It was issued by the Standards Council on January 16, 2004, with an effective date of February 5, 2004, and supersedes all previous editions. ThiseditionofNFPA58wasapprovedasanAmericanNationalStandardonJanuary16,2004. Origin and Development of NFPA 58 This first NFPA standard on LP-Gas was adopted in 1932. In the next eight years, separate standards covering various LP-Gas applications were adopted. In 1940, several standards were combined and adopted as NFPA 58. Revisions of NFPA 58 were adopted in 1943, 1946, 1948, 1950, 1951, 1952, 1953, 1954, 1955, 1956, 1957, 1958, 1959, 1960, 1961, 1965, 1967, 1969, 1972, 1974, 1976, 1979, 1982, 1985, 1988, 1992, 1995, 1998, and 2001. The 2001 edition was a complete revision of the code and included extensive editorial modifications that made the code clearer and easier to use. Major changes included a new Chapter 11, Operations and Maintenance, new retroactive requirements for valves with re- mote closing capability on all containers of 4000 gal to be completed within 10 years, and a requirement for a fire safety analysis for all installations of 4000 gal or more within three years of the effective date. The 2004 edition brings NFPA58 into compliance with the NFPA Manual of Style. Chapters 1 through 4 are taken from er Chapters 1 and 12. The remaining chapters are renumbered. The committee’s work to make NFPA58 clearer and easier to use continues with new tables and clearer requirements. New requirements include recertification criteria for cylinders and safety requirements for engine fuel cylinders. 58–1 Copyright National Fire Protection Association Provided by IHS under license with NFPA Not for ResaleNo reproduction or networking permitted without license from IHS --,,--,,,,,,,--- The Standard is downloaded from Standard Sharing Technical Committee on Liquefied Petroleum Gases Al Linder, Chair Watsonville, CA [SE] Theodore C.
