According to Safe Environments , if there is a house built in Sydney before 1990, it is probable that the house will contain some form of asbestos material. Asbestos testing can identify potential asbestos containing materials within the house. Bonded asbestos when left and maintained in a good condition does not pose a health risk unless the asbestos containing material is deteriorated or disturbed such that it liberates fibres into the air.
The cost of asbestos testing is inexpensive compared to that of the extra cost imposed to remove the asbestos safely. The cost of asbestos removal is underestimated and should be considered as part of the purchase price of the house if they plan to renovate. Asbestos testing also provides peace of mind as to confirm whether the material contains asbestos or not.
Testing for the presence of asbestos cannot be confirmed by just looking at the material with the naked eye. Asbestos testing involves viewing the fibres under a polarised light microscope under different conditions to confirm the type of asbestos, if present. If there is damage to materials, asbestos testing the air can assess the relative risk of respirable fibres with that of the national exposure standard.
Many Sydney councils also require an asbestos survey and asbestos testing to be carried out to ensure that people are aware of the potential risk while renovating that house. Once the results of asbestos testing are known, the results including the location and condition of the material is recorded within an asbestos register.
