Asbestos Removal: A Complete Guide to Safe and Professional Removal

Asbestos was once a widely-used material in Australian homes and buildings due to its fire-resistant and insulating properties. However, it has since been linked to severe health hazards, such as mesothelioma, lung cancer, and asbestosis. Asbestos fibres, when inhaled, can cause life-threatening diseases. This is why safe and professional asbestos removal is crucial for anyone undertaking renovations, demolitions, or maintenance on properties built before the 1990s.

At Identifibre, we provide expert asbestos testing, air monitoring and post removal clearance inspections, across Australia, ensuring compliance with state and territory safety regulations and keeping your home or workplace safe from airborne asbestos exposure.

What is Asbestos and Why is it Harmful?

Asbestos refers to a group of naturally occurring minerals that were commonly used in building materials across Australia until the 1980s. These materials are not dangerous when undisturbed, but when broken or damaged, they release microscopic fibres that can be easily inhaled. These fibres lodge in the lungs, causing serious diseases that may not manifest until decades later.

Some of the asbestos-related diseases include:

  • Mesothelioma: An aggressive form of cancer that affects the lining of the lungs or abdomen.
  • Asbestosis: A chronic lung disease caused by scarring of lung tissue due to asbestos fibres.
  • Lung Cancer: Long-term exposure to asbestos greatly increases the risk of developing lung cancer.

As there is no safe level of asbestos exposure, it is crucial to address any asbestos-containing materials (ACMs) with extreme caution.

Where is Asbestos Found?

  • Roofing materials: Corrugated asbestos sheets and tiles.
  • Cement sheeting: Often used in walls, ceilings, eaves and fences.
  • Insulation: Around pipes, boilers, and in some old heaters.
  • Vinyl flooring and adhesives: Vinyl tiles and underlays may contain asbestos​.

If your property was built before 1990, it’s wise to assume asbestos may be present and to have your property professionally tested.

When Should You Consider Professional Asbestos Removal?

It’s important to note that asbestos does not always need to be removed. In some cases, materials containing asbestos may remain undisturbed and pose minimal risk. However, removal becomes necessary when:

  • The material is damaged or deteriorating, making it more likely to release fibres.
  • You’re planning a renovation, demolition, or major maintenance that will disturb asbestos-containing materials.

If any of these conditions apply, it’s critical that asbestos removal be conducted by licensed professionals.

Where Is Asbestos Found?

    Even though asbestos is banned in many countries, it can still be found in many older buildings, homes, and various materials, including:

    • Roofing and siding materials
    • Vinyl floor tiles
    • Pipe insulation
    • Ceiling tiles
    • Fireproofing materials
    • Cement sheeting
    • Linings behind and below ceramic tiles
    • Within electrical cupboards and older electrical components

    The Asbestos Removal Process in Australia: Step-by-Step

    Asbestos removal is a carefully controlled process that must follow strict safety protocols as outlined by EPA Victoria and WorkSafe Australia. Here’s an overview of how the process works:

    1. Inspection and Testing

    An asbestos hygienist or consultant will inspect the suspected areas and take samples to be tested at a NATA accredited laboratory. This testing will determine the presence and type of asbestos​.

    2. Preparation of the Area

    Before removal begins, the work area is sealed off to prevent any asbestos fibres from spreading to other parts of the building. Plastic sheeting is commonly used to cover floors and walls, and negative air pressure units may be set up to filter the air, this is a requirement for the removal of friable asbestos-containing materials.

    3. Asbestos Removal

    The asbestos-containing materials are carefully removed by licensed removal professionals using specialised tools and protective equipment.

    4. Disposal of Asbestos

    Asbestos waste is double-bagged in heavy-duty plastic, labelled, and transported to an approved asbestos disposal facility. It is illegal to dispose of asbestos in regular rubbish collections​.

    5. Final Inspection and Air Monitoring

    Once the asbestos has been removed, the area will be cleaned, and a visual inspection will be conducted by an independent and competent person, such as an asbestos hygienist or consultant. Airborne asbestos fibre tests  are required following the removal of friable asbestos-containing materials to ensure that no asbestos fibres remain in the air. Only after the area is declared safe and a clearance certificate for the works is issued can it be reoccupied by unprotected personnel.

    Why Professional Asbestos Removal is a Must

    Attempting to remove asbestos on your own can have severe consequences, including exposing yourself and others to harmful fibres and contaminating your home. In Australia, it is illegal for unlicensed individuals to remove more than 10 square metres of non-friable asbestos. Only licensed professionals can handle friable asbestos, which requires higher safety standards.

    Costs of Asbestos Removal in Australia

    The cost of asbestos removal in Australia varies based on several factors, including the size of the area to be treated and the type of asbestos involved. Here’s what influences the cost:

    • Size and extent:
      Larger projects typically cost more due to the amount of material that needs to be safely removed.
    • Type of asbestos:
      Friable asbestos is more hazardous and requires extra safety precautions, which can increase the cost.
    • Location:
      If the asbestos is in a hard-to-reach area, this could also affect the pricing.
