A.3.2.2 Authority Having Jurisdiction (AHJ). The phrase “authority having jurisdiction,” or its acronym AHJ, is used in NFPA documents in a broad manner, since jurisdictions and approval agencies vary, as do their responsibilities. Where public safety is primary, the authority having jurisdiction may be a federal, state, local, or other regional department or indi‐ vidual such as a fre chief; fre marshal; chief of a fre preven‐ tion bureau, labor department, or health department; building offcial; electrical inspector; or others having statutory author‐ ity. For insurance purposes, an insurance inspection depart‐ ment, rating bureau, or other insurance company representative may be the authority having jurisdiction. In many circumstances, the property owner or his or her designa‐ ted agent assumes the role of the authority having jurisdiction; at government installations, the commanding offcer or depart‐ mental offcial may be the authority having jurisdiction. A.3.2.3 Listed. The means for identifying listed equipment may vary for each organization concerned with product evalua‐ tion; some organizations do not recognize equipment as listed unless it is also labeled. The authority having jurisdiction should utilize the system employed by the listing organization to identify a listed product.
