7、d wildland-urban interface areas using prescriptiveand performance-related provisions. It is founded on data collected from tests and fire incidents,technical reports and mitigation strategies from around the world. This 2018 edition is fully compat-ible with all of the International Codes(I-Codes)

10、Wildland-Urban Interface Code, are used in a varietyof ways in both the public and private sectors. Most industry professionals are familiar with theI-Codes as the basis of laws and regulations in communities across the U.S. and in other countries.However, the impact of the codes extends well beyond

11、 the regulatory arena, as they are used in avariety of nonregulatory settings, including: Voluntary compliance programs such as those promoting sustainability, energy efficiencyand disaster resistance. The insurance industry, to estimate and manage risk, and as a tool in underwriting and ratedecisio

U.S. federal agencies, to guide construction in an array of government-owned properties. Facilities management. “Best p

College, university and professional school textbooks and curricula. Reference works related to building de

14、sign and construction.In addition to the codes themselves, the code development process brings together building pro-fessionals on a regular basis. It provides an international forum for discussion and deliberationabout building design, construction methods, safety, performance requirements, technol

15、ogicaladvances and innovative products.DevelopmentThis 2018 edition presents the code as originally issued, with changes reflected in the 2003 through2015 editions and further changes approved by the ICC Code Development Process through 2017. Anew edition such as this is promulgated every 3 years.Th

16、is code is founded on principles intended to mitigate the hazard from fires through the devel-opment of provisions that adequately protect public health, safety and welfare; provisions that donot unnecessarily increase construction costs; provisions that do not restrict the use of new materi-als, pr

17、oducts or methods of construction; and provisions that do not give preferential treatment toparticular types or classes of materials, products or methods of construction.iv 2018 INTERNATIONAL WILDLAND-URBAN INTERFACE CODEMaintenanceThe International Wildland-Urban Interface Code is kept up to date t

18、hrough the review of proposedchanges submitted by code enforcement officials, industry representatives, design professionalsand other interested parties. Proposed changes are carefully considered through an open codedevelopment process in which all interested and affected parties may participate.The

19、 ICC Code Development Process reflects principles of openness, transparency, balance, dueprocess and consensus, the principles embodied in OMB Circular A-119, which governs the federalgovernments use of private-sector standards. The ICC process is open to anyone; there is no cost toparticipate, and

20、people can participate without travel cost through the ICCs cloud-based app, cdp-Access. A broad cross section of interests are represented in the ICC Code Development Process.The codes, which are updated regularly, include safeguards that allow for emergency action whenrequired for health and safet

21、y reasons.In order to ensure that organizations with a direct and material interest in the codes have a voicein the process, the ICC has developed partnerships with key industry segments that support theICCs important public safety mission. Some code development committee members were nomi-nated by

22、the following industry partners and approved by the ICC Board: American Institute of Architects (AIA) International Association of Fire Chiefs (IAFC) National Association of Home Builders (NAHB) National Association of State Fire Marshals (NASFM)The code development committees evaluate and make reco

23、mmendations regarding proposedchanges to the codes. Their recommendations are then subject to public comment and council-widevotes. The ICCs governmental memberspublic safety officials who have no financial or businessinterest in the outcomecast the final votes on proposed changes.The contents of th

24、is work are subject to change through the code development cycles and by anygovernmental entity that enacts the code into law. For more information regarding the code devel-opment process, contact the Codes and Standards Development Department of the InternationalCode Council.While the I-Code develo

25、pment procedure is thorough and comprehensive, the ICC, its membersand those participating in the development of the codes disclaim any liability resulting from thepublication or use of the I-Codes, or from compliance or noncompliance with their provisions. TheICC does not have the power or authorit

26、y to police or enforce compliance with the contents of thiscode.Code Development Committee Responsibilities(Letter Designations in Front of Section Numbers)In each code development cycle, proposed changes to the code are considered at the CommitteeAction Hearing by the International Fire Code Develo

27、pment Committee, whose action constitutes arecommendation to the voting membership for final action on the proposed change. Proposedchanges to a code section that has a number beginning with a letter in brackets are considered by adifferent code development committee. For example, proposed changes t

28、o code sections or defini-tions that have BG in front of them (e.g., Section 202 BG DWELLING), are considered by the IBCGeneral Code Development Committee at the Committee Action Hearing.The content of sections in this code that begin with a letter designation is maintained by anothercode developmen

30、l Zoning Code Development Committee.For the development of the 2021 edition of the I-Codes, there will be two groups of code devel-opment committees and they will meet in separate years. Note that these are tentative groupings.Code change proposals submitted for code sections that have a letter desi

31、gnation in front ofthem will be heard by the respective committee responsible for such code sections. Because differ-ent committees hold code development hearings in different years, it is possible that some propos-als for this code will be heard by committees in both the 2018 (Group A) and the 2019

32、 (Group B)code development cycles.For instance, every section of Chapter 1 of this code is designated as the responsibility of theAdministrative Code Development Committee, and that committee is part of the Group B portion ofthe hearings. This committee will hold its code development hearings in 201

33、9 to consider all codechange proposals for Chapter 1 of this code and proposals for Chapter 1 of all I-Codes except theInternational Energy Conservation Code, International Residential Code and International GreenConstruction Code. Therefore, any proposals received for Chapter 1 of this code will be

34、 assigned tothe Administrative Code Development Committee for consideration in 2019.It is very important that anyone submitting code change proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

Deletion indicators in th

41、e form of an arrow ( ) are provided inthe margin where an entire section, paragraph, exception or table has been deleted or an item in alist of items or a table has been deleted.A single asterisk * placed in the margin indicates that text or a table has been relocated withinthe code.

The following table indicates suchrelocations in the 2018 edition of the International Wildland-Urban Interface Code.Coordination of the International CodesThe coor

43、dination of technical provisions is one of the strengths of the ICC family of model codes.The codes can be used as a complete set of complementary documents, which will provide userswith full integration and coordination of technical provisions. Individual codes can also be used insubsets or as stan

44、d-alone documents. To make sure that each individual code is as complete as pos-sible, some technical provisions that are relevant to more than one subject area are duplicated insome of the model codes. This allows users maximum flexibility in their application of the I-Codes.Italicized TermsSelecte

45、d terms set forth in Chapter 2, Definitions, are italicized where they appear in code text.Such terms are not italicized where the definition set forth in Chapter 2 does not impart theintended meaning in the use of the term. The terms selected have definitions that the user shouldread carefully to f

46、acilitate better understanding of the code.AdoptionThe International Code Council maintains a copyright in all of its codes and standards. Maintainingcopyright allows ICC to fund its mission through sales of books, in both print and electronic formats.The ICC welcomes adoption of its codes by jurisd
