Which term denotes the person or organization responsible for enforcing code requirements and approving equipment?

• A. Approved
• B. Alarm Signal
• C. Authority Having Jurisdiction
• D. Automatic

Answer: (C)

The term refers to the Authority Having Jurisdiction (AHJ). This is the person or organization charged with enforcing code requirements and approving equipment for use. In practice, the AHJ interprets applicable codes, issues permits, conducts inspections, and certifies that installations meet the safety standards before they can be used. In the field of flammable-refrigerant systems, the AHJ could be a local fire department, building department, or another official body within the jurisdiction, depending on local structure. Without AHJ approval, equipment and installations aren’t legally permitted, even if they meet technical specs.

The other terms don’t fit because they describe a status or component rather than the enforcing authority: "Approved" refers to a component or plan that has passed review, not the body that does the review; "Alarm signal" and "Automatic" relate to system features or functions, not to who enforces codes or approves equipment.
