Asbestos fences, once a common sight in Perth backyards, now represent a significant health hazard if not handled correctly. Many older properties still have these fences, a relic of a time when the dangers of asbestos were not widely understood. Removing these fences requires specialized knowledge, equipment, and adherence to strict regulations to prevent the release of harmful asbestos fibers into the environment. This article will delve into the complexities of asbestos fence removal in Perth, covering everything from identification and regulations to the safe removal process and finding qualified professionals. Improper handling can lead to serious health risks, including mesothelioma, lung cancer, and asbestosis. Therefore, understanding the correct procedures and seeking expert assistance is paramount for protecting yourself, your family, and the wider community.
Identifying Asbestos Fences
Asbestos fences typically have a grey, fibrous appearance and may be brittle or cracked with age. The sheets are often corrugated or flat and may be held together by metal straps or fixings. A common brand of asbestos fencing is "Super Six". While visual identification can be a clue, the only definitive way to confirm the presence of asbestos is through laboratory testing. A small sample can be taken by a licensed asbestos assessor and sent to a NATA-accredited laboratory for analysis. This process will identify the type and concentration of asbestos present, which is crucial for determining the appropriate removal method. Never attempt to take a sample yourself without proper training and equipment, as this can release dangerous fibers.
Regulations and Permits in Perth
The removal of asbestos-containing materials in Perth is strictly regulated by the Department of Mines, Industry Regulation and Safety (DMIRS). Depending on the amount of asbestos to be removed, either a licensed asbestos removalist must be used or certain training requirements must be met. For more than 10 square meters of non-friable asbestos (bonded asbestos, such as that found in fencing), a Class B asbestos removal license is required. You must also notify DMIRS at least five days before the work begins, providing details of the removal project, the licensed removalist, and the disposal method. Failure to comply with these regulations can result in hefty fines and legal repercussions. Always check the credentials of any asbestos removalist to ensure they are properly licensed and insured.
The Asbestos Removal Process
The safe removal of an asbestos fence involves a meticulous step-by-step process to minimize the risk of fiber release. This typically includes:
- **Site Preparation:** The area around the fence is cordoned off with warning tape to prevent unauthorized access. Drop sheets are laid down to catch any debris.
- **Personal Protective Equipment (PPE):** Removalists wear full protective suits, respirators, and gloves to prevent inhalation and skin contact with asbestos fibers.
- **Wetting Down:** The fence sheets are thoroughly wetted down with a special solution containing a wetting agent. This helps to bind the fibers and prevent them from becoming airborne.
- **Careful Dismantling:** The sheets are carefully dismantled one by one, avoiding any breakage or crushing. Fixings are removed with hand tools to prevent vibration.
- **Wrapping and Sealing:** Each sheet is immediately wrapped in heavy-duty plastic sheeting and sealed with duct tape.
- **Disposal:** The wrapped asbestos waste is transported in a sealed vehicle to a licensed asbestos disposal facility.
- **Decontamination:** The work area is thoroughly cleaned using a HEPA vacuum cleaner to remove any remaining fibers. Air monitoring may be conducted to ensure the area is safe.
Finding Qualified Asbestos Removalists in Perth
Choosing the right asbestos removalist is crucial for ensuring the job is done safely and legally. When selecting a removalist, consider the following:
- **Licensing:** Verify that the company holds a current Class B asbestos removal license issued by DMIRS. Ask to see their license and check its validity online.
- **Experience:** Look for a company with a proven track record of successfully completing asbestos fence removal projects in Perth.
- **Insurance:** Ensure the company has adequate public liability and workers' compensation insurance.
- **References:** Ask for references from previous clients and contact them to inquire about their experience.
- **Quotation:** Obtain detailed written quotations from several companies, outlining the scope of work, the removal process, and the disposal method.
- **Safety Procedures:** Discuss the safety procedures the company will implement to protect your family and the surrounding environment.
Cost of Asbestos Fence Removal
The cost of asbestos fence removal in Perth can vary depending on several factors, including the length of the fence, the accessibility of the site, and the complexity of the removal process. Generally, you can expect to pay between $30 to $70 per linear meter. This cost typically includes inspection, asbestos testing, removal, wrapping, transportation, and disposal fees. It's essential to obtain multiple quotes from licensed removalists to compare prices and ensure you're getting a fair deal. Be wary of companies that offer significantly lower prices than others, as this could indicate they are cutting corners on safety or not disposing of the asbestos waste properly.
