Asbestos in Demolition: Safety Measures and Legal Requirements in Sydney

When it comes to demolition projects in Sydney, one of the most critical considerations is the presence of asbestos. This hazardous material, once widely used in construction, poses significant health risks if not handled properly. In this comprehensive guide, we'll explore the safety measures and legal requirements surrounding asbestos in demolition projects in Sydney, ensuring you're well-informed for your next project.

Understanding Asbestos in Sydney Buildings

Asbestos was commonly used in Australian buildings until the late 1980s, with a total ban on its use implemented in 2003. In Sydney, many older buildings still contain asbestos in various forms, including:

  • Roofing and guttering
  • Wall cladding
  • Insulation
  • Floor tiles
  • Pipe lagging
  • Electrical switchboards

Understanding where asbestos might be present is crucial for any demolition project in Sydney, especially for buildings constructed before 1990.

Health Risks Associated with Asbestos

Asbestos poses severe health risks when its fibers become airborne and are inhaled. Exposure to asbestos can lead to serious diseases, including:

  • Asbestosis (scarring of lung tissue)
  • Lung cancer
  • Mesothelioma (cancer of the lining of the lungs, chest, or abdomen)
  • Pleural plaques (thickening of the lung lining)

These health risks underscore the importance of proper handling and removal of asbestos during demolition projects in Sydney.

Sydney has strict regulations governing asbestos removal during demolition. Key legal requirements include:

  • Asbestos removal must be carried out by a licensed asbestos removalist.
  • For amounts greater than 10 square meters of non-friable asbestos or any amount of friable asbestos, only Class A licensed removalists can perform the work.
  • SafeWork NSW must be notified at least five days before asbestos removal work begins.
  • An asbestos removal control plan must be prepared before work commences.
  • Air monitoring may be required during and after removal.
  • A clearance inspection must be conducted after removal is complete.

Safety Measures for Asbestos Removal During Demolition

Ensuring safety during asbestos removal in demolition projects is paramount. Key safety measures include:

  • Use of appropriate Personal Protective Equipment (PPE), including respirators, disposable coveralls, and gloves.
  • Proper containment of the work area to prevent the spread of asbestos fibers.
  • Use of wet methods to minimise dust generation.
  • Proper decontamination procedures for workers and equipment.
  • Correct labeling and disposal of asbestos waste.
  • Regular air monitoring to ensure fiber levels remain below safe limits.

At Active Demolition, we strictly adhere to these safety measures in all our asbestos removal and demolition projects.

Identifying Asbestos Before Demolition

Before any demolition work begins, it's crucial to identify the presence of asbestos. This typically involves:

  1. Asbestos Audit: A thorough inspection of the property by a licensed asbestos assessor.
  2. Sample Testing: Suspected materials are sampled and tested in a NATA-accredited laboratory.
  3. Asbestos Register: Creation or updating of an asbestos register for the property.
  4. Management Plan: Development of an asbestos management plan if asbestos is to be left in situ.

For more information on asbestos identification, you can refer to the Asbestos Awareness website.

The Asbestos Removal Process

The asbestos removal process during demolition typically involves the following steps:

  1. Site Preparation: Setting up containment areas, decontamination units, and warning signs.
  2. Removal: Carefully removing asbestos-containing materials using appropriate techniques to minimise fiber release.
  3. Decontamination: Thorough cleaning of the area and proper decontamination of workers and equipment.
  4. Waste Packaging: Double-bagging or wrapping asbestos waste in heavy-duty plastic.
  5. Clearance Inspection: A licensed assessor conducts a visual inspection and air monitoring.
  6. Clearance Certificate: Issuing of a clearance certificate once the area is deemed safe.

Our asbestos removal services at Active Demolition follow this rigorous process to ensure safety and compliance.

Proper Disposal of Asbestos Waste

Proper disposal of asbestos waste is critical to prevent environmental contamination and public health risks. In Sydney, asbestos waste must be:

  • Double-wrapped in heavy-duty plastic (minimum 200μm thick) or sealed in heavy-duty plastic-lined containers.
  • Clearly labeled as containing asbestos.
  • Transported by a licensed waste transporter.
  • Disposed of at a landfill site licensed to accept asbestos waste.

Costs Associated with Asbestos Removal in Demolition

The cost of asbestos removal during demolition can vary significantly depending on several factors:

  • The amount and type of asbestos present
  • The location and accessibility of the asbestos
  • The complexity of the removal process
  • The need for air monitoring and clearance inspections
  • Disposal fees

While asbestos removal adds to the overall cost of demolition, it's a crucial investment in safety and legal compliance. For a detailed cost estimate for your specific project, contact us for a personalized quote.

Choosing the Right Asbestos Removal Contractor

Selecting a qualified and experienced asbestos removal contractor is crucial for the safety and success of your demolition project. Consider the following when choosing a contractor:

  • Proper licensing for asbestos removal work
  • Adequate insurance coverage
  • Experience in similar projects
  • Positive references and reviews
  • Clear communication and detailed quotes
  • Commitment to safety and regulatory compliance

At Active Demolition, we meet all these criteria and are committed to providing safe, compliant, and efficient asbestos removal services as part of our residential and commercial demolition projects in Sydney.

Frequently Asked Questions About Asbestos in Demolition

It's difficult to identify asbestos by sight alone. If your building was constructed before 1990, it's best to assume it contains asbestos unless proven otherwise. The only way to be certain is to have suspected materials tested by a NATA-accredited laboratory. At Active Demolition, we can arrange for professional asbestos inspections and testing as part of our demolition services.

In NSW, homeowners are legally allowed to remove up to 10 square meters of bonded (non-friable) asbestos. However, this is not recommended due to the health risks involved. For amounts greater than 10 square meters, or for any amount of friable asbestos, you must use a licensed asbestos removalist. For demolition projects, it's always best to use professional services to ensure safety and compliance with all regulations.

Friable asbestos is any material containing asbestos that can be easily crumbled or reduced to powder by hand pressure when dry. This type is more dangerous as it's more likely to release fibers into the air. Examples include pipe lagging and sprayed insulation.

Non-friable (or bonded) asbestos is mixed with other materials like cement or resin, making it more stable and less likely to release fibers unless damaged or deteriorated. Examples include asbestos cement sheeting and vinyl floor tiles. While less hazardous, non-friable asbestos still requires careful handling during demolition.

The duration of asbestos removal depends on various factors, including the amount and type of asbestos, the size of the property, and the complexity of the removal process. For a typical residential property, asbestos removal might take anywhere from a few days to a couple of weeks. Commercial or industrial properties may take longer. It's important to note that rushing asbestos removal can compromise safety, so a thorough job is always prioritised over speed.

If asbestos is discovered unexpectedly during demolition, all work must stop immediately. The area should be secured to prevent access, and a licensed asbestos assessor should be called to inspect the site. They will determine the extent of the asbestos presence and develop a management plan. Removal will then be carried out by a licensed asbestos removalist before demolition can continue. This situation underscores the importance of thorough pre-demolition asbestos audits to avoid delays and additional costs.

Air quality monitoring is a crucial part of asbestos removal. It typically involves:

  • Background monitoring before work begins to establish baseline fiber levels
  • Control monitoring during removal to ensure containment measures are effective
  • Clearance monitoring after removal to ensure the area is safe for re-occupation

Monitoring is carried out using specialised equipment that captures air samples. These samples are then analyzed in a laboratory to determine the concentration of asbestos fibers in the air. At Active Demolition, we work with certified occupational hygienists to ensure thorough and accurate air monitoring throughout the asbestos removal process.

Proper Personal Protective Equipment (PPE) is essential for safe asbestos removal. This typically includes:

  • Respiratory protective equipment (RPE) such as P2 or P3 rated masks or powered air-purifying respirators (PAPR)
  • Disposable coveralls with hood and boot covers
  • Gloves
  • Safety footwear
  • Eye protection

All PPE is disposed of as asbestos waste after use to prevent contamination. Our team at Active Demolition is thoroughly trained in the correct use and disposal of PPE for asbestos removal.

For safety reasons, it's generally recommended that you vacate the premises during asbestos removal. This is especially true for friable asbestos removal or large-scale removal projects. The specific requirements can vary depending on the extent and location of the asbestos, but your safety is paramount. Your asbestos removal contractor will advise you on the necessary precautions and whether you need to vacate the property. At Active Demolition, we always prioritise the safety of our clients and provide clear guidance on this matter.

Asbestos waste disposal in Sydney follows strict guidelines:

  1. The waste is wetted down to minimise fiber release.
  2. It's double-wrapped in heavy-duty plastic (at least 200μm thick) or sealed in heavy-duty plastic-lined containers.
  3. All packages are clearly labeled as containing asbestos.
  4. The waste is transported by a licensed waste transporter.
  5. It's disposed of at a landfill site specially licensed to accept asbestos waste.

Proper documentation, including waste transport certificates, is maintained throughout this process. At Active Demolition, we ensure all asbestos waste from our demolition projects is disposed of in full compliance with these regulations.

After asbestos removal, you should receive several important documents:

  • Asbestos Removal Control Plan: Outlines the specific procedures used for the removal
  • Asbestos Removal Completion Statement: Confirms that asbestos removal has been completed
  • Air Monitoring Results: Shows that fiber levels are below the safe threshold
  • Clearance Certificate: Issued by an independent licensed asbestos assessor, declaring the area safe for re-occupation
  • Waste Disposal Receipts: Proving that asbestos waste was disposed of at an authorized facility

These documents are important for your records and may be required if you sell the property in the future. At Active Demolition, we ensure all our clients receive comprehensive documentation following asbestos removal.
