When preparing the work area, what is the correct order for covering with plastic?

The correct order for covering the work area with plastic is to start with the windows, then address the floor, and finally cover the walls. This sequence is important for several reasons related to safety and containment when working with asbestos.

Initially, covering the windows helps prevent any airborne fibers from escaping through openings while the primary work is being conducted. Since windows often have gaps or are more difficult to seal definitively after other surfaces have been covered, it's crucial to ensure they are addressed first.

Next, covering the floor is vital as it provides a clean and protected surface to work on, minimizing the risk of contamination and ensuring that any debris or asbestos particles that may fall during the project are contained and easily cleaned.

Finally, the walls are covered last. Once the windows and floor are secured, applying plastic to the walls creates a complete enclosure for the work area. This layered approach builds a stronger barrier, limiting potential exposure and ensuring that any asbestos fibers that are disturbed during the work will be contained within the covered area.

Thus, following this order enhances effective containment and protects both the workers and the environment from potential asbestos exposure.
