This safety alert reminds you never to use high-pressure water or compressed air to clean asbestos roofs.


In April 2017, a contractor used a high-pressure water to clean an asbestos roof and caused widespread asbestos contamination. Neighbours were forced to vacate their properties during the clean-up process.

If asbestos is disturbed, you are at risk of inhaling airborne asbestos fibres.

Action required

  • Never use high-pressure water or compressed air on asbestos products.
  • Be careful when working on asbestos roofs – they are brittle and you can easily fall through.
  • Follow legal and safety requirements to manage asbestos.
  • Use a licensed asbestos removalist.
