What is now generally agreed to be the best way to treat undamaged asbestos in buildings?

The best way to treat undamaged asbestos in buildings is to seal or wrap it to prevent the release of fibers. This approach is preferred when the asbestos material is in good condition and not likely to be disturbed. By sealing or wrapping asbestos, it minimizes the risk of asbestos fibers being released into the air, which can pose health risks when inhaled.

Removing asbestos can be complicated, often leading to potential exposure during the process. Similarly, simply leaving it undisturbed and unsealed does not provide any proactive safety measures to prevent fiber release. Painting over asbestos may provide some initial encapsulation, but it is not a long-term solution and can be ineffective if the surface deteriorates over time. Therefore, sealing and wrapping is recognized as the most effective method to ensure safety while minimizing disruption.
