Which organization is responsible for listing standards referenced in LP-Gas installation guidelines?

• A. NFPA
• B. OSHA
• C. EPA
• D. Underwriters Laboratories, Inc.

Answer: (D)

Standards referenced in LP-Gas installation guidelines come from the organization that tests and lists equipment to those safety standards: Underwriters Laboratories, Inc. UL develops safety standards and provides listings for products used with propane systems, like tanks, regulators, piping, and appliances. When a guideline cites UL standards, it means the equipment should be UL-listed or meet UL safety criteria, ensuring compatibility and safety in installation. Other options aren’t about listing standards: OSHA and EPA are regulatory bodies focused on workplace and environmental rules, and NFPA writes the standards themselves rather than performing the listing role.
