Fire walls can be constructed as: A freestanding. C bearing. B non-rated walls. D exterior walls.

• A. Freestanding
• B. Exterior walls
• C. Bearing
• D. Non-rated walls

Answer: (A)

Fire walls are meant to be self-contained barriers that separate different parts of a building and resist fire for a specified time. The important property is that they stand on their own—freestanding—carrying their own load and remaining stable from the foundation up through the roof without relying on surrounding structure to stay in place. This self-supporting, continuous wall ensures the fire remains contained and life safety is preserved even if adjacent elements are compromised.

Exterior walls are part of the building envelope and not primarily designed as interior fire barriers. A wall can be load-bearing, but that describes its structural role, not its fire-separation function. Non-rated walls do not meet fire-resistance requirements. So, the freestanding option best reflects how fire walls are intended to function.
