Does your roof have asbestos Here are some guidelines to help you. Asbestos is a collective term referring to six naturally occurring minerals usually mined from the earth. They include Amosite Chrysotile Thermolite Actinolite Anthrophylite and Crocidolite. Asbestos can be divided into bonded asbestos and friable asbestos. Bonded asbestos consist of asbestos fibers embedded within a cement matrix and were commonly used in residential settings. Friable asbestos were mostly used for industrial settings. All asbestos break readily into tiny fibers that can only be identified microscopically. These fibers are indestructible and thus the need for the safe removal of asbestos containing products. Asbestos is extremely hazardous when friable as it readily crumbles forming tiny fibers. In Australia between 1950s and 1980s asbestos was used extensively in residential buildings and also in textile industries. Asbestos materials were widely used then because of their durability and their resistance to fire and due to the gap in knowledge of their toxicity.

Many parts of Australia were mining towns. Many buildings that still stand today in Brisbane were built with materials containing asbestos like in their roofings insulation materials and floor tiles. It was recently discovered by officials that many homes still contain remnants of asbestos. It is therefore important to know the signs if your roof contains asbestos and have a knowledge in the asbestos removal tips and advice. Signs your roof may have asbestos Inspecting the roof visually is insufficient to confirm the presence of asbestos in roofs. Therefore samples of suspected asbestos fibers need to be sent for lab analysis. This can be done by contacting National Association of Testing Authorities NATA. The methods of analysis include Polarized Light Microscopy PLM and Transmission Electron Microscopy TEM. Here are some guidelines to help you determine if your roof contains asbestos: -  l. Check for asbestos marking on the roofing or in their package materials. If the house was built or renovated before mid 1980s it is most likely to have asbestos roofing. If the house was built or renovated between mid 1980s and 1990 it is most likely to have asbestos roofing.  2. If the roof is made of flat corrugated roofing material.  3. If the roof is made of bitumen roofing material.

Asbestos removal tips and advice Asbestos readily break forming tiny fibers that are indestructible. These tiny fibers pose the greatest health risk because they remain suspended in the air and are readily inhaled. This increases the risk of lung cancer asbestosis and mesothelioma. It is important to note that in Brisbane a license is required to remove friable asbestos or if removing more than 10kg of non-friable asbestos. You can hire professional contractors to remove asbestos at Here are some asbestos removal tips and advice to guide you:-  Wear a respirator to protect you from inhaling the tiny asbestos fiber. The recommended respirator is one with P100 cartridge filters and dusk masks are not to be used.  Wear disposable clothes that you will dispose after use to minimize contamination.  Collect any debris from the roof while removing the roof by placing plastic clothes around the house.  Keep other people away from the area where the asbestos containing material is being removed.  Wet the asbestos containing materials before removing them and keep wetting them during removal.  Avoid contamination by tracking material into the house.  Avoid breaking up the roofing material and therefore it is advisable to work slowly to minimize breakage.

 Avoid dropping material by lowering them slowly to the ground.  Wrap the roofing in a 0.2mm thick polyethylene sheeting or in skip bins and label with an appropriate warning like caution-asbestos for easy disposal.  Wash off the tools used and dispose off the cover clothes used. Wash thoroughly any exposed skin to avoid further contamination. Disposal of the asbestos is done at a landfill site managed by local council that can receive asbestos waste only by licensed asbestos contractors. There are registered workers that specialize in asbestos removal in Australia it is more advisable to solicit their expertise than remove the asbestos on your own. As a Brisbane resident it is therefore important to know the signs your roof may have asbestos because of the extensive use of asbestos materials in construction between the mid 1950s to the 1980s. The risk associated with contamination by asbestos fibers is well known to us as well as the health hazards posed by asbestos. It is also important to know some safety measures to take while removing asbestos as there can be serious contamination during the removal process. It is preferred that you get a registered asbestos contractor to remove and dispose off the asbestos material. References:- 1. 2.
