Authority Having JurisdictionAuthority Having Jurisdiction.*.* The organization,
office, or individual responsible for approving
equipment, materials, an installation, or a procedure.
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.

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.
