What does AHJ stand for in propane regulations?

• A. Authority Having Jurisdiction
• B. Actual Handling Jurisdiction
• C. Administrative Hazard Judgment
• D. Approved Hydraulic Judgment

Answer: (A)

AHJ stands for Authority Having Jurisdiction. In propane regulations this refers to the official body—often a local or state agency such as the fire marshal, building department, or code official—that has the legal authority to enforce safety codes, review plans, issue permits, and perform inspections for propane installations. They determine whether a system meets the required standards and can require corrections or deny operation until compliance is achieved. The other options aren’t standard terms used in regulatory contexts, so they don’t describe who enforces and approves propane installations.
