1704.11.7 Inspection of Existing Sprayed Fire-Resistant Materials During Alterations in Office Spaces and Spaces Classified in Occupancy Group B

In office spaces and spaces classified in Occupancy Group B, where an alteration exposes any required sprayed fire-resistant materials on structural members or where, pursuant to an alteration, persons are required to enter or access areas in which such sprayed fire-resistant materials are capable of being observed, the existing required sprayed fire-resistant materials shall be subject to special inspection. Such inspection shall require a determination, based on visual inspection, (i) that the existing sprayed fire-resistant materials as originally applied or installed comply with the applicable requirements of this code, including those for installation methods, materials, thickness and coverage; and (ii) that, since their original application, the integrity of the existing sprayed fire-resistant materials has not been compromised, damaged or displaced by the current alteration or by any prior alteration or other event.
