Understanding how asbestos removal methods are conducted is crucial for maintaining a safe and compliant workplace. Asbestos poses serious health risks, and proper removal techniques are necessary to protect workers and meet legal standards. By learning about these methods, businesses can ensure the safety of their employees and adhere to regulations, fostering a secure work environment.

What kinds of asbestos removal methods are there?

Removing asbestos safely requires strict adherence to safety protocols and regulations to minimise the risk of exposure to asbestos fibers.

Here are some key methods for removing asbestos safely:


This method involves covering asbestos-containing materials with a sealant to prevent the release of fibres. Encapsulation is often used for materials that are in good condition and not easily disturbed, such as asbestos-containing insulation or ceiling tiles.


Enclosure entails constructing a barrier around asbestos-containing materials to prevent fibre release. This method is suitable for larger areas or materials that cannot be easily removed, such as asbestos-containing pipe insulation or boiler insulation.

Enclosure with ventilation

Similar to enclosures, this method involves sealing off asbestos-containing materials but also includes the installation of ventilation systems to control airflow and prevent the accumulation of airborne fibres within the enclosed space.

Wet removal

Wet removal involves saturating asbestos-containing materials with water or a wetting agent before removal to minimise the release of fibres. This method is commonly used for materials such as asbestos-containing floor tiles or roofing materials.

Mechanical removal

Mechanical removal involves using specialised equipment, such as HEPA-filtered vacuums, scrapers, or saws, to carefully remove asbestos-containing materials. This method is suitable for materials that cannot be encapsulated or enclosed, such as asbestos-containing insulation or pipe lagging.

Abrasive blasting

Abrasive blasting involves using high-pressure air or water to remove asbestos-containing materials from surfaces. This method is typically used for the removal of asbestos-containing coatings or paints from walls, ceilings, or structural components.

Chemical stripping

Chemical stripping involves applying chemical agents to asbestos-containing materials to break down the adhesive or bonding agents holding them together. Once the materials are softened or dissolved, they can be removed more easily. This method is often used for the removal of asbestos-containing mastics, adhesives, or sealants.

Controlled demolition

In some cases, asbestos-containing materials may be removed through controlled demolition techniques, where structures or components are carefully dismantled or demolished to access and remove the asbestos. This method requires careful planning and coordination to minimise fibre release and ensure worker safety.

How are the responsibilities of asbestos removal delegated?

Ultimately, responsibility for asbestos removal rests on those who have control over the premises and those who have a duty to protect the health and safety of occupants and workers.

Here's a breakdown of who may be responsible in various situations:

  • Property Owners: Property owners are generally responsible for identifying and managing asbestos-containing materials in their buildings or structures. This includes conducting asbestos surveys to assess the presence and condition of ACMs, implementing asbestos management plans to minimise exposure risks, and arranging for the safe removal and disposal of ACMs when necessary.
  • Employers: Employers are responsible for ensuring the health and safety of their employees in the workplace, which includes managing asbestos risks. If asbestos-containing materials are present in a workplace, employers must conduct risk assessments, provide appropriate training and personal protective equipment to workers, and implement control measures to minimise exposure. This may involve arranging for asbestos removal by qualified professionals.
  • Occupiers or Tenants: In some cases, occupiers or tenants of commercial properties may also have responsibilities regarding asbestos management and removal. While property owners typically retain ultimate responsibility, occupiers or tenants may be responsible for notifying the property owner or landlord of any asbestos-related issues and cooperating with them to ensure compliance with regulations.
  • Qualified Asbestos Professionals: Asbestos removal should only be carried out by qualified and licensed professionals who have received proper training and certification in asbestos abatement techniques. These professionals are responsible for safely removing and disposing of asbestos-containing materials in accordance with applicable regulations and guidelines.

How can I ensure that asbestos is safely removed from my building?

Ensuring that asbestos is safely removed from your building involves several critical steps and considerations. Here's a comprehensive guide to help you navigate the process:

  • Hire Qualified Professionals: Engage licensed asbestos removal contractors who have the expertise, training, and experience to safely handle asbestos removal. Verify their credentials, including licences, certifications, and insurance coverage, to ensure compliance with regulatory requirements.
  • Conduct a Comprehensive Survey: Prior to removal, conduct a thorough asbestos survey of the building to identify the location, type, and condition of ACMs. Hire a qualified asbestos surveyor to perform the survey and provide detailed reports outlining the findings.
  • Develop a Removal Plan: Work with the asbestos removal contractor to develop a comprehensive removal plan tailored to the specific characteristics of your building and the identified ACMs. The plan should include detailed procedures for containment, removal, waste disposal, and clearance testing.
  • Establish Containment Measures: Implement effective containment measures to prevent the spread of asbestos fibres during removal activities. This may involve sealing off the work area with plastic sheeting, installing negative air pressure systems, and using air filtration devices to capture airborne fibres.
  • Utilise Safe Removal Techniques: Ensure that the removal contractor employs safe and approved removal techniques, such as wet methods, to minimise the release of asbestos fibres. Avoid methods that generate dust or debris, such as dry scraping or sanding.
  • Provide Personal Protective Equipment (PPE): Ensure that workers involved in the removal process are equipped with appropriate personal protective equipment (PPE), including respirators, coveralls, gloves, and eye protection. The removal contractor should enforce strict adherence to safety protocols to protect workers and building occupants.
  • Monitor Air Quality: Conduct air monitoring before, during, and after asbestos removal to assess airborne fibre levels and ensure compliance with safety standards. Use accredited asbestos consultants to perform air monitoring and obtain clearance certificates verifying that the removal area is safe for reoccupation.
  • Dispose of Waste Properly: Dispose of asbestos-containing materials in accordance with regulatory requirements and guidelines. Seal removed materials in double-bagged, labelled containers and transport them to licensed asbestos disposal sites for proper disposal.
  • Document the Removal Process: Maintain detailed records of the asbestos removal process, including work plans, air monitoring results, waste disposal manifests, and clearance certificates. Documentation provides accountability, regulatory compliance, and a valuable reference for future needs.
  • Follow Up with Maintenance: After removal, implement regular maintenance and monitoring measures to ensure that the building remains free from asbestos contamination. Conduct periodic inspections and air monitoring to detect any potential issues and address them promptly.

What are the consequences of not removing asbestos properly?

The consequences of not removing asbestos properly can have far-reaching impacts on public health, safety, environmental quality, and legal compliance. More specifically, these consequences include;

  • Health Risks: Asbestos exposure can lead to various health problems, including respiratory issues, lung diseases, and certain types of cancer such as mesothelioma and lung cancer. Inhalation of asbestos fibres can cause scarring of the lungs (asbestosis) and increase the risk of developing serious and often fatal diseases over time. Improper removal techniques can release asbestos fibres into the air, increasing the likelihood of exposure and associated health risks.
  • Occupational Safety Violations: Failure to comply with occupational safety regulations and guidelines for asbestos removal can result in violations and penalties from regulatory agencies such as Safe Work Australia. Violations may include inadequate training, lack of proper PPE, failure to establish containment measures, and improper disposal of asbestos-containing materials. Penalties for non-compliance can include fines, citations, and legal sanctions.
  • Environmental Contamination: Improper asbestos removal practices can lead to environmental contamination, as asbestos fibres released into the air or water can spread to surrounding areas and pose risks to public health and ecosystems. Contaminated soil, waterways, and air can have long-term environmental consequences and may require costly remediation efforts to fix.
  • Legal Liability: Property owners, employers, contractors, and other parties involved in asbestos removal may face legal liability for negligence, negligence per se, or violations of environmental and occupational safety laws. Legal claims and lawsuits related to asbestos exposure can result in significant financial costs, damages, and reputational harm.
