Notice Concerning Code Interpretations: This 11th edition of the LP-Gas Code Handbook is based on the 2017 edition of NFPA 58. All NFPA codes, standards, recomme
9、nded practices, and guides (“NFPA Standards”) are developed in accordance with the published procedures of the NFPA by technical committees comprised of volunteers drawn from a broad array of relevant interests. The handbook contains the complete text of NFPA58 and any applicable Formal Interpretati
10、ons issued by the NFPA at the time of publication. This NFPA Standard is accompanied by explanatory commentary and other supplementary materials. The commentary and supplementary materials in this handbook are not a part of the NFPA Standard and do not constitute Formal Interpretations of the NFPA (
11、which can be obtained only through requests processed by the responsible technical committees in accordance with the published procedures of the NFPA). The commentary and supplementary materials, therefore, solely reflect the personal opinions of the editor or other contributors and do not necessari
12、ly represent the official position of the NFPA or its technical committees. REMINDER: UPDATING OF NFPA STANDARDS NFPA 58, Liquefied Petroleum Gas Code, like all NFPA codes, standards, recommended practices, and guides (“NFPA Standards”), may be amended from time to time through the issuance of Tenta
13、tive Interim Amendments or corrected by Errata. An official NFPA Standard at any point in time consists of the current edition of the document together with any Tentative Interim Amendment and any Errata then in effect. In order to determine whether an NFPA Standard has been amended through the issu
14、ance of Tentative Interim Amendments or corrected by Errata, visit the “Codes & Standards” section on NFPAs website. There, the document information pages located at the “List of NFPA Codes & Standards” provide up-to-date, document-specific information, including any issued Tentative Interim Amendme
15、nts and Errata. To view the document information page for a specific NFPA Standard, go to http:/www.nfpa.org/docinfo to choose from the list of NFPA Standards, or use the search feature to select the NFPA Standard number (e.g., NFPA 58). The document information page includes postings of all existin
16、g Tentative Interim Amendments and Errata.

42、s vii BK-NFPA-58HB17-160243-FM.indd 7 09/11/16 6:53 PMviii Foreword Preface The eleventh edition of the LP-Gas Code Handbook continues the tradition begun by Wilbur L. Walls, editor of the first edition in 1986. The handbook provides commentary that brings the legalistic language of the code to life
43、. The code must be written using a technically clear, usable, and enforceable style only. It cannot include the guidance and explanations that clarify the intent and common application of the requirements. This limitation can make it difficult in application, where examples and intent are the most u
44、seful. This is where the handbook authors and editors have stepped in. The commentary and supplements provide guidance, recommendations, history, and common practices for the use of liquefied petroleum gas (LP-Gas) as a fuel. Features have been added to further illustrate the intent of the code. The
45、 2017 edition of the code contains several important changes, including the following:1. An all-new chapter (Chapter 12) has been added to update the technology now available for over-the-road vehicles utilizing LP-Gas. 2. New definitions, construction, transportation, and location requirements have
46、 been added for skid tanks and porta-pacs. 3. NFPA 58s scope has been expanded to include hot air balloons, with requirements ref- erencing the current state of federal laws regarding their use and construction. This edi- tion also includes new requirements and guidance on how to conduct liquid tran
47、sfer into these containers that were previously not covered by the code. 4. Revised snow load requirements for container or piping protection are based on calcula- tions and snowfall maps from ASCE 7, Minimum Design Loads for Buildings and Other Structures. The threshold for protecting containers an
48、d appurtenances from snow has been raised to 100 lb/ft 2(488 kgf/m 2 ). 5. Basic fire extinguisher requirements are centralized to Section 4.7, with individual capac- ity requirements remaining in the specific application section. 6. Appurtenance requirements in Table 5.9.4.1(B) have been expanded t
49、o cover containers (except DOT Spec. 39, less than 2 lb propane capacity). 7. Universal tanks have been permitted to be filled in the horizontal or vertical orientation, as long as the positioning slot is in the correct orientation. 8. New requirements in Chapter 6 address the placing of ASME tanks that have been dis- connected from use. 9. Vehicular barrier protection (VBP) for cylinders protected in a metal cabinet have been removed, along with changing the VBP requirement for 12,000 lb (53,375 N) protection for vehicle fuel dispensers to 6,000 lb (26.688 N).
