What is the correct order and gauge of the plastics used in the work area?

The correct understanding of plastic gauge and its application in a work area, especially concerning asbestos removal or abatement, is a critical aspect of ensuring safety and containment. The use of higher gauge plastic indicates a thicker, more durable barrier that is better suited for preventing the escape of asbestos fibers and protecting workers from exposure.

In the context of the correct answer, using 6mil plastic for the floor provides a robust and secure barrier to protect against damage and ensure that any potentially hazardous materials are contained. Using 4mil plastic for the wall is appropriate since walls typically do not require the same thickness as floors, where heavier equipment or foot traffic might cause wear and tear. This layered approach, with multiple instances of 6mil and 4mil, demonstrates a strategic choice to balance protection where it is most necessary (the floor) and apply sufficient protection on the wall, which is also crucial for containment.

This arrangement reflects essential practices in asbestos management, emphasizing not only compliance with safety regulations but also a functional approach to risk mitigation. By layering these materials effectively, the integrity of the containment area is upheld, thereby safeguarding workers and limiting any potential dispersal of asbestos fibers into the environment.
