What is the primary purpose of establishing critical barriers in an asbestos work site?

The primary purpose of establishing critical barriers at an asbestos work site is to prevent asbestos fibers from escaping into the surrounding environment. Asbestos is a hazardous material, and when disturbed, microscopic fibers can become airborne and pose serious health risks to workers and the general public. Critical barriers, which can include plastic sheeting and enclosed containment zones, serve as a means of isolating the work area, thereby minimizing the risk of exposure to airborne asbestos fibers. This containment strategy is vital for maintaining safety standards and compliance with regulatory guidelines.

The focus of such barriers is to effectively seal off the contamination area from the outside environment, ensuring that any disturbed asbestos material is contained and does not pose a risk to individuals outside the work zone. By preventing the dispersion of asbestos fibers, critical barriers play an essential role in protecting health and safety during asbestos abatement procedures.
