Which statement is NOT a function of fire stopping assemblies?

• A. Sealing penetrations to maintain fire resistance.
• B. Sealing joints through fire-resistance-rated walls and floors.
• C. Providing decorative finishes.
• D. Preventing smoke migration.

Answer: (C)

Fire stopping assemblies are intended to restore and maintain the fire-resistance of walls and floors by sealing penetrations and joints, so flames, heat, and smoke cannot easily pass between compartments. This containment helps preserve the rated fire duration and limits smoke migration, which is crucial for occupant safety and compartmentalization.

Providing decorative finishes is not part of that purpose. Aesthetics do not influence the fire-resistance performance of the enclosure, so a statement about decorative finishes does not reflect a function of fire stopping.
