All Rights Reserved. NFPA 170 Standard for Fire Safety and Emergency Symbols 2018 Edition This edition of N
29、FPA 170, Standard for Fire Safety and Emergency Symbols, was prepared by the Technical Committee on Fire Safety and Emergency Symbols. It was issued by the Standards Council on April 3, 2017, with an effective date of April 23, 2017, and supersedes all previous editions. This edition of NFPA 170 was
30、 approved as an American National Standard on April 23, 2017. Origin and Development of NFPA 170 The 1994 edition of NFPA 170 represented the completion of an effort to combine four previously separate documents that covered re safety symbols for different purposes. These documents were the followin
31、g: NFPA 171, Public Firesafety Symbols NFPA 172, Fire Protection Symbols for Architectural and Engineering Drawings NFPA 174, Fire Protection Symbols for Risk Analysis Diagrams NFPA 178, Symbols for Fire Fighting Operations The Technical Committee on Fire Safety Symbols believed that placing all re
32、safety symbols in one document made it easier for users of symbols to nd the one(s) most appropriate for their application. It also eliminated duplication between these and eventually other NFPA documents. The rst edition of NFPA 170, in 1991, placed these four documents in one document but did not
33、combine them, except for denitions that were in each document. For the second edition of NFPA 170, in 1994, the Technical Committee on Fire Safety Symbols completely restructured the text into a logical and cohesive arrangement. The duplication of symbols that occurred during the aforementioned cons
34、olidation of documents was eliminated. New symbols added included those for campre prohibitions, smoke barriers, illuminated exit signs, and belowground tanks. For the third (1996) edition of NFPA 170, changes included the following: (1) Upgrading recommendations on pre-incident planning to requirem
35、ents (2) Adding new symbols for pull station, area of refuge, and cooking prohibition (3) Clarifying the symbols for smoke detectors, battery-powered emergency lights, and re service/ emergency telephone station (4) Recognizing the phaseout of Halon now taking place and the introduction of clean age
36、nts The 1999 edition further recognized the introduction of clean agents by adding new symbols for clean agent and water mist systems. A new appendix (Appendix C) was added to include symbols that can be used for life safety planning. The 2002 edition was reformatted to conform to the Manual of Styl
37、e for NFPA Technical Committee Documents. Symbols for re alarm system components were added for consistency with NFPA 72 , National Fire Alarm Code . In 2004, the scope of the committee was expanded to include emergency symbols to allow emergency mapping symbols in a new Chapter 8. The 2006 edition
38、of NFPA 170 included the renement of exit symbology for better recognition of exit, arrow, and ame symbols that are consistent with international standards.FIRE SAFETY AND EMERGENCY SYMBOLS 170-2 2018 Edition A new Chapter 8, Symbology for Emergency Management Mapping, was added to assist the user i
39、n the preparation for, prevention of, protection against, response to, and recovery from threats to the nations population centers and critical infrastructure from terrorist, criminal, accidental, or natural origin. The symbols in Chapter 8 were the result of efforts by the Federal Geographic Data C
40、ommittee Homeland Security Working Group (http:/www.fgdc.gov/fgdc/homeland/index.html). The symbols were included in the 2006 edition so that they can be processed through an accredited standards-writing organization and made available to the public. The 2009 edition of NFPA 170 included a new chapt
41、er (Chapter 9) that provided guidance on the development of emergency evacuation diagrams and plans. The 2012 edition of NFPA 170 included a new Chapter 7 and a new Chapter 8, previously all encompassed within the old Chapter 6. This affected symbol detail for various device symbols such as re alarm
42、 devices, re sprinkler devices, electronic re and smoke detection, and so forth. This action better organized existing symbols within the standard for the user. The 2015 edition revised several symbols for consistency and clarity. The “wisp of smoke” was replaced by an “S” to simplify the symbol whe
43、n viewed on plans. Many tables were reorganized for clarity and ease of use as well. In the 2018 edition, the tornado symbol has been added, and several references have been updated. The term smoke barrier has been changed to smoke rated, and the term re barrier has been changed to re rated. More de
44、tails have been added to the symbols for a re department connection. A distinction has been made between water-driven and electric-driven water ow alarms.COMMITTEE PERSONNEL 170-3 2018 Edition Technical Committee on Fire Safety and Emergency Symbols James M.
