What are the primary methods of asbestos abatement?

Enclosure, containment, and demolition
Removal, encapsulation, and/or enclosure
Isolation and storage
Recycling and incineration

The correct answer is: Removal, encapsulation, and/or enclosure

The primary methods of asbestos abatement include removal, encapsulation, and enclosure. Removal involves taking out asbestos-containing materials from buildings to eliminate any risk of exposure. This method is often preferred when the material is damaged or deteriorating, as it presents a higher risk of asbestos fibers being released into the air. Encapsulation is a method where the asbestos-containing material is treated with a sealant that binds the fibers together, preventing them from becoming airborne. This approach is typically used when the asbestos material is in good condition, allowing it to remain in place while effectively minimizing the risk of exposure. Enclosure involves building a barrier around the asbestos-containing material to prevent access and contain any potential asbestos fibers. This method can be beneficial when removal is impractical or not necessary. The other options do not encapsulate the main recognized methodologies for asbestos abatement. While containment and demolition may relate to asbestos projects, they do not specifically address the primary recognized approaches for ensuring the safe management of asbestos.
