![]() Heat, smoke, and flames can quickly progress through these openings, spreading the fire into compartments that might otherwise have been protected. However, the protection provided by fire walls can be reduced or eliminated when owners and contractors make unprotected penetrations through these walls for pipes, wires, and ducts. Fire walls are used to limit fire spread through structures such as multifamily apart- ments. Reinforced concrete, precast concrete, and protected steel frame construction meet the criteria for Type I construction. ![]() Type I construction can be expected to remain structurally stable during a fire, and it is considered to be the most collapse resistant. Structural components such as walls, floors, and ceilings must be able to resist fire for a period of 3 to 4 hours depending on the component. All structural members are composed of noncombustible or limited-combustible ma- terials with a high fire-resistive rating. Type I construction (also known as fire-resistive construction) provides the highest level of protection from fire development and spread as well as collapse (Figure 4.16).
