Asbestos dust and fibres have the potential to present a health risk. After a fire, asbestos clumps and some fibres may remain in the ash and may present a risk if disturbed while cleaning up after a fire.
Dust should be wetted down and protective personal equipment (dust mask, gloves and coveralls) should be worn. In the event of asbestos-containing materials being burnt on your property, a licensed asbestos removalist should be arranged to perform the clean-up work.
NSW Office of Environment & Heritage has published a guidance note.
