Where the Drawings indicate adjacent boxes or devices in rated partitions 28 that would reduce the fire rating of the partition if unprotected, suitable Listed protection methods shall be used to 29 insure the fire rating of the partition will not be decreased by the proximity of other boxes or penetrations. 30 31 Where recessed fixtures are used in fire rated ceilings, suitable construction shall be installed above and around the 32 fixture so that the fire rating of the ceiling is maintained. Refer to Architectural Drawings for fire ratings of ceilings. 33 34 Where recessed panelboards, recessed cabinets, or other items are located in a fire rated partition, suitable 35 construction behind and around the item shall be used to maintain the fire rating of the partition. 36 37 Where fire resistive insulation or other coverings have been applied to a structure or to structural elements to obtain a 38 fire rating and this insulation or covering is removed or otherwise disturbed by the installation of Division 26-28 39 components or other related items, this Contractor shall be responsible for restoring the material to a condition that 40 matches the original fire protective ability. 41 42 Approval must be obtained from the A-E before any boxes, devices, or other components are relocated for the 43 purpose of maintaining fire ratings. 44 45 46 TESTING LABORATORY APPROVAL 47 48 All equipment shall be approved for the intended use and shall be Labeled or Listed.
