The users of NFPA Standards bear the sole responsibility for determining the validity of any such patent rights,
18、 as well as the risk of infringement of such rights, and the NFPA disclaims liability for the infringement of any patent resulting from the use of or reliance on NFPA Standards. NFPA adheres to the policy of the American National Standards Institute (ANSI) regarding the inclusion of patents in Ameri
19、can National Standards (“the ANSI Patent Policy”), and hereby gives the following notice pursuant to that policy: NOTICE: The users attention is called to the possibility that compliance with an NFPA Standard may require use of an invention covered by patent rights. NFPA takes no position as to the
20、validity of any such patent rights or as to whether such patent rights constitute or include essential patent claims under the ANSI Patent Policy. If, in connection with the ANSI Patent Policy, a patent holder has led a statement of willingness to grant licenses under these rights on reasonable and
21、nondiscriminatory terms and conditions to applicants desiring to obtain such a license, copies of such led statements can be obtained, on request, from NFPA. For further information, contact the NFPA at the address listed below. Law and Regulations Users of NFPA Standards should consult applicable f
22、ederal, state, and local laws and regulations. NFPA does not, by the publication of its codes, standards, recommended practices, and guides, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so. Copyrights NFPA Standards are copyr

30、ncy Response 2017 Edition This edition of NFPA 704, Standard System for the Identication of the Hazards of Materials for Emergency Response, was prepared by the Technical Committee on Classication and Properties of Hazardous Chemical Data. It was issued by the Standards Council on May 13, 2016, with
31、 an effective date of June 2, 2016, and supersedes all previous editions. This edition of NFPA 704 was approved as an American National Standard on June 2, 2016. Origin and Development of NFPA 704 Work on this standard originated in 1957. A great deal of the development work had been done by the NFP
32、A Sectional Committee on Classication, Labeling, and Properties of Flammable Liquids starting in 1952. Background data were published by the Association in its quarterly magazine in 1954, 1956, and 1958. The material in its present form was rst tentatively adopted in 1960. Ofcial adoption was secure
33、d in 1961, and revisions were adopted in 1964, 1966, 1969, 1975, 1980, and 1985. In the 1987 and 1990 editions, the Committee on Fire Hazards of Materials introduced quantitative guidelines for assigning the Health Hazard and Reactivity Hazard Ratings. The 1996 edition introduced additional quantita
34、tive guidelines and an amended denition for instability hazard rating, formerly reactivity hazard rating. The 2001 edition claried numerous topics, including the following: rating of mixtures; three options of how to rate areas with multiple chemical storage and use; location of signs; more quantita
35、tive criteria for ammability ratings for solids; and quantitative criteria for a ammability rating of zero, including introduction of a new test method. Guidance material was added for quantifying the degree of water reactivity. An annex was added to cover water reactivity and identication criteria,
36、 as well as additional information on ash point test methods. The 2007 edition claried numerous topics, including the special hazards quadrant and placement and hierarchy of symbols. The new simple asphyxiant (SA) designation and other optional symbols, as well as requirements for the classication o
37、f ammability rating for dusts, were added. The 2012 edition included reinstatement of the differential scanning calorimetry (DSC) hazard criterion to Table 7.2 as well as new guidance on the ammability hazard classication for aerosol products. The 2012 edition also included new text in Table 6.2 tha
38、t emphasized the use of Annex D to classify the ammability hazard of a nely divided solid. The 2016 edition has several key changes to text and added two explanatory annexes. Information related to differential scanning calorimetry (DSC) exotherm onset temperature criteria was removed from Table 7.2
39、. Chapter 8 was modied to require the use of the SA symbol for liqueed carbon dioxide vapor withdrawal systems and where large quantities of dry ice are used in conned areas since there is currently no way of warning of this hazard in the existing NFPA 704. A new Annex G explains key differences bet
40、ween the OSHA HazCom2012 and NFPA 704 and claries the reasons why the NFPA 704 rating system will remain unchanged by the implementation of HazCom2012.IDENTIFICATION OF THE HAZARDS OF MATERIALS FOR EMERGENCY RESPONSE 704-2 2017 Edition A new Annex H provides sample placards that can be extracted int
41、o emergency response publications and training materials to ensure consistency. The NFPA 704 Committee dedicates the 2017 edition to the memory of Dr. Arthur A. Krawetz, who had been a Committee member since 1979 and who died during active service to the Committee, in November 2015. He was founder a
42、nd president of Phoenix Chemical Laboratory, Inc., in Chicago, engaged in analysis, research, and development, including characterizing chemical and physical properties, and quantifying performance expectancy of a wide variety of commercially important substances: fuels, lubricants, hydraulic uids,
43、greases, coatings, petrochemicals, additives, solvents, and rust preventatives. On learning of his passing, Arthurs colleagues on the committee expressed appreciation of his wisdom, expertise, leadership, humor, assertiveness, and general ability to contribute to the fun part of meeting in person fo
44、r extended periods hence this heartfelt tribute to a man who will be missed.COMMITTEE PERSONNEL 704-3 2017 Edition Technical Committee on Classication and Properties of Hazardous Chemical Data Ron A.
