Which term defines the method that states the period of time a wall, floor, or other building component can withstand flames, smoke, and gases and remain structurally sound?

• A. Dose response
• B. Decommission
• C. Fire-resistance rating
• D. Designated route

Answer: (C)

Fire-resistance rating describes how long a wall, floor, or other building component can withstand flames, smoke, and gases while remaining structurally sound. This rating comes from standardized fire tests that expose the element to fire and determine the time it can maintain structural stability and enclosure integrity. The result is given in minutes or hours and guides code requirements for fire separation and safety of occupants.
