INTERNATIONAL BUILDING CODE
� IBC 2009 Edition Chapter 7� Section 702 “Fire Wall – a fire-resistance-rated wall having
protected opening, which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall.”
� Section 707 “Fire Barriers- a fire-resistance-rated wall assembly of materials designed to restrict the spread of fire in which continuity is maintained.”
� Section 709 “Fire Partitions- a vertical assembly of materials designed to restrict the spread of fire in which openings are protected.”
� Section 710 “Smoke Barriers – a continuous membrane, either vertical or horizontal, such as a wall, floor or ceiling assembly, that is designed and constructed to restrict the movement of smoke.”
Properties of a “Fire Wall”
� Fire-Resistance-Rated
� Extends continuously from foundation to or through roof
� Generally extends to outer edge of projecting elements (e.g. balconies, roof overhangs)
� Sufficient structural stability� to allow collapse of building on either side without wall
collapse� for duration of time required by the fire-resistance
rating
� Openings are protected (e.g. fire doors, duct dampers, penetrations, construction joints)

Fire WallFire WallFire WallFire Wall
Properties of a “Fire Barrier”
� Fire-Resistance-Rated
� Vertical or horizontal assembly that restricts spread offire
� Must span from floor/ceiling below to underside of floor or roof above� need not be continuous from story to story� must be continuous through concealed spaces
� Hollow vertical spaces within a fire barrier wall must be fire-blocked at every floor level
� Does not require structural independence from building on either side
� Openings are protected (e.g. fire doors, duct dampers, penetrations, construction joints)
Properties of a “Fire Partition”
� Vertical assembly that has a fire-resistance rating
� 1-hour fire resistance� 1/2 hour for dwelling/guestroom separation in
sprinklered buildings of IIB, IIIB, VB construction
� Extend from top of floor assembly below up to: � underside of floor/roof slab or deck above, OR
� underside of fire-resistance rated floor/ceiling or roof/ceiling assembly
� Must be securely attached

Properties of a “Smoke Barrier”
� Healthcare:� Extend from floor slab to floor/roof slab above, through
concealed spaces, extend continuously from exterior wall to exterior wall. All penetrations are properly sealed.
� Fire-resistance-rating• Existing building – ½ hour• New Building – 1 hour
� New Buildings at least two (2) smoke compartments are provided:• For every story with patient sleeping or treatment rooms• That have an occupant capacity of 50 or more people on non-sleeping stories
• On useable but non-occupied stories
� Limit the maximum size of each compartment to 22,500 square feet

� Two full-length layers of ½” type X gypsum wallboard applied vertically on each side. Second layer applied with joints offset one stud space. Screws on first layer 8” on center around perimeter and 12” on center on the intermediate 25 gauge stud. Screws on second layer 9” on center along vertical joints, 12” on center at intermediate studs, 24” on center along top & bottom runners
