  21. 22. SMOKE BARRIER <ul><li>Divides a building into sections to contain the migration of smoke. </li></ul><ul><li>Provides barrier between the building’s exterior walls and from floor slab to floor or roof deck. (IBC) </li></ul><ul><li>Required in hospitals, nursing homes, and other areas requiring extra time to evacuate occupants. </li></ul>
  22. 23. SMOKE PARTITION <ul><li>Provides barrier to prevent the passage of smoke. </li></ul><ul><li>Does not run between building exterior walls. Usually encloses certain rooms. Example: storage rooms, soiled utility rooms, clean linen rooms, and etc. </li></ul>
