What are the four basic approaches to asbestos abatement?

The correct answer identifies the four basic approaches to asbestos abatement as removal, encapsulation, enclosure, and a management plan.

Removal refers to the complete eradication of asbestos-containing materials (ACMs) from a building or area. This method is often considered the most effective way to eliminate any risk associated with asbestos exposure.

Encapsulation involves coating ACMs with a sealant that binds the fibers and prevents them from becoming airborne, providing a temporary remedy to minimize exposure risk.

Enclosure is the approach of containing the asbestos by constructing a physical barrier around it, thereby limiting the potential for fiber release into the air.

Lastly, having a management plan is essential for the ongoing maintenance and oversight of the condition of any remaining asbestos, ensuring that any potential hazards are monitored and managed effectively.

Each of these approaches serves a distinct purpose in managing asbestos risks and ensuring safety within impacted environments.
