Which statement best describes noncombustible construction?

• A. They use combustible materials for structural members
• B. They use noncombustible materials for structural members
• C. They avoid any metal components
• D. They rely on wooden framing only

Answer: (B)

Noncombustible construction centers on the materials used for the building’s structural parts. The statement that best describes it is that the structural members are made from noncombustible materials. This means load-bearing elements like beams, columns, floors, and roofs are built with materials such as concrete, masonry, or steel that do not ignite and contribute less to flame spread. Using combustible materials for structural members would compromise that fire-resistance goal, and relying on wooden framing would be an example of combustible construction rather than noncombustible. Excluding metal is not correct, because metal is commonly used in noncombustible construction and helps provide strength without being a fire source. In short, noncombustible construction emphasizes nonflammable materials for the core structural components.
