Asbestos is a common term describing a variety of naturally occurring silicate minerals. It was a popular building material up until the 1990s because of its exceptional insulating, fire-resistant and reinforcing properties.
Asbestos poses a risk if it is no longer adequately contained in the material it came in (such as due to damage, being cut or drilled into during building work, home maintenance or wear and tear).
Left undisturbed, asbestos is safe – but if it is exposed or damaged, it can be harmful.
The highest risk of exposure to asbestos in the home is through home renovating, by cutting or drilling through asbestos-cement sheeting or sanding down asbestos-backed linoleum or tiles. Left undisturbed, these materials pose a negligible risk as long as they are in good condition and it is recommended that asbestos-containing material in good condition be left alone.
Information below is from Asbestos Aware. This is a website that Selwyn District Council helped to create through its representation and funding provided to the Canterbury Joint Waste Committee.
If testing has confirmed the presence of asbestos in your home and you are starting renovation, demolition or repair work, you can:
- Leave it undisturbed if it is in a good stable condition and won’t be impacted by the renovation work or
- Engage a competent contractor to put in place other options for dealing with asbestos such as sealing, encasing or complete removal.
Asbestos left undisturbed, in good condition or sealed is relatively safe – but if it is easily crumbled, broken down, or damaged or if you intend to drill it, sand it or break it up, it can be harmful and needs specialist attention.
Asbestos Aware strongly advises you to use professional asbestos removal companies to undertake the removal, transportation and disposal. They are fully trained and equipped to complete this work and to manage the clean-up. Residue from asbestos left in your home can cause health issues in the future – that’s why it’s so important to be asbestos aware.
There are certain types of work with asbestos containing materials that by law can only be carried out by, or under the direct supervision of, someone who holds a Certificate of Competence for Restricted Work with Asbestos issued by WorkSafe NZ. WorkSafe NZ strongly recommends that all asbestos removal work is completed by an approved provider.
