When constructing containment, what is the recommended procedure for installing poly sheeting?

The recommended procedure for installing poly sheeting when constructing containment is to install it independently for walls and ceilings. This method allows for a more flexible and effective containment system. By treating the walls and ceilings as separate components, you can ensure that the sheeting is secured properly according to the specific requirements of each surface, which helps prevent potential leaks or breaches in the containment area.

This separation also facilitates easier adjustments and repairs if needed, as any damage to either the walls or ceiling sheeting can be addressed without affecting the other. Additionally, independent installation can enhance the overall structural integrity of the containment, ensuring that it remains sealed and effective throughout the duration of the asbestos remediation process.

The other provided options would not offer the same level of efficiency or effectiveness in maintaining a secure containment area. For instance, beginning installation horizontally or using a specific adhesive for sealing could introduce complications depending on the unique dimensions of the space being worked in. Installing vertically for easy access may also compromise the integrity of the containment if not managed carefully. Thus, the independent installation approach is essential in creating a reliable and robust containment environment.
