Why Asbestos Could Be a Serious Issue for Home A&A Works
Home renovation works in Singapore, particularly addition and alteration, can totally transform both aesthetics and functionality. But for homes constructed before the 1990s, there is a possible silent killer hidden behind ceilings, walls, and flooring – asbestos. Previously commonly used for its fireproof and insulating qualities, asbestos is now known as a toxic substance whose disturbance during renovation will lead to disastrous health consequences.
Understanding What Asbestos Is
Asbestos is a natural mineral consisting of soft and flexible fibres. Although tough and resistant to heat, the fibres can be released into the air when asbestos-containing materials are cut, drilled, or damaged. Upon inhalation, the fibres have been associated with serious diseases, such as lung cancer, asbestosis, and mesothelioma. This implies that through home renovations or A&A activities, accidental exposure will have lasting health effects on residents and contractors alike.
Where Asbestos Can Be Found Inside Homes
Even though asbestos consumption has been prohibited in Singapore since 1989, it may be found in buildings constructed before then. It is found in roofing sheets, ceiling boards, wall panels, floor tiles, and insulation materials. Asbestos is also found in some properties in pipe lagging or near water tanks. Property owners contemplating renovation must know that these materials, if mishandled, release harmful fibres into the environment.
Why Renovation Increases the Risk
When a building is being structurally altered, particularly as part of A&A work, the existing materials are usually cut, broken up, or removed. Such work has the potential to disrupt asbestos-containing materials, releasing the fibres. Even slight disturbance can be harmful, since asbestos fibres are extremely small and can be suspended in the air for up to hours. If proper containment and safety procedures are not in place, the risk of exposure greatly increases.
Health Risks Associated With Asbestos
The primary risk of asbestos is exposure over the long term. Fibres, upon inhalation, can be trapped within lung tissue, leading to inflammation and scarring. Asbestos-related disease symptoms may not appear until many years after exposure, when discovery is challenging. Exposure in renovation for homeowners or home builders may pose risks even with short-term exposure, illustrating the need for rigorous handling protocols.
Safe Handling and Removal Practices
When asbestos is suspected in a residential dwelling, it is advisable to have professional testing done prior to commencement of work. Trained asbestos removal experts employ specialised tools and equipment and protective clothing to ensure safe containment and disposal of asbestos materials. In Singapore, removal and disposal have to meet regulation standards by the National Environment Agency (NEA) such that asbestos waste is channelled to authorised disposal sites.
Legal and Compliance Considerations
Asbestos renovation work in Singapore has strict regulations. Asbestos handling must be done by licensed contractors, and prior notification to the authorities is necessary before the work begins. Homeowners carrying out addition and alteration work should ensure that their contractors are trained and accredited for safe handling of asbestos, since noncompliance could lead to legal repercussions.
Minimising the Risk for Homeowners
Prior to commencing any renovation, particularly for old buildings, a professional asbestos survey needs to be done. Homeowners would also need to ensure that any contractors working with asbestos-containing materials are qualified. This not only safeguards health but also ensures against accidental spread in the home environment. After removal, follow-up testing of the air quality is advisable to confirm the space is safe for reoccupation.
Conclusion
Asbestos might not be employed in contemporary construction today, but it is a latent danger in numerous older buildings. When undertaking A&A works, asbestos-containing materials get disturbed, and dangerous fibres are released into the air, which is very harmful to health. Proper inspection, safe removal, and stern adherence to policies are necessary to safeguard workers and residents alike. If you are undertaking any addition and alteration work in an older house, ensure you use certified experts to provide safety at all stages.
