NFPA 30 Flammable and Combustible Liquids Code 2018 Edition This edition of NFPA 30, Flammable and Combustible Liquids Code,
32、 was prepared by the Technical Committees on Fundamentals, Operations, Storage and Warehousing of Containers and Portable Tanks, and Tank Storage and Piping Systems, released by the Correlating Committee on Flammable and Combustible Liquids, and acted on by NFPA at its June Association Technical Mee
33、ting held June 47, 2017, in Boston, MA. It was issued by the Standards Council on August 17, 2017, with an effective date of September 6, 2017, and supersedes all previous editions. This edition of NFPA 30 was approved as an American National Standard on September 6, 2017. Origin and Development of
34、NFPA 30 From 1913 to 1957, this document was written as a model municipal ordinance known as the Suggested Ordinance for the Storage, Handling, and Use of Flammable Liquids. In 1957, the format was changed to a code, although the technical requirements and provisions remained the same. Since its inc
35、eption, numerous revised editions have been published as dictated by experience and advances in technology. A brief review of the major changes adopted since 1981 follows. In 1984, the chapter on automotive and marine service stations was removed from NFPA 30 and was replaced with a new document, NF
36、PA 30A, Automotive and Marine Service Station Code, now titled Code for Motor Fuel Dispensing Facilities and Repair Garages. In 1987, Chapter 5 (Industrial Plants), Chapter 6 (Bulk Plants and Terminals), Chapter 7 (Process Plants), and Chapter 8 (Reneries, Chemical Plants, and Distilleries) were com
37、bined into a single chapter on operations. In 1990, a new section was added to address hazardous materials storage lockers, and more detailed guidance was added to address ventilation of enclosed process areas and for estimation of fugitive emissions. In 1993, the chapter on tank storage was amended
38、 to allow combined remote impounding and diking systems and to provide relief from the spill control requirements for certain secondary containmenttype tanks. Also, the chapter on container and portable tank storage was completely rewritten so that its requirements were presented more clearly, espec
39、ially for mercantile occupancies. In 1996, the following major changes were incorporated: requirements for temporary and permanent closure of underground storage tanks; requirements for tightness testing of tanks of specic design; recognition of intermediate bulk containers; and mandatory re protect
40、ion design criteria for inside storage of liquids in storage rooms and liquid warehouses. In 2000, the following major changes were incorporated: complete editorial rewrites of Chapter 2, Tank Storage, and Chapter 3, Piping Systems; requirements for vaults for aboveground tanks and for protected abo
41、veground tanks; recognition of certain nonmetallic intermediate bulk containers for storage of Class II and Class III liquids, along with re protection system design criteria for them; simplied spill containment and drainage requirements; new re protection design criteria for a number of ammable and
42、 combustible liquid commodities; expansion of the requirements for construction and separation of process buildings; a new section addressing recirculating heat transfer uid heating systems; a new section addressing solvent recovery distillation units; and consolidation of all requirements for hazar
43、dous location electrical area classication into a single chapter. The 2003 edition of NFPA 30 incorporated the following changes: (1) Numerous occupancy denitions were either added or corrected to correlate with NFPA 1, Uniform Fire Code ; NFPA 101 , Life Safety Code ; and NFPA 5000 , Building Const
44、ruction and Safety Code . (2) Separation distance requirements for protected aboveground tanks were reduced, and separation distance requirements for tanks in vaults were eliminated.FLAMMABLE AND COMBUSTIBLE LIQUIDS CODE 30-2 2018 Edition (3) Special operating requirements were added for shop-fabric
45、ated aboveground tanks with abnormally long vertical piping for ll and/or vent lines. (4) New criteria were added to Chapter 6, Container and Portable Tank Storage, for maximum allowable capacities of acceptable container sizes. (5) Fire protection design criteria for unsaturated polyester resins we
46、re added. (6) Section D.5, Recommended Fire Protection Design Criteria for High-Expansion Foam Fire Protection for Nonmiscible Liquids, was added. (7) Revisions were made to the spacing requirements and construction requirements for process buildings. (8) Special requirements were added for insulate
47、d piping for recirculating heat transfer systems. (9) Permanent interconnections between re water systems and process water systems were prohibited. The 2008 edition of NFPA 30 incorporated a complete editorial revision of the prior edition to implement NFPAs hazardous materials template, a formatti
48、ng scheme intended to integrate a common organization and common outline for all NFPA codes and standards that address the various types of hazardous materials. As a result of the implementation of the template, the eight chapters that the 2003 edition of NFPA 30 comprised were subdivided and rearra
49、nged into 29 shorter, more narrowly focused chapters. Requirements that are generally applicable to all facilities that store, handle, and use ammable and combustible liquids were relocated to the beginning of the code. Chapters dealing with bulk storage and bulk handling of liquids were moved to the end of the code, based on the reasoning that not all codes and standards dealing with hazardous materials include provisions for bulk storage. In addition to the editorial revision, the 2008 edition of NFPA 30 incorporated the following tec
