Asbestos was once a common material used in the construction of homes and buildings in Australia. It was used in various ways, and materials containing asbestos are known as asbestos containing materials.
Asbestos containing materials are concerning due to serious health risks and strict regulations. This article will cover what ACMs are, where they are found, their dangers, safe handling, and removal costs.
Asbestos-containing materials (ACMs) have a storied history in construction due to their remarkable properties. These materials were widely used for their fire resistance and durability, making them a staple in building construction from the 1940s to the late 1980s. ACMs were often mixed with cement or other bonding agents, enhancing their strength and versatility. This blending process allowed asbestos to be used in various forms, including asbestos cement sheeting and low-density boards (LDB).
One of the most common applications of ACMs was in asbestos cement sheeting, which provided a robust solution for roofing and wall sheeting in both domestic and commercial buildings. These materials, which contain up to 70% asbestos fibres, were not only durable but also resistant to:
This made them highly valued in houses built for construction.
The use of asbestos simply became ubiquitous in building materials, leading to its presence in many structures still standing today. Preventing the release of asbestos fibres, which pose significant health risks, hinges on proper identification and management of these materials related to asbestos use.
Asbestos is commonly found in numerous areas within homes and buildings, particularly those constructed before the 1990s. Some common locations where asbestos might be lurking include:
These materials, once integral to building safety and durability, now pose hidden dangers that many homeowners may be unaware of, as do other materials.
Internally, non-friable asbestos materials were often used in ‘wet’ areas such as kitchens, bathrooms, and laundries, where they served as wall sheeting or ceiling panels. Externally, asbestos cement sheeting and other non-friable asbestos products, including asbestos sheeting, were commonly used for roof sheeting, guttering, gables, eaves, and cladding. These materials, while sturdy, can become hazardous if damaged and disturbed.
Moreover, friable asbestos products, which can be easily crumbled and release asbestos fibres into the air, might be found in older domestic heaters, stoves, and even some types of insulation. Familiarity with these common locations aids in pinpointing potential asbestos hazards and implementing steps to mitigate risks.
Exposure to asbestos fibres is a serious health risk that can lead to deadly diseases. Mesothelioma and lung cancer are two of the most severe conditions caused by inhaling these microscopic fibres. The risk increases dramatically for smokers, as the combination of smoking and asbestos exposure significantly heightens the likelihood of lung cancer.
One of the most insidious aspects of asbestos-related diseases is their latency period. Symptoms often do not appear until 20 to 30 years after the initial exposure. This long delay makes early detection challenging and underscores the importance of minimizing exposure from the outset. Even a single heavy exposure can lead to serious health issues, although repeated exposure over time is more commonly the cause.
There is no known safe level of asbestos exposure. Breathing in asbestos fibres can damage lung tissue, leading to chronic lung diseases and other severe health conditions. Therefore, it’s paramount for individuals to comprehend the risks and implement all necessary precautions to evade exposure.
Identifying asbestos-containing materials (ACMs) is not something that can be done by sight (without extensive experience or knowledge) or smell. It requires the expertise of a licensed asbestos assessor who can conduct proper asbestos testing. These professionals typically collect samples and send them to accredited labs for analysis to confirm the presence of asbestos fibres in the materials.
Asbestos has no taste or smell, and trying to identify it by such means can be extremely dangerous. Some building materials may have warning labels indicating asbestos content, but the absence of a label does not guarantee that the material is asbestos-free. Therefore, relying on professional testing is the safest approach.
Low density boards (LDB) and other ACMs can only be accurately identified through this thorough and scientific process. Having suspected materials tested by licensed professionals aids in circumventing unnecessary exposure and preserving health.
Comprehending the distinction between non-friable and friable asbestos is integral to risk assessment. Non-friable asbestos is bonded with materials such as cement, making it solid and rigid. This type of asbestos is considered lower risk because it cannot be easily crumbled by hand, thus reducing the likelihood of fibre release.
In contrast, friable asbestos is highly hazardous because it can be easily crumbled, pulverized, or reduced to a powder by hand pressure. This makes it much more likely to release asbestos fibres into the air, posing significant health risks. Friable asbestos can be found in materials like insulation around hot water pipes, asbestos rope, and loose-fill asbestos.
Common examples of non-friable asbestos include asbestos cement sheeting and vinyl asbestos floor tiles. Acknowledging these differences aids in the safe and effective management of asbestos, guaranteeing the adoption of the correct precautions based on the type of asbestos present.
When dealing with asbestos, safety should always be the top priority. Wearing appropriate personal protective equipment (PPE) is essential to minimize exposure to harmful fibres and prevent actions that could release asbestos fibres. This includes items like disposable coveralls, gloves, and respiratory protection. Proper removal and disposal of PPE are equally important to prevent contamination.
Isolating the work area is another crucial step. Here are some ways to achieve this:
Using non-powered hand tools, such as hand saws or hand-powered drills, reduces the generation of dust and minimises the risk of releasing asbestos fibres into the air. Wetting down materials before and during work can also help keep dust levels low. These precautions are instrumental in guaranteeing that asbestos is managed safely and efficiently.
Professional asbestos testing is a critical step before any renovation or demolition work. Licensed professionals use specialized techniques to conduct comprehensive site assessments, identifying potential ACMs and evaluating the associated risks. This process guarantees safety and legal adherence, protecting both health and property.
Sample collection and analysis are vital components of asbestos testing. Experts collect samples and use advanced technology to confirm the presence of asbestos in materials. This thorough analysis helps in determining the appropriate course of action for managing or removing asbestos.
The cost of professional asbestos testing typically ranges from $350 to $600, depending on the scope and complexity of the project. Investment in professional testing guarantees accuracy and assists in navigating through the legal requirements related to asbestos handling and removal.
The cost of asbestos removal can vary widely, as several factors influence these costs. These influencing factors include the size of the project, location, and the condition of the asbestos.
Additionally, the disposal of asbestos is governed by strict regulations, adding to the overall cost. Proper disposal is essential to avoid environmental contamination and legal repercussions. Investing in professional asbestos removal not only guarantees adherence to regulations but can also augment property value and structural stability.
Improper handling of asbestos can lead to severe legal consequences. Individuals can face penalties up to $10,000, with additional daily fines of up to $1,000 for continuing offences. Local governments have the authority to issue infringement notices for asbestos-related offences, providing a cost-effective method to enforce compliance.
Professional services in asbestos testing and removal offer several benefits, including:
By adhering to regulations and employing licensed professionals, individuals and organisations can take advantage of these benefits.
Identifying and managing asbestos-containing materials (ACMs) is a critical responsibility for homeowners, renovators, and anyone involved in building maintenance.
