Asbestos is a fibrous silicate mineral that was once used extensively in building materials due to its strength, flexibility and resistance to heat, electricity and corrosion. Unfortunately, asbestos removal is now known to be a hazardous material that can lead to serious health issues such as mesothelioma. It is therefore essential to have any suspected asbestos-containing materials ACMs inspected and tested by a professional, and to take steps to ensure that they are removed or encapsulated in accordance with appropriate regulations.
ACMs are found in a wide variety of materials in both commercial and residential buildings, including roofing, floor tiles, sheetrock, insulation and paint. The risk of exposure arises when these materials are disturbed and airborne fibres are released. While it is possible to replace ACMs, encapsulation or removal is the best course of action when asbestos is present in areas that will be disturbed during renovation or construction.
During the asbestos removal process, professionals will use various tools to physically remove the ACMs and cut them into smaller pieces. This is done to ensure that the fibres are not spread into the air during removal, and also to limit the amount of asbestos dust generated during the process. The ACMs will then be placed in durable, sealed waste containers for transport and disposal. The containers will be sealed and labeled according to EPA guidelines, and the container will be transported to a site that is authorised by the EPA to accept asbestos waste.
It is important to note that asbestos removal should always be undertaken by a trained, qualified asbestos professional. Homeowners that attempt DIY removal are at risk of exposing themselves and their family to the dangerous fibres, which can cause serious illnesses such as mesothelioma.
Professionals will follow strict adherence to all relevant safety and environmental guidelines, and will ensure that any potential asbestos contamination is contained within the work area. They will test the air for contaminants before, during and after removal, and will clean the work area to a state of good repair before declaring it safe.
After the removal or encapsulation of asbestos, the area will be surveyed again by an independent air monitor to ensure that all contaminants have been contained. The area will then be sealed off to prevent demolition dust from escaping into adjacent areas, and all windows and exhaust ducts will be closed. Only once the area has been deemed safe by the air monitor will it be ready for renovation and construction.
It is important to remember that ACMs only pose a hazard when they are airborne and you breathe them in. If you leave the materials in place and keep them in good condition, they are not a health threat. However, it is still recommended that you have all suspect asbestos-containing materials inspected and tested on a regular basis by a professional.
