Liquefied Petroleum Gas Code

2014 Edition

This edition of NFPA 58, Liquefied Petroleum Gas Code, was prepared by the Technical Com-ittee on Liquefied Petroleum Gases and acted on by NFPA at its June Association Technical eeting held June 10–13, 2013, in Chicago, IL. It was issued by the Standards Council on ugust 1, 2013, with an effective date of August 21, 2013, and supersedes all previous editions.

Tentative interim amendments (TIAs) to Paragraphs 6.12.9, 11.1.1 and its Annex A mate-ial, and 11.15.2 (relocated to Section 6.26) were issued on August 1, 2013. For further infor-ation on tentative interim amendments, see Section 5 of the NFPA Regulations Governing ommittee Projects available at: http://www.nfpa.org/assets/files/PDF/CodesStandards/ IAErrataFI/TIARegs.pdf.

This edition of NFPA 58 was approved as an American National Standard on August 21, 2013.

Origin and Development of NFPA 58 The first NFPA standard on LP-Gas was adopted in 1932. In 1940, several standards were ombined and adopted as NFPA 58.

Revisions of NFPA 58 were adopted in 1934, 1937, 1939, 1940, 1943, 1946, 1948, 1950, 1951, 952, 1953, 1954, 1955, 1956, 1957, 1958, 1959, 1960, 1961, 1965, 1967, 1969, 1972, 1974, 1976, 979, 1983, 1986, 1989, 1992, 1995, 1998, 2001, 2004, 2008, and 2011.

The 2011 edition of NFPA 58 included several significant changes. The installation of nderground LP-Gas storage containers required cathodic protection systems, and the sys-ems were required to be monitored to verify that they were provided protection. The require-ent that a pressure relief valve be piped vertically upward 7 ft from the valve was deleted ecause the committee could find no technical reason to justify it. Former railroad tank car anks were no longer allowed to be installed as permanent storage containers because they ere not constructed to the ASME Boiler and Pressure Vessel Code, and additional recommenda-ions for training were added to Annex A.

The 2014 edition harmonizes container requirements for containers 4000 gal and less ater capacity and greater than 4000 gal water capacity (wc). A bulk plant and an industrial lant are defined as facilities storing more than 4000 gal wc, which is the reason for the emarcation point of 4000 gal wc. A new definition was added for vehicular barrier protection VBP). There are many installations where the container and valves are required to be pro-ected from vehicular impact, but no specific information was provided as to what constituted uch protection. A new definition to describe VBP is incorporated into the 2014 edition, along ith extensive annex material. In addition, prescriptive requirements are added for VBP of P-Gas dispensers.

Qualifications of personnel have been expanded for clarification in Chapter 4. The require-ents, which originated as a Temporary Interim Amendment to the 2011 edition, specify which ersonnel must be trained and what topics they must be trained in. New requirements are in-luded covering tank heaters, and requirements for vaporizers have been updated.

Finally, the 2014 edition includes new requirements to provide cathodic protection for nderground metallic piping systems greater than 2 in. Previously, all underground metallic iping was only required to be coated or painted. The new requirements for piping systems re very similar to those for cathodic protection of underground containers.

Chapter 1 Administration

1.1* Scope. This code shall apply to the storage, handling, transportation, and use of liquefied petroleum gas (LP-Gas).

1.2 Purpose. (Reserved)

1.3 Application.

1.3.1 Application of Code. This code shall apply to the opera-tion of all LP-Gas systems, including the following:

(1) Containers, piping, and associated equipment, when de-livering LP-Gas to a building for use as a fuel gas.

(2) Highway transportation of LP-Gas.

(3) The design, construction, installation, and operation of marine terminals whose primary purpose is the receipt of LP-Gas for delivery to transporters, distributors, or users, except for marine terminals associated with refineries, petrochemicals, gas plants, and marine terminals whose purpose is the delivery of LP-Gas to marine vessels.

(4)*The design, construction, installation, and operation of pipeline terminals that receive LP-Gas from pipelines under the jurisdiction of the U.S. Department of Transportation (DOT) whose primary purpose is the receipt of LP-Gas for delivery to transporters, distributors, or users. Coverage shall begin downstream of the last pipeline valve or tank manifold inlet.

03E5149-7106-46A5-

1.3.2 Nonapplication of Code. This code shall not apply to

the following:

(1) Frozen ground containers and underground storage in caverns, including associated piping and appurtenances used for the storage of LP-Gas

(2) Natural gas processing plants, refineries, and petro-chemical plants

(3) LP-Gas at utility gas plants (including refrigerated stor-age) (see NFPA 59, Utility LP-Gas Plant Code)

(4)*Chemical plants where specific approval of construction and installation plans is obtained from the authority hav-ing jurisdiction

(5)*LP-Gas used with oxygen (6)*The portions of LP-Gas systems covered by NFPA 54

(ANSI Z223.1), National Fuel Gas Code, where NFPA 54 (ANSI Z223.1) is adopted, used, or enforced

(7) Transportation by air (including use in hot air balloons), rail, or water under the jurisdiction of the DOT

(8)*Marine fire protection

(9) Refrigeration cycle equipment and LP-Gas used as a re-frigerant in a closed cycle

(10) The manufacturing requirements for recreational ve-hicle LP-Gas systems that are addressed by NFPA 1192, Standard on Recreational Vehicles

(11) Propane vehicle fuel dispensers located at multiple fuel refueling stations (see NFPA 30A, Code for Motor Fuel Dis-pensing Facilities and Repair Garages)

1.4 Retroactivity. The provisions of this code reflect a consen-sus of what is necessary to provide an acceptable degree of protection from the hazards addressed in this code at the time it was issued.

1.4.1 Unless otherwise specified, the provisions of this code shall not apply to facilities, equipment, appliances, structures, or installations that existed or were approved for construction or installation prior to the effective date of the code. Equip-ment and appliances include stocks in manufacturers’ stor-age, distribution warehouses, and dealers’ storage and show-rooms in compliance with the provisions of this code in effect at the time of manufacture. Where specified, the provisions of this code shall be retroactive.

1.4.2 In those cases where the authority having jurisdiction

determines that the existing situation presents a distinct haz-ard to life and property, the authority having jurisdiction shall be permitted to apply retroactively any portions of this code that are deemed appropriate.

1.4.3 Where the application of the retroactivity requirements of this code are determined to be impractical in the judgment of the authority having jurisdiction, alternate requirements that provide a reasonable degree of safety shall be provided by the authority having jurisdiction.

1.5 Equivalency. Nothing in this code is intended to prevent

the use of systems, methods, or devices of equivalent or supe-rior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this code.

1.5.1 Technical documentation shall be submitted to the au-

thority having jurisdiction to demonstrate equivalency.

1.5.2 The system, method, or device shall be approved for the intended purpose by the authority having jurisdiction.
