Asbestos was once a common material used in construction due to its durability and resistance to heat. However, as research progressed, it became evident that asbestos poses serious health risks, including various cancers and chronic respiratory diseases. For this reason, it is vital to conduct asbestos inspections in older buildings to prevent harmful exposure.
In Australia, the necessity for asbestos management and proper removal is regulated by strict laws to protect both building occupants and workers involved in renovation or demolition processes.
Let’s get straight to the point
Asbestos, a once common material in construction, poses serious health risks, including cancers and respiratory diseases when its fibres are inhaled. Buildings, particularly those constructed before the 1980s, often contain asbestos.
Professional asbestos inspections are crucial to identifying and managing asbestos-containing materials (ACMs) to prevent exposure.
In Australia, strict regulations require asbestos management, including removal by licensed professionals and regular monitoring.
Proper asbestos management ensures legal compliance, protects health, and maintains property value. Always rely on certified inspectors and removalists for safe handling and disposal of asbestos.
What Is Asbestos?
Asbestos refers to a group of naturally occurring minerals that form thin, fibrous crystals. These minerals were used extensively in building materials for insulation, fireproofing, and other purposes throughout the 20th century.
Asbestos was valued for its fire-resistant properties and its ability to strengthen building components such as roofing, tiles, and cement sheets.
However, asbestos-containing materials (ACMs) are dangerous when disturbed. When damaged, asbestos fibres can become airborne and easily inhaled. Once inhaled, these fibres can accumulate in the lungs, causing inflammation, scarring, and serious diseases over time.
Thus, identifying asbestos in buildings, particularly those constructed before the 1980s, is essential for ensuring the safety of everyone involved.
Why Is Asbestos Inspection Necessary?
Conducting an asbestos inspection is crucial for a number of reasons, primarily for public health and safety. Without proper identification, ACMs can be unknowingly disturbed during renovations or maintenance, leading to the release of harmful asbestos fibres. Asbestos exposure is linked to diseases such as:
- Mesothelioma: A form of cancer affecting the lining of the lungs or abdomen.
- Asbestosis: A chronic lung disease caused by prolonged exposure to asbestos fibres.
- Lung Cancer: Increased risk, particularly in individuals who are also smokers.
- Other Cancers: Asbestos exposure has been linked to cancers of the larynx, ovary, and digestive system.
Health Risks of Asbestos
Exposure to asbestos can cause irreversible health conditions, often with long latency periods. Symptoms of asbestos-related diseases might not appear until 20 to 40 years after initial exposure, making early detection and prevention critical. When ACMs are identified through professional inspections, it allows for a safe plan to either manage or remove the materials, reducing the risk of exposure.
Types Of Asbestos
There are six types of asbestos that fall into two broad categories:
- Serpentine Asbestos: Includes chrysotile (white asbestos), which has curly fibres and was the most commonly used in construction.
- Amphibole Asbestos: Includes amosite (brown asbestos), crocidolite (blue asbestos), tremolite, actinolite, and anthophyllite, which have straight and needle-like fibres that pose a higher health risk when inhaled.
Chrysotile asbestos was widely used in products such as insulation and roofing sheets, while crocidolite was commonly found in steam engine insulation and pipe lagging.
How Can You Identify Asbestos?
It is difficult to identify asbestos by sight alone, which is why it is necessary to hire certified asbestos inspectors. These professionals use specialised equipment and techniques, such as Polarised Light Microscopy (PLM) and Transmission Electron Microscopy (TEM), to analyse samples and confirm the presence of asbestos.
Key locations where asbestos is commonly found in older buildings include:
- Roofing materials: Cement sheets, roof shingles, and bitumen-based products.
- Insulation: Pipe lagging, boiler insulation, and loose-fill insulation.
- Flooring: Vinyl floor tiles and adhesives.
- Ceiling materials: Textured coatings, like Artex.
How To Safely Manage Asbestos?
Once asbestos has been identified, it is crucial to develop a plan for its safe management or removal. Some options include:
- Encapsulation: This involves sealing the asbestos fibres to prevent them from becoming airborne.
- Removal: In cases where the asbestos is in poor condition or where renovation work will disturb it, professional removal is the safest course of action.
- Ongoing Monitoring: Asbestos-containing materials that are in good condition can be monitored over time to ensure they do not deteriorate.
Steps To Conduct Asbestos Inspection
If you suspect your building contains asbestos, follow these key steps:
- Hire a Certified Asbestos Inspector: Only qualified professionals should conduct asbestos inspections. They will examine the building for potential ACMs and collect samples for laboratory analysis.
- Perform an Asbestos Management Survey: This survey is designed to locate and assess any ACMs that may be present in a building, ensuring the materials remain undisturbed and in good condition.
- Analyse Samples: Collected samples are tested using PLM or TEM techniques to confirm the presence of asbestos.
- Develop an Asbestos Management Plan: If asbestos is detected, a comprehensive plan should be created to manage or remove the materials safely.
Legal Requirements For Asbestos Management
In Australia, there are strict legal requirements concerning asbestos management, particularly for workplaces. Work Health and Safety (WHS) regulations mandate that employers and building owners must ensure that any ACMs are safely managed and that workers are protected from exposure.
Key regulations include:
- Asbestos Management Plan: Must be developed for buildings containing ACMs, outlining how the materials will be handled and monitored.
- Training: Workers involved in maintenance or demolition must receive proper training on asbestos safety procedures.
- Licensed Removalists: Only licensed asbestos removalists are allowed to handle high-risk ACMs.
Failure to comply with these regulations can result in severe penalties, including fines and legal action.
How To Reduce Asbestos Exposure Risks
Reducing the risk of asbestos exposure requires careful planning and adherence to safety guidelines. Key strategies include:
- Do Not Disturb ACMs: Avoid drilling, cutting, or sanding materials that may contain asbestos.
- Regular Inspections: Conduct regular inspections of buildings to ensure that ACMs are not deteriorating.
- Professional Removal: Hire licensed professionals to remove asbestos if it poses a risk.
Benefits Of Professional Asbestos Inspections
Investing in professional asbestos inspections offers numerous benefits, including:
- Health Protection: Prevents exposure to hazardous fibres, protecting both building occupants and workers.
- Legal Compliance: Ensures that your building complies with Australian regulations regarding asbestos management.
- Risk Management: Identifying asbestos early allows you to manage risks effectively and avoid future issues.
- Property Value: Proper asbestos management can maintain or even enhance the value of a property by addressing potential health risks.
