22、Rights Reserved. NFPA30 Flammable and Combustible Liquids Code 2008 Edition This edition of NFPA 30, Flammable and Combustible Liquids Code, was prepared by the Technical Committee on Fundamentals, the Technical Committee on Operations, the Tech- nical Committee on Storage and Warehousing of Contain
23、ers and Portable Tanks, and the Technical Committee on Tank Storage and Piping Systems, and released by the Technical Correlating Committee on Flammable and Combustible Liquids. It was issued by the Stan- dards Council on July 26, 2007, with an effective date of August 15, 2007, and supersedes all p
24、revious editions. This edition of NFPA30 was approved as anAmerican National Standard onAugust 15, 2007. Origin and Development of 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 Liqu
25、ids. In 1957, the format was changed to a code, although the technical requirements and provisions remained the same. During its 90-year existence, numerous revised editions have been published as dictated by experience and advances in technology. A brief review of the major changes adopted over the
26、 previous seven editions follows. In 1984, the chapter covering automotive and marine service stations was removed from NFPA30 and was used as the basis for a separate document, NFPA30A, Automotive and Marine ServiceStationCode,nowtitledCodeforMotorFuelDispensingFacilitiesandRepairGarages.In1987, Ch
27、apter 5 (Industrial Plants), Chapter 6 (Bulk Plants and Terminals), Chapter 7 (Process Plants), and Chapter 8 (Refineries, Chemical Plants, and Distilleries) were combined into a single chapter on operations. In 1990, a new section was added to Chapter 4 to address hazardous materials storage locker
28、s, and more detailed guidance was added to Section 5-3 to address ventilation of enclosed process areas and for estimation of fugitive emissions. In 1993, Chapter 2, Tank Storage, was amended to allow combined remote impounding and diking systems and to provide relief from the spill control requirem
29、ents for certain secondary containmenttype tanks. Also, Chapter 4, Container and Portable Tank Storage, was com- pletely rewritten so that its requirements were presented more clearly, especially for mercan- tile occupancies. In 1996, the following major changes were incorporated: requirements for t
30、emporary and permanent closure of underground storage tanks; requirements for tightness testing of tanks of 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
31、 following major changes were incorporated: complete editorial rewrites of Chapter 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 Class II and C
32、lass III liquids, along with fire protection system design criteria for them; simplified spill containment and drainage requirements; new fire protection design criteria for a number of flammable and combustible liquid commodities; expansion of the requirements for construction and separation of pro
33、cess buildings; a new section addressing recirculating heat transfer fluid heating systems; a new section addressing solvent recovery distillation units; and consolidation into a new Chapter 6 of all requirements for hazardous location electrical area classification. The 2003 edition of NFPA 30 inco
34、rporated the following changes: (1) All mandatory referenced publications were relocated to Chapter 2, and all definitions relocated to Chapter 3. All subsequent chapters were renumbered accordingly. (2) Numerous occupancy definitions were either added or corrected to correlate with NFPA 1, Uniform
35、Fire Code; NFPA 101, Life Safety Code; and NFPA 5000, Building Construction and Safety Code. 301 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts, 02169. (3) Separation distance requirements for protected above
36、ground tanks were reduced, and separation distance re- quirements for tanks in vaults were eliminated. (4) Specialoperatingrequirementswereaddedforshop-fabricatedabovegroundtankswithabnormallylongvertical piping for fill and/or vent lines. (5) New criteria were added to Chapter 6, Container and Port
37、able Tank Storage, for maximum allowable container sizes. (6) Fire protection design criteria for unsaturated polyester resins were added. (7) Section D.5, which contains suggested fire protection design criteria using high-expansion foam systems for protection of liquids in 1-gallon plastic contain
38、ers, was added. (8) Revisions were made to the spacing requirements and construction requirements for process buildings. (9) Special requirements were added for insulated piping for recirculating heat transfer systems. (10) Permanent interconnections between fire water systems and process water syst
39、ems were prohibited. The 2008 edition of NFPA30 represents a complete editorial revision of the prior 2003 edition to implement NFPAs hazardous materials template, a formatting scheme intended to integrate a common organization and common outline for all NFPA codes and standards that address the var
40、ious types of hazardous materials. As a result of the implementation of the template, the eight chapters that comprised the 2003 edition of NFPA30 have been subdivided into 29 shorter, more narrowly focused chapters. Code requirements that are generally applicable to all facilities that store, handl
41、e, and use flammable and combustible liquids have been relocated to the beginning of NFPA30. Chapters dealingwithbulkstorageandbulkhandlingofliquidshavebeenmovedtotheendofNFPA30,basedonthereasoning that not all codes and standards dealing with hazardous materials include provisions for bulk storage.
42、 In addition to the major editorial revision, the 2008 edition of NFPA 30 incorporates the following significant technical changes: (1) Several new definitions have been added to Chapter 3 to assist the user in applying the requirements of the code. Some existing definitions in Chapter 3 have been c
43、hanged to read the same as the preferred definitions in the NFPA Glossary of Terms. Where possible, secondary definitions have been moved to appropriate chapters. (2) New corrosion protection requirements have been added for nonmetallic tanks (21.4.5). (3) The requirements for construction of vaults
44、 (Section 25.5) have been improved for clarity. (4) Additional requirements for fire-resistant tanks have been added (Section 22.9). (5) The maximum capacity for secondary containmenttype tanks storing Class II and Class IIIA liquids has been increased from 12,000 gal to 20,000 gal (from 45,000 L to
45、 76,000 L) (22.11.4). (6) New requirements for periodic testing, maintenance, inspection, and repair of aboveground storage tanks have been added (Sections 21.5, 21.8, and 22.17). (7) Overfill prevention requirements have been revised so that they apply to all tanks larger than 1320 gal (5000 L) cap
46、acity (21.7.1). (8) Special requirements for marine piping systems have been added (Section 27.11). (9) Chapter 6, Container and PortableTank Storage, as written in the 2003 edition, has been completely replaced by Chapters 9 through 16 of this edition. These new chapters regulate storage of contain
47、ers, portable tanks, and intermediate bulk containers in a manner that is consistent with model building codes, such as NFPA 5000, Building Construction and Safety Code, and model fire prevention codes, such as NFPA1, Uniform Fire Code, and incorporate the concepts of maximum allowable quantities (M
48、AQs), control areas, and protection levels. (10) Fire protection design criteria for inside storage areas have been expanded to include requirements for small plastic containers of Class IB, IC, II, and III liquids in corrugated cartons and for Class IIIB liquids in corrugated cardboard intermediate
49、 bulk containers with plastic inner liners (Chapter 16). 302FLAMMABLE AND COMBUSTIBLE LIQUIDS CODE 2008 Edition -,-,- Technical Correlating Committee on Flammable and Combustible Liquids (FLC-AAC) Jack Woycheese, Chair Hughes Associates, Incorporated, CA SE John A.
