What is asbestos, and why does asbestos encapsulating matter?

Asbestos is a naturally occurring mineral once widely used in construction due to its durability, fire-resistance, and insulating properties. However, it was later discovered exposure to asbestos fibres could cause serious health problems such as lung cancer, mesothelioma, and asbestosis. As a result, many countries have banned the use of asbestos in construction and other industries to protect people from the dangers of asbestos.

Despite the health risks associated with asbestos, it still exists in many older buildings and structures. Asbestos-containing materials (ACMs) such as insulation, ceiling tiles, and flooring can become friable or easily crumble, releasing asbestos fibres into the air. To prevent this from happening, asbestos encapsulating can be done.

Asbestos encapsulation is a process in which a material is applied over ACMs to create a seal that prevents the release of asbestos fibres. The encapsulating material can be a liquid coating, a spray, or a blanket-like material attached to the surface of the ACMs. Encapsulation aims to create a barrier that prevents asbestos fibres from escaping into the air.

Encapsulation is an effective method of asbestos abatement because it is less intrusive than removal. Removal of ACMs can be expensive and disruptive, as it involves tearing out walls, ceilings, and other parts of a building. Furthermore, removal can release a significant amount of asbestos fibres into the air, which can pose a risk to workers and occupants of the building.

On the other hand, asbestos encapsulating is a less invasive process that can be done without disturbing the ACMs. Encapsulating materials can be applied directly over the surface of the ACMs, creating a seal that prevents the release of fibres. In addition, encapsulation can be less expensive than removal, making it an attractive option for building owners and managers.

One important consideration when using asbestos encapsulation is the choice of encapsulating material. The material should be able to withstand the environment in which it is being used, and it should be able to adhere to the surface of the ACMs. Some typical materials used for encapsulation include liquid coatings, such as epoxy or latex, and blanket-like materials, such as fibreglass or cloth.

Another important consideration is the effectiveness of asbestos encapsulation. The encapsulating material should be able to create a seal that prevents the release of fibres for a significant period. The effectiveness of encapsulation can be tested through air monitoring and visual inspections.

Asbestos encapsulation is not a permanent solution to the asbestos problem in buildings. Over time, encapsulating materials can deteriorate, and ACMs can become damaged or disturbed. Therefore, it is essential to regularly inspect encapsulated materials to ensure that they are still effective. If encapsulated materials are found to be deteriorating or damaged, they may need to be repaired or removed.
