drilling a hole, sanding a small patch, knocking a corner off a tile — is a very different situation to working unprotected with asbestos every day, which is why these illnesses are historically linked to occupational exposure in trades such as construction, shipbuilding, and insulation work.

That said, the right response is still to treat it seriously: stop, seal the room, and get the material identified properly. Acting sensibly now is what keeps a one-off incident from turning into an ongoing problem.

Why Professional Testing is Necessary

Asbestos fibres are invisible to the naked eye and can stay floating in the air for some time after a disturbance. A professional surveyor can sample the material and have it tested by an accredited laboratory to confirm whether asbestos is actually present, what type it is, and how widespread the contamination is. Acting on assumption alone — either assuming the worst and panicking, or assuming it’s fine and carrying on — is exactly what leads to either unnecessary distress or genuine ongoing risk.

What Happens When a Surveyor Attends

When you contact us about an incident like this, we will talk you through what happened and arrange to attend as quickly as we reasonably can — often within a day or two depending on your location and the nature of the disturbance. On site, we will:

• Take a sample of the disturbed material and send it for laboratory analysis to confirm whether asbestos is present and identify the fibre type
• Assess the extent of any visible debris or dust and advise on safe containment of the affected area
• Give you clear, practical guidance on next steps — whether that’s professional clean-up, encapsulation, or simply confirming the material was asbestos-free and giving you the all-clear
• Where removal or decontamination is needed, point you toward an appropriately licensed contractor for that specific job, since we are independent surveyors and don’t carry out removal ourselves

In many cases, the result is reassuring: either the material tests negative for asbestos, or the disturbance was minor enough that a straightforward clean and seal is all that’s required. Either way, you’ll have a definitive answer rather than living with uncertainty.
