30、ttee on Operations, the Tech-nical Committee on Storage and Warehousing of Containers and Portable Tanks, and theTechnical Committee on Tank Storage and Piping Systems and released by the CorrelatingCommittee on Flammable and Combustible Liquids. It was issued by the Standards Councilon April 29, 20

31、14, with an effective date of May 19, 2014, and supersedes all previous editions.This edition of NFPA 30 was approved as an American National Standard on May 19, 2014.Origin and Development of NFPA 30From 1913 to 1957, this document was written as a model municipal ordinance known asthe Suggested Or

32、dinance for the Storage, Handling, and Use of Flammable Liquids. In 1957, theformat was changed to a code, although the technical requirements and provisions remainedthe same. Since its inception numerous revised editions have been published as dictated byexperience and advances in technology.A brie

33、f review of the major changes adopted since 1981 follows. In 1984, the chapter onautomotive and marine service stations was removed from NFPA 30 and was replaced with anew document, NFPA 30A, Automotive and Marine Service Station Code, now titled Code for MotorFuel Dispensing Facilities and Repair G

34、arages. In 1987, Chapter 5 (Industrial Plants), Chapter 6(Bulk Plants and Terminals), Chapter 7 (Process Plants), and Chapter 8 (Refineries, Chemi-cal Plants, and Distilleries) were combined into a single chapter on operations. In 1990, a newsection was added to address hazardous materials storage l

35、ockers, and more detailed guid-ance was added to address ventilation of enclosed process areas and for estimation of fugitiveemissions. In 1993, the chapter on tank storage was amended to allow combined remoteimpounding and diking systems and to provide relief from the spill control requirements for

36、certain secondary containmenttype tanks. Also, the chapter on container and portable tankstorage was completely rewritten so that its requirements were presented more clearly, espe-cially for mercantile occupancies.In 1996, the following major changes were incorporated: requirements for temporary an

37、dpermanent closure of underground storage tanks; requirements for tightness testing of tanksof specific design; recognition of intermediate bulk containers; and mandatory fire protec-tion design criteria for inside storage of liquids in storage rooms and liquid warehouses.In 2000, the following majo

38、r changes were incorporated: complete editorial rewrites ofChapter 2, Tank Storage, and Chapter 3, Piping Systems; requirements for vaults for above-ground tanks and for protected aboveground tanks; recognition of certain nonmetallic inter-mediate bulk containers for storage of Class II and Class II

39、I liquids, along with fire protectionsystem design criteria for them; simplified spill containment and drainage requirements; newfire protection design criteria for a number of flammable and combustible liquid commodi-ties; expansion of the requirements for construction and separation of process bui

40、ldings; anew section addressing recirculating heat transfer fluid heating systems; a new section ad-dressing solvent recovery distillation units; and consolidation of all requirements for hazard-ous location electrical area classification into a single chapter.The 2003 edition of NFPA 30 incorporate

41、d the following changes:(1) Numerous occupancy definitions were either added or corrected to correlate withNFPA 1, Uniform Fire Code; NFPA 101, Life Safety Code; and NFPA 5000, Building Con-struction and Safety Code.(2) Separation distance requirements for protected aboveground tanks were reduced, a

42、ndseparation distance requirements for tanks in vaults were eliminated.(3) Special operating requirements were added for shop-fabricated aboveground tanks withabnormally long vertical piping for fill and/or vent lines.301NFPA and National Fire Protection Association are registered trademarks of the

43、National Fire Protection Association, Quincy, Massachusetts 02169.(4) New criteria were added to Chapter 6, Container and Portable Tank Storage, for maximum allowable capacities ofacceptable container sizes.(5) Fire protection design criteria for unsaturated polyester resins were added.(6) Section D

44、.5, Recommended Fire Protection Design Criteria for High-Expansion Foam Fire Protection for Non-miscible Liquids, was added.(7) Revisions were made to the spacing requirements and construction requirements for process buildings.(8) Special requirements were added for insulated piping for recirculati

45、ng heat transfer systems.(9) Permanent interconnections between fire 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 NFPAshazardous materials template, a formatting scheme intended to int

46、egrate a common organization and commonoutline for all NFPA codes and standards that address the various types of hazardous materials. As a result of theimplementation of the template, the eight chapters that the 2003 edition of NFPA 30 comprised were subdivided andrearranged into 29 shorter, more n

47、arrowly focused chapters. Requirements that are generally applicable to all facilitiesthat store, handle, and use flammable and combustible liquids were relocated to the beginning of the code. Chaptersdealing with bulk storage and bulk handling of liquids were moved to the end of the code, based on

48、the reasoning thatnot 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 technical changes:(1) Several new definitions were added to assist the user in applying the

49、 requirements of the code. Some existingdefinitions in Chapter 3 were changed to read the same as the preferred definitions in the NFPAGlossary ofTerms.Where possible, secondary definitions were moved to appropriate chapters.(2) Chapter 6, Container and Portable Tank Storage, was replaced by Chapters 9 through 16 of the 2008 edition.These new chapters regulated storage of containers, portable tanks, and intermediate bulk containers in amanner that is consistent with model building codes, such as NFPA5000, Building Construction and Safety Code,and model fire prevention co
