(Table 706.4) <br />Openings shall be protected by assemblies having a 3 hour fire rating. (706.8 and Table 716.1(2)) <br />2-1 1/2 hour assemblies may be used. <br /> <br />Fire wall shall extend from the foundation to a termination point at least 30 inches above both <br />adjacent roofs. (706.6) See exceptions for alternate protection at roof. <br /> <br />See Section 706.6.1 for requirements when a fire wall separates buildings of different heights. <br /> <br />See Section 706.6.2 for requirements when a fire wall separates buildings with sloped roofs. <br />Each opening through a fire wall shall not exceed 156 square feet. The aggregate width of <br />openings at any floor level shall not exceed 25 percent of the length of the wall. (706.8) <br /> <br />If the building has a projection (overhang, canopy, etc) at the fire wall, the fire wall shall extend <br />to the outer edge of the horizontal projection. (706.5.2) <br />Exception 1: If projection is without concealed spaces, fire wall may stop at the exterior wall if <br />the exterior wall and projection on each side of the fire wall is 1-hour fire-resistive for the depth <br />of the projection on each side of the fire wall. <br />Exception 2: If projection has concealed space and is noncombustible, fire wall may stop at the <br />exterior wall if the projection has a one hour wall in the concealed space and the exterior wall <br />and projection is 1-hour fire-resistive for the depth of the projection on each side of the fire wall. <br />Exception 3: If projection has concealed space and is combustible, fire wall may stop at the <br />exterior wall if the fire wall extends through the projection in the concealed space and the <br />exterior wall and projection is 1-hour fire-resistive for the depth of the projection on each side of <br />the fire wall. <br /> <br />If the fire wall intersects an exterior wall at less than 180 degrees, the fire-resistance rating for <br />the exterior walls on both sides of the fire wall shall have a 1-hour fire-resistance rating with 3/4 <br />hour opening protection. The fire-resistance rating of the exterior wall shall extend a minimum <br />of 4 feet on each side of the intersection. (706.5.1) <br /> <br />Fire walls shall be designed and constructed to allow collapse of the structure on either side <br />without collapse of the wall under fire conditions. (706.2) <br /> <br /> <br />
