Home renovations offer a chance to update and improve living spaces, but they also come with hidden risks, especially if your home was built before 1987. One of the most significant concerns is asbestos, a material once widely used for its fire resistance and insulating properties. Understanding how to identify and handle asbestos is crucial to ensuring a safe renovation process.
Understanding Asbestos and Its Types
Asbestos is a group of naturally occurring minerals that were commonly used in construction due to their strength and heat resistance. There are two primary types of asbestos that you should be aware of: friable and non-friable.
Friable Asbestos: This type contains up to 100% asbestos and is soft and crumbly. It’s more likely to release dangerous asbestos fibers into the air when disturbed. Friable asbestos was primarily used in industrial and commercial settings for insulation, including in ceiling spaces of homes.
Non-Friable Asbestos: Also known as bonded asbestos, this type is mixed with other materials, such as cement, which helps to bind the asbestos fibers and prevent them from becoming airborne. Common examples include asbestos cement sheeting, wall and floor tiles, and backing adhesives. While non-friable asbestos is less hazardous, it can still pose risks if it becomes damaged or deteriorates.
Common Locations of Asbestos in Older Homes
Asbestos can be found in various parts of older homes. Knowing where to look can help you take appropriate precautions.
- Exterior Cladding and Eaves: Many homes built before 1987 feature asbestos sheeting as cladding or in the eaves. Look for flat or corrugated sheets, often used for roofing, wall linings, and exterior cladding. Although these materials may appear harmless, if they are damaged or deteriorating, they can pose a risk. Asbestos removal should be considered if these materials are in poor condition.
- Roofing and Fences: Corrugated asbestos sheeting was commonly used for roofing and fences. If you find this material in your home, especially if it’s corroded, it’s essential to engage a professional for asbestos removal to prevent the release of harmful fibers.
- Electrical Switchboards and Insulation: Asbestos was used in older electrical switchboards and as insulation around fuses. Although less visible, these areas can be a source of asbestos if they contain damaged or deteriorated materials.
- Concrete Paths and Driveways: Surprisingly, asbestos was sometimes mixed into concrete paths and driveways as a filler. If you plan to remove or renovate these surfaces, be cautious. Jackhammering or breaking up these materials can release asbestos fibers into the air.
- Interiors: Inside the home, asbestos may be present in wall and ceiling materials, including old ceiling tiles, wallpaper backing, and underlay for carpets. These materials can be found in rooms like kitchens and bathrooms, where asbestos was often used in wet areas.
Safe Handling and Removal of Asbestos
When dealing with asbestos, the primary goal is to prevent fiber release into the air, which can be harmful when inhaled. Here are steps to handle and manage asbestos safely:
- Inspection and Testing: Before beginning any renovation, have your property inspected by a professional to identify the presence of asbestos. An inspection report will detail where asbestos is located and its condition. If asbestos is found, testing samples in a certified laboratory can confirm its type and risk level.
- Professional Asbestos Removal: If you discover asbestos materials that are damaged or if you’re planning significant renovations, it’s crucial to hire licensed asbestos removal professionals. They have the expertise and equipment to safely remove and dispose of asbestos materials without risking exposure.
- Avoid DIY Removal: DIY removal of asbestos is highly discouraged. Disturbing asbestos-containing materials can release harmful fibers into the air. If you suspect asbestos, treat it with caution and contact professionals for removal.
- Sealing and Painting: If asbestos materials are in good condition and you prefer not to remove them, sealing and painting can help contain the asbestos fibers and prevent them from becoming airborne. However, this is a temporary measure and should be combined with regular inspections to monitor the condition of the materials.
- Handling and Disposal: If asbestos removal is necessary, ensure that all asbestos-containing materials are carefully handled and disposed of according to local regulations. Water blasting or sanding asbestos is particularly dangerous as it can make the fibers airborne, increasing health risks.
Health Risks and Precautions
Asbestos exposure is linked to severe health issues, including asbestosis, lung cancer, and mesothelioma. The risks arise when asbestos fibers are inhaled, leading to long-term health problems. Renovators and homeowners are particularly at risk, especially if they are involved in DIY projects without proper precautions.
According to recent studies, a significant number of DIY renovators report asbestos exposure during home renovations. It’s crucial to take these risks seriously and implement proper safety measures to protect yourself and your family.
Conclusion
Renovating an older home requires careful consideration, especially when it comes to handling asbestos. By understanding where asbestos might be found, how to safely manage it, and the importance of professional asbestos removal, you can undertake your renovation projects with confidence and ensure a safer living environment. Always remember to seek professional advice and services when dealing with asbestos to avoid unnecessary health risks and ensure compliance with safety regulations.
