- Tank insulation: Asbestos insulation was used to insulate tanks, pipes, and other industrial equipment, and any disturbance to these materials should be done by trained specialists following safety protocols.
- Adhesives: Asbestos was added to certain adhesives, like floor tile mastic and roofing adhesives, to enhance their strength and bonding properties, and using asbestos-free alternatives is now strongly recommended.
- Acoustical finishes: Asbestos was used in acoustical materials like ceiling tiles and panels to improve sound absorption, and intact asbestos-containing finishes should be managed carefully to prevent fibre release.
- Gaskets: Asbestos gaskets were widely used in various applications, including engines, pumps, and industrial machinery, and proper handling and disposal are necessary to prevent exposure.
- Fume hood liners: Asbestos-containing materials were used in laboratory fume hoods and exhaust systems for their fire-resistant properties, and laboratories should have these materials assessed and, if necessary, replaced with safer alternatives.
- Plaster: Asbestos was incorporated into some types of plaster for walls and ceilings, particularly in older buildings, and any renovation work involving asbestos-containing plaster must be conducted by professionals following safety guidelines.
- Pipe insulation: Asbestos insulation was commonly applied around pipes to provide thermal protection, and damaged or deteriorating insulation should be carefully removed to prevent asbestos fibre release.
- HVAC duct wrap: Asbestos-containing materials were used to insulate heating, ventilation, and air conditioning (HVAC) ductwork, and proper maintenance and monitoring are crucial to prevent potential exposure.
- Lab countertops: Some laboratory countertops were made with asbestos materials, particularly in older labs, and it is essential to verify and replace asbestos-containing countertops in laboratories for safety.
- Roofing: Asbestos was used in roofing materials, such as shingles and corrugated sheets, for its fire resistance and durability, and any repair or removal of asbestos-containing roofing should be performed by professionals.
- Pipe fittings: Asbestos-containing materials were used in pipe fittings like elbows and couplings, and when dealing with older systems, precautions must be taken to avoid disturbing these materials.
- Fire doors: Asbestos was used in the core of fire doors to enhance their fire resistance, and regular inspection and maintenance are necessary to ensure the safety of such doors.
- Chalkboard glue: Some older chalkboards were affixed to walls using glue that contained asbestos fibres, and any chalkboards suspected to have asbestos-containing glue should be handled by professionals during removal or renovation.
- Siding shingles: Asbestos-containing siding shingles were used in the past for their weather resistance and durability, and homeowners should consider having them checked and, if necessary, replaced with safer materials.
The effects of improper asbestos management
On environmental health
Improper asbestos management can severely harm environmental health. When asbestos-containing materials are mishandled, microscopic asbestos fibres can be released into the environment. These fibres, which are resistant to degradation, can contaminate soil and water bodies, posing long-term ecological threats.
The presence of asbestos fibres in the soil can disrupt the balance of microorganisms that are essential for nutrient cycling, impacting soil fertility and plant growth. Moreover, asbestos-contaminated soil can produce dust that carries these fibres back into the air, creating an ongoing source of exposure.
In the case of water contamination, asbestos fibres can infiltrate underground water sources and aquatic ecosystems. This pollution can impact the health of aquatic species and disrupt food chains, ultimately affecting biodiversity. Furthermore, if these contaminated water sources are used for irrigation, asbestos can enter the food chain, posing risks to wildlife and potentially humans.
In essence, the environmental impact of improper asbestos management is vast and far-reaching, highlighting the necessity for rigorous control measures and safe disposal practices. Environmental exposure to asbestos can harm wildlife and ecosystems by disrupting natural processes and causing genetic mutations in organisms.
On human health
Improper asbestos management can have grave consequences for human health. When asbestos-containing materials are not handled correctly, tiny asbestos fibres can become airborne and easily inhaled by individuals. Prolonged exposure to these hazardous fibres can lead to serious health conditions. Asbestos exposure is a major occupational hazard for workers involved in industries like construction, ship building and mining.
One of the most significant health risks associated with asbestos exposure is the development of lung diseases, such as asbestosis and mesothelioma. Asbestosis is a progressive lung disease that can cause severe scarring of the lung tissue, leading to breathing difficulties and reduced lung function. Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, heart, or abdomen, and it is almost exclusively caused by asbestos exposure.
Aside from these major diseases, asbestos exposure is also linked to lung cancer, particularly in individuals who smoke. The combination of smoking and asbestos exposure greatly amplifies the risk of lung cancer.
Moreover, asbestos fibres can remain dormant in the body for many years before health issues manifest. This long latency period makes early detection and prevention all the more crucial.
How can I best manage asbestos to avoid these harmful effects?
By adhering to the following best practices and taking asbestos management seriously, you can minimise the risk of harmful effects on both human health and the environment:
Identify and assess
First and foremost, conduct a thorough inspection to identify any asbestos-containing materials in your surroundings. This includes checking older buildings and structures that might have used asbestos in construction. Engaging certified professionals to assess the condition of these materials is crucial, as they can determine the risk of exposure and recommend appropriate management strategies.
Follow regulations and guidelines
Familiarise yourself with both local and national regulations regarding asbestos management. Compliance with these regulations is paramount for the safe handling, removal, and disposal of asbestos-containing materials. Ignoring or neglecting these guidelines can not only lead to legal issues but also endanger the health of yourself and others.
Engage certified professionals
It cannot be stressed enough that asbestos management should never be a DIY task. Always hire certified and experienced professionals for asbestos removal and handling. These experts possess the specialised knowledge, training, and equipment necessary to effectively minimise fibre release and ensure a safe and controlled environment during the process.
Use protective gear
Whenever you or professionals are dealing with asbestos, never compromise on personal protective equipment (PPE). Wear appropriate gear, such as high-quality respirators, disposable coveralls, gloves, and shoe covers. This will provide a crucial layer of protection, reducing the risk of inhaling airborne fibres and preventing skin contact.
Work in controlled areas
To prevent the inadvertent spread of asbestos fibres to other parts of the building or environment, enclose the work area completely. Employing negative air pressure and using plastic sheeting, along with airlock systems, will help maintain control and contain any potential release of asbestos.
Safe removal techniques
Opt for safe removal techniques that minimise fibre release. Wetting asbestos-containing materials before removal reduces the amount of dust generated. Additionally, choose hand tools over power tools and avoid abrasive actions that could disturb the material and release fibres.
After the removal process, ensure that asbestos waste is properly disposed of. Package the waste securely in leak-tight containers that are clearly labelled as asbestos materials. Follow local regulations for the transportation and disposal of asbestos waste at authorised waste facilities.
Educate and train
It's not just about personal safety; everyone involved in asbestos management must be adequately educated and trained. Provide thorough training on asbestos safety protocols to anyone who may come into contact with asbestos, including workers and occupants. This knowledge ensures that everyone is aware of the risks and knows how to handle asbestos-containing materials responsibly.
Monitor air quality
During asbestos removal, regularly monitor the air quality in the work area using appropriate instruments. This continuous monitoring helps verify that fibre levels remain within safe limits and allows for prompt action if any issues arise.
Renovation and demolition plans
Before initiating any renovation or demolition projects in older buildings, conduct comprehensive asbestos surveys. Taking this precautionary step will help identify potential asbestos-containing materials and enable the development of safe plans for handling and removing these materials, thereby reducing the risk of accidental exposure.
In addition to implementing safety measures, it's essential to raise awareness about the risks of asbestos exposure and the importance of proper management. Educate others about the potential dangers associated with asbestos and its safe handling. A well-informed community can contribute to the prevention of accidents and protect the health of individuals and the environment.
