From NFPA 25, 2008
4.1.5* Changes in Occupancy, Use, Process, or Materials. The property owner or occupant shall not make changes in the
occupancy, the use or process, or the materials used or stored in the building without evaluation of the fire protection systems
for their capability to protect the new occupancy, use, or materials.
4.1.5.1 The evaluation shall consider factors that include, but are not limited to, the following:
(1) Occupancy changes such as converting office or production space into warehousing
(2) Process or material changes such as metal stamping to molded plastics
(3) Building revisions such as relocated walls, added mezzanines, and ceilings added below sprinklers
(4) Removal of heating systems in spaces with piping subject to freezing
4.1.6 Addressing Changes in Hazard. Where changes in the occupancy, hazard, water supply, storage commodity, storage arrangement,
building modification, or other condition that affects the installation criteria of the system are identified, the property owner or occupant shall promptly take steps, such as contacting a qualified contractor, consultant, or engineer, and the authority having jurisdiction, to evaluate the adequacy of the installed system in order to protect the building or hazard in question.
4.1.6.1 Where the evaluation reveals a deficiency causing a threat to life or property, the property owner shall make appropriate
corrections. All requirements of the authority having jurisdiction shall be followed.
