What is the primary purpose of installing critical barriers before asbestos abatement?

The primary purpose of installing critical barriers before asbestos abatement is to prevent contamination of non-asbestos areas. Properly constructed critical barriers create a controlled environment that isolates the work area from the surrounding spaces, thereby minimizing the risk of asbestos fibers being released into other areas. This containment is vital for protecting the health and safety of workers and occupants, as asbestos exposure can lead to serious health issues. By ensuring that non-asbestos areas remain uncontaminated, the abatement process can proceed safely and effectively, adhering to regulatory standards and best practices in asbestos management.
