True or False: The risk of failure for temporary seals installed on HVAC openings is generally higher during depressurization.

The statement is true because during depressurization, the pressure differential can exert greater forces on temporary seals covering HVAC openings. When a building is depressurized, air is being pulled out of the interior space, which creates a negative pressure relative to the outside environment. This negative pressure can cause temporary seals to be more vulnerable to failure, as the outward force acting on the seal can exceed its holding capacity.

Temporary sealing materials may not adhere as effectively or may be less robust compared to permanent solutions, leading to a higher risk of leaks if they are not properly managed. This context helps to understand why the risk of failure increases in a depressurized state compared to other scenarios where the pressure differential is less significant.
