How To Take Asbestos Samples [Infographic]
A Step By Step Guide To Taking Samples
When taking asbestos samples you should always ensure the safety of yourself and those around you. Airborne asbestos fibres pose a serious health risk so you should always take extreme care when retrieving samples.
Serious diseases associated with asbestos include lung cancer, asbestosis and mesothelioma. Due to the nature of the diseases, sometimes they can lay dormant for years, making their detection harder for medical professionals.
How can I safely remove the asbestos?
Legally you can remove asbestos yourself if it is non-friable asbestos and not over 10 m2. There is a 2 hour time limit to remove the asbestos within 7 days of notification. So although you can remove it, we strongly advise not to. If you are thinking of removing asbestos contact Pro Asbestos Removal Melbourne to organise a free consultation and quote over the phone.

Asbestos is hard to identify by the human eye. Although a visual identification can sometimes be enough for some professionals, testing in a lab is always the best option.
Asbestos Safety Precautions
- Follow the guidelines provided by Environment Protection Authority in your state in order to correctly dispose of asbestos waste. The waste should be disposed only in areas designated for such waste. Asbestos waste should not be disposed in the usual garbage dump because the chance of spreading it to other areas is high. There is also a risk exposure to others.
- Have the packages with asbestos waste clearly labelled. The packages should be made of very thick, sealed polythene bags.
- While handling asbestos, ensure that it is wet to reduce chances of inhaling loose particles.
- Always put on a respirator to ensure that you don’t inhale the fibres.
- Ensure that the area is cleaned up after you have finished collecting samples. This ensures that no fibres has been left behind.
- Most importantly, consider hiring a licensed asbestos removal contactor to do the work for you. This will ensure that the work is done properly, according to the Local Government Regulations.
