Copyright 2017 National Fire Protection Association . All Rights Reserved. NFPA 1123 Code for Fireworks Display 2018 Edition This edition of NFPA 1123, Cod
32、e for Fireworks Display, was prepared by the Technical Committee on Pyrotechnics. It was issued by the Standards Council on August 1, 2017, with an effective date of August 21, 2017, and supersedes all previous editions. This edition of NFPA 1123 was approved as an American National Standard on Augu
33、st 21, 2017. Origin and Development of NFPA 1123 The development of NFPA 1123 began in 1975 with the submission to the Technical Committee on Pyrotechnics of a proposed standard drafted by the American Pyrotechnics Association. The proposed standard was redrafted and was ofcially adopted by the Nati
34、onal Fire Protection Association at its 1978 Fall Meeting. The 1978 edition was amended in 1980, and the amended version was adopted by the Association at its 1981 Fall Meeting. In the 1990 edition of NFPA 1123, the Committee initiated a complete revision of the document that incorporated a good dea
35、l of additional detail on the operation of outdoor reworks displays, including enhancements in the safe conduct of outdoor reworks displays by increasing the audience separation distances. The Committee also addressed the new technology of electrically ring outdoor displays of reworks. Generally, th
36、e Committee provided performance requirements rather than supply specic prescriptions for meeting those requirements. The 1995 edition of NFPA 1123 represented partial amendments to the document and included editorial revisions to improve its ability to be used, adopted, and enforced and to make it
37、conform with the Manual of Style for NFPA Technical Committee Documents. The Committee updated the denitions used for reworks to be consistent with the terminology used in the U.S. Department of Transportation regulations that incorporated the United Nations shipping designations for reworks (explos
38、ives), including the marking of aerial shells. The 1995 edition also incorporated a new chapter containing requirements for electrically ring reworks displays and rened the provisions for manually ring large-diameter aerial shells. The 2000 edition of NFPA 1123 contained three signicant changes. Fir
39、st, a new Chapter 4 on display reworks launched from oating vessels and oating platforms was added to the document. It provided guidance on the construction, sizing, operation, and egress requirements for those reworks displays launched from oating vessels and oating platforms. Second, requirements
40、for mortar installation and placement were added. The third signicant change revised and expanded the tables in Annex A that provided guidance on mortar wall thickness for steel, paper, high-density polyethylene (HDPE), and berglass mortars. Chapter 2 was also reorganized to provide a more logical s
41、equence. The 2005 edition contained three major revisions to the code. The Committee added smaller aerial shell sizes to the separation distances table in Chapter 5 and reorganized Chapter 5 to clarify the requirements for the various shell types. The reorganization of the chapter established clear
42、requirements for aerial shells, mines and comets, and ground display pieces. The 2005 edition also included new guidance on displays from rooftops and other limited or restricted access sites. The code also was reorganized according to the Manual of Style for NFPA Technical Committee Documents. The
43、2010 edition incorporated minor revisions to denitions, requirements for protection of ready boxes, and requirements for determining the fallout area and display site. The Committee also amended requirements pertaining to single-break aerial salute shells; requirements pertaining to handling of live
44、 components or unexploded shells; and requirements for angling aerial shells, comets and mines, and Roman candles and cakes.FIREWORKS DISPLAY 1123-2 2018 Edition The 2014 edition incorporated several revisions to denitions and added provisions for separation distances for marine preparation areas. T
45、his edition also increased spectator distances for elevated display sites, including these requirements in the spectator section of the code. Annex material was added for clarication of these separation distances. The 2018 edition has incorporated a number of changes to clarify existing requirements
46、 and to add new requirements to the code based on changes in the industry. Changes were made in a number of sections to address the stability of pyrotechnic devices and mortars, including prohibiting the use of plastic or zip ties to secure devices. Performance requirements were added for rack const
47、ruction and materials to ensure that the entire system functions as designed and protects the technicians and the public from injury should a catastrophic malfunction occur. A new subsection 4.7.1 was added to address the increasing use of densely packed trailers, which are increasingly used for rin
48、g pyrotechnics. This new subsection includes requirements on the construction material and the security and stabilization of racks on such trailers. The code was also modied to require additional information to the site plan for the use of elevated ring locations to assist the authority having juris
49、diction (AHJ) in the evaluation and approval of spectator separation distances. Other changes include the addition of annex material to clarify that the term fallout area does not include areas where cardboard and nonhazardous remnants of pyrotechnic devices might fall to the ground and the addition of eight hours of continuing education requirements for reworks operator license renewal every four years.COMMITTEE PERSONNEL 1123-3 2018 Edition Technical Committee on Pyrotechnics Gregory S.
