Which term is a wall built to prevent fire from spreading between sections of a structure?

• A. Firestop System
• B. Fungi
• C. Fire Wall
• D. Hard Wall System

Answer: (C)

In building fire safety, a wall built to stop fire from crossing between sections is a fire wall. This vertical barrier is designed to resist heat and flames for a specified period (a fire-resistance rating) and to maintain its integrity long enough to keep compartments separate. By doing so, it slows or prevents the spread of fire and smoke, helping to protect occupants and allow more time for evacuation and firefighting. The term you’d use for sealing around openings in fire-rated assemblies to preserve that protection is firestop, not a wall itself, so the other options don’t fit. Fungi is unrelated, and a hard wall system isn’t the standard term for this fire-containment barrier.
