Asbestos Warning Signs
Asbestos still lurks in many UK buildings, usually harmless while left undisturbed and dangerous once fibres are released. A warning sign tells people not to drill, cut, sand or damage the material, and to report damage. These printable asbestos warning signs are general notices: danger asbestos, authorised persons only, do not disturb and report any damage. They are not the prescribed asbestos label, and a sign never replaces an asbestos survey, a management plan or a licensed contractor.

Print tips
- Print at "actual size" or 100%, not "fit to page", so the margins stay even.
- Use thicker paper or card (160gsm or more) if the sign will be handled.
- For outdoor or long-term use, laminate it or buy a rigid version.
Where to use it
- Doors to plant rooms, boiler cupboards and lofts with known asbestos
- Next to asbestos-containing panels, ceilings or pipe lagging that is being left in place
- Landlord notices for tenants and contractors
- Site hoarding where asbestos is present (as a notice, not removal signage)
- Workplace asbestos register locations
Questions
Is this the official asbestos sign?
No. These are general warning notices, not the regulated asbestos label. Asbestos labelling and signs have their own legal requirements for particular uses; see HSE guidance on asbestos (hse.gov.uk/asbestos) before relying on any sign.
Can I remove asbestos myself?
Some work needs a licensed contractor. Do not use a sign as a reason to do it yourself; see HSE guidance.
Who needs to know where asbestos is?
Duty-holders of non-domestic premises must manage asbestos and tell people who might disturb it.
Where should the sign go?
At each entrance to the area, at eye level.
