Type I construction requires structural members to be made of which types of materials?

1. Combustible or limited combustible

2. Noncombustible or combustible

3. Noncombustible or limited combustible

4. Limited combustible or fire-resistant

The correct answer is: Noncombustible or limited combustible

Type I construction requires structural members to be composed exclusively of noncombustible or limited combustible materials. This construction type is designed to maximize fire resistance, allowing it to withstand high temperatures without significant structural failure. Noncombustible materials, such as steel, concrete, and masonry, do not ignite or contribute to the fire load. Limited combustible materials, which may ignite under certain conditions but are still less likely to contribute significantly to fire spread, offer an additional layer of safety. This high fire resistance is critical in buildings classified as Type I, especially in high-rise structures, where evacuation can be challenging, and the potential for fire spread needs to be minimized. Properly understanding the classification of materials and their fire resistance properties is essential for ensuring compliance with building codes and for implementing effective fire safety measures.
