Which statement about Type I construction is true?

• A. Roofs are extremely difficult to penetrate
• B. Timbers provide for structural stability
• C. Ease of Ventilation
• D. Structural members have little or no fire resistance

Answer: (A)

Type I construction is fire-resistive, built with noncombustible materials and fire-rated structural elements to resist heat and maintain stability during a fire. Because of that, roof assemblies are designed to be highly resistant, making roof penetrations by heat or flames very difficult. Timber isn’t used for structural stability in Type I; timber falls under other construction types and wouldn’t provide the necessary fire resistance. Ventilation ease isn’t a defining feature of this construction type, and the structural members in Type I are designed to have substantial fire resistance, not little or none.
