29、 NFPA 495, Explosive Materials Code, was prepared by the Technical Commit-tee on Explosives. It was issued by the Standards Council on November 27, 2012, with aneffective date of December 17, 2012, and supersedes all previous editions.This edition of NFPA 495 was approved as an American National Sta
30、ndard on December17, 2012.Origin and Development of NFPA 495This code was originally issued in 1912 under the title Suggested State Law to Regulate theManufacture, Storage, Sale, and Use of Explosives. The second edition was issued in 1941 by theCommittee on Laws and Ordinances and retitled Suggeste
31、d Explosives Ordinance forCities. Later,the document was designated as NFPA 495L.After being assigned to the Committee on Chemicals and Explosives, a new edition wasissued in 1959. This was retitled as the Code for the Manufacture, Transportation, Storage, and Useof Explosives and Blasting Agents an
32、d redesignated as NFPA 495.Following the reorganization of the committee in 1960, the responsibility for amendmentsto NFPA 495 was assigned to the Sectional Committee on Explosives. This committee reportedto the Correlating Committee of the Committee on Chemicals and Explosives. Revised edi-tions we
33、re issued in 1962, 1965, 1967, 1968, 1969, and 1970. A new edition was issued in 1972,with the document title revised to Code for the Manufacture, Transportation, Storage, and Use ofExplosive Materials. A subsequent edition followed in 1973.Following the issuance of the 1973 edition, the Sectional C
34、ommittee on Explosives wasredesignated as a Technical Committee. In 1976, the committee began a detailed reviewintended to amend requirements to eliminate conflicts with the regulations promulgated bythe various federal agencies concerned with explosive materials (e.g., U.S. Bureau of Alcohol,Tobacc
35、o, and Firearms; U.S. Mine Safety and Health Administration; and U.S. Department ofTransportation). This effort resulted in the 1982 edition, which was followed by a new editionin 1985. In 1990, the document was again revised and the title changed to Explosive MaterialsCode. The 1992 edition incorpo
36、rated various technical and editorial amendments.The 1996 edition incorporated changes in the classification of explosives to conform withU.S. Department of Transportation “Hazardous Materials Regulations,” which in turn wasbased on United Nations Recommendations on the Transport of Dangerous Goods.
37、 The 1996edition also included technical and editorial amendments.The 2001 edition of NFPA 495 included technical and editorial amendments highlightedby an increase in the amount of smokeless propellants permitted to be stored on the shelvesof retail establishments. The change was needed due to the
38、reclassification of certain explo-sive materials by the U.S. Department of Transportation.In the 2006 edition, a new chapter on Manufacturing and Testing was added. The codeadded updated tables based on the most current IME industry practices. The Committee alsoprepared technical and editorial amend
39、ments to comply with the Manual of Style for NFPATechnical Committee Documents.The 2010 edition contained updated definitions reflecting changes in federal regulatoryprovisions. A security plan was now required as part of the permitting process for explosivematerials, and new requirements for site c
40、ontrol were also included. As of the 2010 edition,the code now allows quantitative risk assessment (QRA) to be used where the quantitydistance (QD) requirements cannot be met. With the introduction of QRA, the siting re-quirements now recognize the QRA method in addition to the traditional American
41、Table ofDistances. The Committee also modified quantity limits for display or storage of certain smallarms primers.4951NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.The 2013 edition contains updates to
42、 the ground vibration limitations in Chapter 11, Ground Vibration, Air Over-pressure, Flyrock, and Gases to reflect the advancement and availability of blasting seismograph equipment. The codenow has two options for limiting ground vibrations: monitoring with a blasting seismograph or using the scal
43、eddistance equations. The Committee also has made several editorial and reference updates to the code.4952 EXPLOSIVE MATERIALS CODE2013 EditionTechnical Committee on ExplosivesLon D.
