What should be verified after completing the installation of firestop systems?

Verifying that all penetrations are fully sealed after the installation of firestop systems is crucial for ensuring the effectiveness of the firestop. Firestop systems are designed to prevent the spread of fire, smoke, and harmful gases through openings and penetrations in fire-rated walls, floors, and ceilings. If any penetrations are not fully sealed, it compromises the integrity of the fire barrier, potentially allowing fire and smoke to spread, which could endanger lives and property.

Sealing all penetrations ensures that the firestop system functions as intended and maintains the fire resistance rating of the assembly. This verification step is essential for compliance with safety standards and codes, as well as for the overall safety of the building occupants. A thorough inspection ensures that the materials used have been applied properly and that there are no gaps or weaknesses in the firestop application.

Other considerations such as ensuring a clean work area, checking for tools left behind, or maintaining color coding may be important for job site management or aesthetic purposes, but they do not directly impact the firestop system's ability to perform its life-saving function.
