If you are inspecting a 1-hour framed gypsum wall with a 2-hour UL System installed, what should you do?

When inspecting a 1-hour framed gypsum wall that has a 2-hour UL System installed, it is essential to check if the installed system is suitable for the wall. This step is critical because each fire-rated system is designed for specific applications and conditions, and the compatibility of the firestop system with the wall's rating needs to be confirmed to ensure compliance with building codes and safety standards.

The 2-hour UL System may offer more protection than required, but it's vital to verify the installation aligns with both the tested assembly and the wall's fire-resistance rating. The effectiveness of the firestop system relies on proper installation consistent with tested configurations, so proper evaluation dictates whether the system is compliant with regulations.

In this case, focusing on whether the installed firestop assembly is appropriate for the wall helps ensure that it functions correctly in a fire event, thereby preventing potential failures in fire containment and damaging repercussions.
