Which of the following materials is NOT typically used to build an asbestos work area?

When establishing an asbestos work area, the goal is to create a controlled environment that minimizes the risk of asbestos exposure. Common materials used in constructing these areas include plastic sheeting or poly, which is used to seal off the space and prevent the release of asbestos fibers into the air. Plastic tape is also essential for securing the seams and ensuring that the barriers are airtight. Decontamination (decon) units are integral to safely removing contaminants and protecting workers as they exit the work area.

In contrast, metal sheets are generally not used for building asbestos work areas because they do not provide the same level of containment as plastic materials. Metal does not conform easily to create airtight seals or barriers, and its use would not effectively control the spread of asbestos fibers. Thus, metal sheets do not serve the purpose of protecting the environment from contamination and would be less effective than the plastic materials and decon units that are standard in asbestos containment practices.
