The Comprehensive Checklist for Safe and Efficient Asbestos Removal

When it comes to asbestos removal, there’s no room for shortcuts. Asbestos is a notorious hazard, and handling it safely requires precision, planning, and a deep respect for the dangers involved. Whether you’re a property owner, facility manager, or construction professional, knowing how to properly remove asbestos is crucial—not just for compliance but for protecting lives.

Asbestos, once hailed for its durability and fire-resistant properties, is now known to pose significant health risks. Prolonged exposure to asbestos fibres can lead to severe illnesses, including lung cancer, asbestosis, and mesothelioma, a particularly aggressive form of cancer. These health risks make the safe removal and disposal of asbestos-containing materials (ACMs) an absolute necessity.

In this guide, we’ll walk you through a comprehensive checklist for asbestos removal, covering every step from preparation to post-removal procedures. Stick with us, and you’ll be ready to tackle your asbestos project safely and efficiently, ensuring that all legal requirements are met and that the health of everyone involved is protected.

Pre-Removal Preparation

Asbestos Survey and Risk Assessment

The first step in any asbestos removal project is identifying asbestos-containing materials (ACMs) within your building. This involves conducting a detailed asbestos survey, which a licensed asbestos assessor typically carries out. The survey will identify the location, type, and condition of any ACMs present, providing a comprehensive overview of the asbestos risks on site.

There are two main types of asbestos surveys: management surveys and refurbishment/demolition surveys. A management survey is designed to ensure that no one is harmed by the continuing presence of ACMs on the premises during normal occupancy. On the other hand, a refurbishment/demolition survey is necessary when the building (or part of it) is to be upgraded, refurbished, or demolished.

Once the ACMs are identified, a risk assessment must be performed. This assessment evaluates the state of the materials—whether they’re damaged, friable, or still intact. Friable asbestos, which is easily crumbled and more likely to release fibres into the air, presents a higher risk than non-friable asbestos, which is more stable. The risk level determines the urgency of removal and the precautions needed to handle the asbestos safely. It’s a critical part of the process, ensuring that you’re fully aware of what you’re dealing with and can plan the removal accordingly.

Legal and Regulatory Compliance

Navigating asbestos regulations can be tricky, but it’s non-negotiable. In Queensland, asbestos removal is governed by strict laws under the Work Health and Safety Regulation 2011. These regulations stipulate everything from the licensing of removalists to the notification procedures required before work begins.

Before any removal, ensure you have all the necessary permits and have notified the relevant authorities. For instance, in Queensland, you must notify Workplace Health and Safety Queensland (WHSQ) at least five days before starting work that involves the removal of more than 10 square metres of non-friable asbestos or any amount of friable asbestos. The licensed asbestos removalist must provide this notification.

Additionally, it’s crucial to adhere to the National Code of Practice for the Safe Removal of Asbestos, which outlines best practices for safely handling and removing asbestos. Compliance isn’t just about avoiding fines—it’s about ensuring that asbestos is handled in a way that minimises risks to health and the environment. Working with licensed professionals who understand these regulations inside and out is essential.

Hiring Qualified Professionals

Asbestos removal is not a job for the inexperienced. It’s a highly specialised task that requires trained and licensed professionals, like the team from Coastal Demolitions. In Queensland, only licensed asbestos removalists can legally remove more than 10 square metres of non-friable asbestos, and a licensed professional must remove all friable asbestos.

When selecting a contractor, check their credentials thoroughly—look for licences, insurance, and a proven track record in asbestos removal. You should also verify that the contractor has a current asbestos removal licence issued by WHSQ.

The right team will have experience with projects similar to yours and will be able to navigate the regulatory landscape smoothly. Their expertise is your assurance that the job will be done correctly without cutting corners. Qualified professionals will also be well-versed in using specialised equipment, following strict safety protocols, and managing asbestos waste in compliance with all relevant laws.

Setting Up the Work Area

Site Preparation and Containment

Once you’ve got the green light to proceed, it’s time to prepare the site. Proper site preparation is crucial to ensure the safety of workers and prevent asbestos fibres from spreading beyond the work area. Containment is key to preventing asbestos fibres from spreading beyond the work area. This typically involves sealing off the site with plastic sheeting, setting up air filtration systems, and marking the area with clear signage.

To effectively contain asbestos, the work area should be isolated from the rest of the building. This may involve setting up negative air pressure units to prevent contaminated air from escaping the enclosure. All windows, doors, and vents within the containment area should be sealed with plastic sheeting and duct tape.

Containment measures ensure that asbestos doesn’t contaminate other parts of the building. Only trained personnel should enter the work area, and strict protocols must be followed to maintain safety and prevent exposure. Additionally, clear warning signs should be posted around the perimeter of the containment area to alert others of the hazards.

Equipment and PPE

Equipping your team with the right tools and personal protective equipment (PPE) is critical. Essential PPE includes disposable coveralls, gloves, and full-face respirators fitted with P3 filters, which are designed to protect against airborne asbestos fibres. Workers should also wear rubber boots and ensure that their coveralls have tight seals around the wrists and ankles to prevent fibres from entering.

Your team will also need specialised equipment like HEPA-filtered vacuums, which are crucial for cleaning up asbestos dust. Wetting agents are also commonly used to suppress dust and reduce the risk of airborne fibres during removal. In some cases, specialised tools like glove bags—sealed plastic bags with built-in gloves—are used for handling asbestos-containing materials, especially when working in tight spaces or with friable asbestos.

All PPE must be used correctly and disposed of safely after each session to prevent contamination. Proper training in the use of this equipment is non-negotiable. Workers should be trained on how to properly don and doff PPE, as well as how to safely handle and dispose of contaminated materials.

Asbestos Removal Process

Safe Removal Techniques

Asbestos removal isn’t just about getting the material out—it’s about doing so without releasing fibres into the air. Different types of ACMs require different removal techniques. For example, wet methods are often used to keep dust down, while more fragile materials may need to be removed using specialised tools like glove bags.

Wet methods are typically employed to minimise the release of asbestos fibres. This involves spraying the asbestos-containing material with water mixed with a wetting agent before removal. The wet material is less likely to release fibres when disturbed. Careful handling is essential—ACMs should be removed intact whenever possible to avoid breaking them, which could release fibres.

Working slowly and carefully is key. The goal is to keep the asbestos intact as much as possible, avoiding any actions that could cause the material to crumble or release fibres. Removed materials must be immediately sealed in heavy-duty bags or containers designed specifically for asbestos waste.

After removal, the surfaces from which the asbestos was removed should be cleaned with a wet cloth or a HEPA vacuum. The containment area should remain sealed until clearance air monitoring confirms that it is safe to remove the containment.

Waste Management and Disposal

Asbestos waste management is as critical as the removal process itself. Once removed, asbestos must be double-bagged in labelled asbestos waste bags and sealed to prevent fibre release. These bags should be transported by a licensed waste carrier to an approved disposal facility.

It’s crucial to follow local regulations for waste disposal to the letter. For instance, in Queensland, asbestos waste must be disposed of at a landfill site licensed by the Department of Environment and Science (DES) to accept asbestos waste. Transporting asbestos waste without a waste transport certificate or to an unlicensed facility can result in significant fines.

Documentation of the disposal process should be kept on file as proof of compliance and to ensure that asbestos doesn’t pose a risk to the environment or public health after it leaves your site. This documentation should include waste transport certificates and landfill receipts.

Post-Removal Procedures

Decontamination and Cleaning

After removing the asbestos, the work area and equipment used during the process must be thoroughly decontaminated. This involves using HEPA-filtered vacuums and damp cloths to wipe down all surfaces, ensuring that no asbestos fibres remain.

Depending on the extent of contamination, tools and equipment should either be cleaned or disposed of as asbestos waste. Decontamination also extends to the workers themselves, who must follow strict protocols to ensure that no asbestos fibres are carried out of the containment area. This may involve showering in a decontamination unit set up adjacent to the work area.

The goal is to leave the area completely free of asbestos fibres, ensuring that no residual contamination poses a risk to anyone re-entering the space. Decontamination of the work area and personnel is a critical step in preventing the spread of asbestos and ensuring the safety of all involved.

Final Inspection and Air Monitoring

Before the area can be declared safe, a final inspection and air monitoring must be conducted. Clearance testing involves taking air samples and sending them to a laboratory to confirm that no asbestos fibres are present in the air. This step is critical for ensuring that the area is safe for reoccupation.

Clearance air monitoring should be performed by a licensed asbestos assessor who is independent of the removalist to ensure an unbiased assessment.

The air samples are analysed in a laboratory, and the area is only deemed safe if the fibre concentration is below the allowable limit.

In addition to air testing, a visual inspection should be performed to verify that all asbestos materials have been removed and that the site is clean. The licensed assessor will check for any remaining ACMs, dust, or debris. Only once these tests have confirmed that the area is safe should the containment be removed and normal activities resumed.

Documentation and Reporting

Record-Keeping Requirements

Keeping detailed records of the asbestos removal process is essential for regulatory compliance and future reference. Your documentation should include the initial asbestos survey, risk assessments, work plans, waste disposal records, and the results of the final clearance testing.

These records are important not only for legal compliance but also for providing transparency to property owners and stakeholders. They ensure that the removal was conducted safely and in accordance with all regulations, which is especially important for any future transactions or inspections. In Queensland, these records must be kept for a minimum of 5 years.

Additionally, it’s wise to keep a copy of all communications with regulatory bodies, as well as any notices or permits obtained during the project. This documentation can be invaluable in the event of a compliance audit or if any issues arise post-removal.

Communicating with Property Occupants

Effective communication with property occupants is crucial throughout the asbestos removal process. Before work begins, inform them about the presence of asbestos, the risks involved, and the steps being taken to ensure their safety. Clear communication helps alleviate concerns and ensures everyone understands the precautions being implemented.

Once the removal is complete, let occupants know that the area has been cleared and is safe to return to. Providing them with documentation of the removal process and clearance results can help reassure them that the work was done correctly and that their environment is now safe. If any follow-up actions are needed, such as regular monitoring or further inspections, this should also be communicated clearly.
