What is the primary objective of firestop systems?

The primary objective of firestop systems is to prevent the spread of smoke and fire through openings in walls, floors, and other barriers that are part of a building's structure. These systems are designed to seal gaps and penetrations, which can occur due to utilities and other installations, effectively compartmentalizing the fire. This compartmentalization limits the movement of fire and smoke to adjacent areas, providing crucial time for occupants to evacuate and for firefighting efforts to be implemented. Firestop systems are critical for life safety, protecting property, and maintaining the overall effectiveness of fire-resistant assemblies.

Other options, while they may touch on aspects of building design or maintenance, do not address the central purpose of firestop systems, which is focused on fire prevention and safety. Enhancing the aesthetic appeal or supporting structural integrity are important but secondary to the primary goal of fire containment.
