PRINTED IN THE U.S.A.2012 INTERNATIONAL FIRE CODE COMMENTARY iiiPREFACEThe principal purpose of the Commentary is to provide a basic volume of knowledge and facts relating
5、 to building construction as it pertains to the regulations set forth in the 2012 International Fire Code. The person who is serious about effectively design-ing, constructing and regulating buildings and structures will find the Commentary to be a reliable data source and reference to almost all co
6、mponents of the built environment.As a follow-up to the International Fire Code, we offer a companion document, the International Fire Code Commentary. The basic appeal of the Commentary is thus: it provides in a small package and at reasonable cost thorough coverage of many issues likely to be deal
7、t with when using the International Fire Code and then supplements that coverage with historical and technical background. Reference lists, information sources and bibliographies are also included.Throughout all of this, effort has been made to keep the vast quantity of material accessible and its m
8、ethod of presentation useful. With a comprehensive yet concise summary of each section, the Commentary provides a convenient reference for regula-tions applicable to the construction of buildings and structures. In the chapters that follow, discussions focus on the full meaning and implications of t
9、he code text. Guidelines suggest the most effective method of application, and the consequences of not adhering to the code text. Illustrations are provided to aid understanding; they do not necessarily illustrate the only methods of achieving code compliance.The format of the Commentary includes th
10、e full text of each section, table and figure in the code, followed immediately by the commentary applicable to that text. At the time of printing, the Commentary reflects the most up-to-date text of the 2012 Inter-national Fire Code. Each sections narrative includes a statement of its objective and
11、 intent, and usually includes a discussion about why the requirement commands the conditions set forth. Code text and commentary text are easily distinguished from each other. All code text is shown as it appears in the International Fire Code, and all commentary is indented below the code text and
12、begins with the symbol .Readers should note that the Commentary is to be used in conjunction with the International Fire Code and not as a substitute for the code. The Commentary is advisory only; the code official alone possesses the authority and responsibility for interpreting the code.Comments a
13、nd recommendations are encouraged, for through your input, we can improve future editions. Please direct your comments to the Codes and Standards Development Department at the Chicago District Office.The International Code Council would like to extend its thanks to the following individuals for thei

15、and its arrangement and format. The IFC, like other codes published by the International Code Council, is arranged and organized to follow sequential steps that generally occur during a plan review or inspection. The 2012 IFC has been reorganized into 7 Parts as illustrated in the tables below. Each
16、 Part represents a broad subject matter and includes the chapters that logically fit under the subject matter of each Part. It is also foreseeable that additional chapters will need to be added in the future as regulations for new processes or operations are developed. Accordingly, the reorganizatio
17、n was designed to accommodate such future chapters by providing reserved (unused) chapters in several of the Parts. This will allow the subject matter parts to be conveniently and logically expanded without requiring a major renumbering of the IFC chapters.2012 REORGANIZATION OF THE IFCParts and Cha
