Asbestos doesn't announce itself. It sits quietly in ceilings, pipe lagging and floor tiles across thousands of Irish buildings put up before 2000 — completely harmless until the moment someone drills, cuts or breaks it. This guide walks through where it lurks, how to read the warning signs, and the steps the HSA expects you to take.
Why this still matters in 2026
Ireland banned the import and use of asbestos in 1999, so it's tempting to file it under "old news". The problem is that the buildings are still standing. Schools, hospitals, offices, factories and homes constructed before the millennium can all contain asbestos-containing materials (ACMs) — and the fibres only become dangerous when the material is disturbed.
That's why asbestos remains the single biggest cause of work-related deaths. The people most at risk aren't specialist removers in full protective suits — they're the electricians, plumbers, joiners and maintenance crews who run into it by accident, without realising what they've cut into.
Where asbestos hides
Asbestos was prized for being cheap, fire-resistant and a brilliant insulator, so builders put it almost everywhere. Tap a hotspot below to see the usual suspects in a typical older building.
Cement sheets & gutters
Corrugated roofing, soffits, downpipes and flue panels often used asbestos cement. Weathered and cracked sheets are a classic disturbance risk.
The three types you'll hear about
People often talk about asbestos by colour. All three are dangerous and all are banned — colour alone should never be used to decide something is "safe". Only a competent surveyor with lab testing can confirm what a material really is.
White
The most widely used form — found in cement, ceilings, gaskets and insulation.
Brown
Common in insulation boards and ceiling tiles; rougher, more fibrous appearance.
Blue
The most hazardous — used in sprayed coatings and pipe lagging. Extremely friable.
If a building went up before 2000 and you're about to disturb the fabric of it — assume asbestos could be present until a survey proves otherwise. Assumption is free. Exposure is permanent.
If you think you've found it — STOP
Discovering a suspect material isn't an emergency if you handle it calmly. The danger comes from carrying on regardless. Follow these steps in order.
Stop work immediately
Put the tools down. Don't drill, cut, sand or sweep — that's exactly what releases fibres into the air.
Keep everyone out
Clear the area, close doors and stop others from walking through. Don't try to clean anything up yourself.
Report it
Tell your supervisor or the site's safety officer straight away so the area can be controlled and logged.
Get it assessed
A competent person arranges a survey and, if needed, licensed removal. Work only restarts once it's confirmed safe.
What the HSA expects
Under the Safety, Health and Welfare at Work (Exposure to Asbestos) Regulations 2006(as amended in 2010), employers and duty holders must locate and manage ACMs and make sure anyone who could disturb them is properly trained. In practice that means:
- Knowing where asbestos is — or could be — before work starts
- Giving asbestos awareness training to at-risk workers
- Having clear procedures for stopping work and reporting suspect materials
- Using licensed contractors for removal of higher-risk materials
