Which code would you expect for a building with exterior walls made of metal or other non-combustible material?

• A. Code 3
• B. Code 6
• C. Code 1
• D. Code 4

Answer: (A)

Construction materials and fire behavior drive risk classifications. When exterior walls are metal or otherwise noncombustible, the building offers less fuel to a fire on the exterior and typically has lower potential for flame spread along the outside. That reduced hazard is captured by the code category for noncombustible exterior construction. Among the options, the one that corresponds to noncombustible exterior walls matches this scenario best. The other codes would generally align with more combustible exterior materials or less protective exterior construction, which doesn’t fit the noncombustible shell described.
