A-1-8 (3.2.2) Authority Having Jurisdiction.A-1-8 (3.2.2) Authority Having Jurisdiction. The phrase “authority having jurisdiction” 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 individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the authority having jurisdiction. In many circumstances, the property owner or his or her designated agent assumes the role of the authority having jurisdiction; at government installations, the commanding officer or departmental official may be the authority having jurisdiction.

NFPA 20 (3.2.1)NFPA 20 (3.2.1)Approved.*Approved.* Acceptable to the Acceptable to the authority having jurisdiction.authority having jurisdiction.A-1-8 (A.3.2.1) Approved. A-1-8 (A.3.2.1) Approved. The National Fire Protection Association does not approve, inspect, or certify any installations, procedures, equipment, or materials; nor does it approve or evaluate testing laboratories. In determining the acceptability of installations, procedures, equipment, or materials, the authority having jurisdiction may base acceptance on compliance with NFPA or other appropriate standards. In the absence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority having jurisdiction may also refer to the listings or labeling practices of an organization ( UL or <FM> ) ( UL or <FM> ) that is concerned with product evaluations and is thus in a position to determine compliance with appropriate standards for the current production of listed items.
