NFPA 58 Liqueed Petroleum Gas Code 2017 Edition This edition of NFPA 58, Liqueed Petroleum Gas Code, was prepared by the Technical Committee on Liquee

29、d Petroleum Gases and acted on by NFPA at its June Association Technical Meeting held June 1316, 2016, in Las Vegas, NV. It was issued by the Standards Council on August 4, 2016, with an effective date of August 24, 2016, and supersedes all previous editions. This edition includes the following usab

30、ility features as aids to the user. Technical changes are indicated by gray shading of the sections. An entire gure caption or table title with gray shading indicates a change to an existing gure or table. New sections, gures, and tables are indicated by a bold, N in a gray box to the left of the ne

This edition of NFPA 58 was approved as an American National Standard on August 24, 2016. Origin and Development of NFPA 58 The rst NFPA standard on LP-Gas was adopted

32、 in 1932. In 1940, several standards were combined and adopted as NFPA 58. Revisions of NFPA 58 were adopted in 1934, 1937, 1939, 1940, 1943, 1946, 1948, 1950, 1951, 1952, 1953, 1954, 1955, 1956, 1957, 1958, 1959, 1960, 1961, 1965, 1967, 1969, 1972, 1974, 1976, 1979, 1983, 1986, 1989, 1992, 1995, 19

33、98, 2001, 2004, 2008, 2011, 2014, and the latest one, in 2017. The 2011 edition of NFPA 58 included several signicant changes. The installation of underground LP-Gas storage containers required cathodic protection systems, and the systems were required to be monitored to verify that they were provid

34、ed protection. The requirement that a pressure relief valve be piped vertically upward 7 ft (2.1 m) from the valve was deleted because the committee could nd no technical reason to justify it. Former railroad tank car tanks were no longer allowed to be installed as permanent storage containers becau

35、se they were not constructed to the ASME Boiler and Pressure Vessel Code, and additional recommendations for training were added to Annex A. The 2014 edition harmonized container requirements for containers with 4000 gal and less water capacity (wc) and greater than 4000 gal wc. A bulk plant and an

36、industrial plant are dened as facilities that store more than 4000 gal wc (15.2 m 3 ), which is the reason for the demarcation point of 4000 gal wc. A new denition was added for vehicular barrier protection (VBP). There are many installations where the container and valves are required to be protect

37、ed from vehicular impact, but no specic information was available as to what constituted such protection. In addition to the denition describing VBP, extensive annex material was incorporated. Prescriptive requirements also were added for VBP of LP-Gas dispensers. Qualications of personnel were expa

38、nded for clarication in Chapter 4. The requirements, which originated as a Temporary Interim Amendment (TIA) to the 2011 edition, specied which personnel must be trained and in which topics they must be trained. New requirements included the covering of tank heaters, and requirements for vaporizers

39、were updated. The 2014 edition included new requirements to provide cathodic protection for underground metallic piping systems greater than 2 in. diameter (5.08 cm). Previously, all underground metallic piping was only required to be coated or painted. The new requirements for piping systems were v

40、ery similar to those for cathodic protection of underground containers. The 2017 edition includes several signicant changes. In previous editions, hot air balloons were not covered under the scope of NFPA 58, but they now are included with requirements referencing the current state of federal law re

41、garding their use and construction. The requirements for hot air balloons are included in the corresponding sections for scope, construction, and liquid transfer. The requirements for when a container or piping must be protected from snow loads have been alteredLIQUEFIED PETROLEUM GAS CODE 58-2 2017

42、 Edition to allow for calculations and snowfall maps from ASCE 7. The threshold for protecting containers and appurtenances from snow has been raised to 100 lb/ft 2(488 kgf/m 2 ). Vehicle barrier protection (VBP) for cylinders protected in a metal cabinet have been removed. The VBP requirement for 1

43、2,000 lb (53,375 N) protection for vehicle fuel dispensers also has been removed. A new chapter (Chapter 12) updates the technology now available for over-the-road vehicles utilizing LP-Gas. New denitions, construction, transportation, and location requirements have been added for skid tanks and por

44、ta-pacs. Also, there are now requirements in Chapter 6 for the placing of ASME tanks that have been disconnected from use. Fire extinguisher requirements have been centralized to Section 4.7 for basic requirements, but individual capacity requirements remain in the specic application section. The ap

45、purtenance requirements in Table 5.9.4.1(B) have been expanded in the 2017 edition to cover containers, except DOT Spec. 39, less than 2 lb propane capacity. Universal tanks are now permitted to be lled in the horizontal or vertical orientation as long as the positioning slot is in the correct orien
