Asbestos, a naturally occurring mineral was once a popular construction material due to its durability, fire resistance, and insulating properties. However, it has been discovered that asbestos exposure can lead to severe health problems, including a rare and aggressive form of cancer called mesothelioma. As a result, asbestos inspections have become essential to maintaining a safe environment in homes and buildings.
Mesothelioma is a rare form of cancer that affects the mesothelial cells lining the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma), or heart (pericardial mesothelioma). It is almost exclusively linked to asbestos exposure, with most cases resulting from inhaling asbestos fibres over an extended period.
The symptoms of mesothelioma often appear 20-50 years after the initial exposure, making it difficult to diagnose and treat in its early stages. Common symptoms include chest pain, shortness of breath, fatigue, and unexplained weight loss. There is currently no cure for mesothelioma, but treatments such as surgery, chemotherapy, and radiation therapy can help manage the disease and improve patients’ quality of life.
How Asbestos Exposure Leads to Mesothelioma
When asbestos-containing materials are disturbed or damaged, microscopic fibres can be released into the air. If inhaled, these fibres can become lodged in the lining of the lungs, abdomen, or heart, causing inflammation and scarring. Over time, this damage can lead to genetic mutations in the mesothelial cells, causing them to divide uncontrollably and form cancerous tumours.
Factors that can raise the risk of developing mesothelioma include
- Duration and intensity of exposure: The risk of developing mesothelioma increases with the amount and time of asbestos exposure.
- Type of asbestos: Certain types of asbestos, such as crocidolite (blue asbestos), are more likely to cause mesothelioma than others.
- Genetic predisposition: Some people may have a genetic predisposition that makes them more susceptible to developing mesothelioma after asbestos exposure.
- Smoking: While smoking does not directly cause mesothelioma, it can significantly increase the risk of developing asbestos-related lung cancer and may worsen the effects of asbestos exposure.
The Importance of Asbestos Inspections
Regular asbestos inspections prevents mesothelioma and other asbestos-related diseases. By identifying and managing asbestos-containing materials (ACMs) in homes and buildings, property owners can minimise the risk of exposure to occupants and visitors.
Asbestos inspections can help:
- Identify the presence and location of ACMs: A professional inspector can accurately determine if asbestos is present and where it is located within the property.
- Assess the condition of ACMs: Inspectors can evaluate the state of asbestos-containing materials and determine if they pose an immediate risk.
- Develop a management plan: If asbestos is found, a comprehensive management plan can be implemented to address any hazards and minimise the risk of exposure.
- Ensure compliance with regulations: Asbestos inspections help property owners comply with federal, state, and local regulations, reducing potential legal liability.
- Facilitate safe removal and disposal: A professional inspector can recommend a licensed abatement contractor to remove and dispose of asbestos materials safely.
What to Expect During an Asbestos Inspection
A typical asbestos inspection involves the following steps:
- Preliminary inspection: The inspector visually examines the property, looking for signs of asbestos-containing materials and any damage or deterioration.
- Sampling: If suspect materials are found, the inspector collects samples for laboratory analysis following strict safety protocols.
- Laboratory analysis: Samples are sent to an accredited laboratory for analysis using polarised light microscopy (PLM) or transmission electron microscopy (TEM) to determine the presence and concentration of asbestos fibres.
- Reporting: The inspector provides a detailed report outlining their findings, including the location and condition of any ACMs, the results of laboratory analysis, and recommendations for managing or removing the asbestos.
- Post-inspection consultation: The inspector may also offer advice on the next steps, such as developing an asbestos management plan or hiring a licensed abatement contractor to remove the asbestos.
The link between asbestos exposure and mesothelioma highlights the importance of regular asbestos inspections in homes and buildings. By identifying and managing asbestos-containing materials, property owners can reduce the risk of exposure and help prevent the devastating effects of mesothelioma and other asbestos-related diseases. A professional asbestos inspection is critical to ensuring a safe environment for occupants and visitors.
