Although these assemblies serve their respective purposes, the fire wall has a unique place in the passive fire protection arsenal; thus, when a fire wall is utilized in a building, the special requirements associated with fire walls need to be carefully studied and incorporated where applicable. If the projecting element does not include concealed spaces, the fire wall need only comply with the basic requirements for fire wall horizontal continuity when the wall behind and below the projecting element is constructed of 1-hour fire-resistive construction for a distance equal to the depth of the projecting element on each side of the fire wall. Each time a contractor adds or removes a cable, the contractor must remove and replace semipermanent materials such as caulk and mortar.
