29、 Services Work Clothing Elements2014 EditionThis edition of NFPA 1975, Standard on Emergency Services Work Clothing Elements, was pre-pared by the Technical Committee on Special Operations Protective Clothing and Equip-ment and released by the Technical Correlating Committee on Fire and Emergency Se
30、rvicesProtective Clothing and Equipment. It was issued by the Standards Council on November 12,2013, with an effective date of December 2, 2013, and supersedes all previous editions.This edition of NFPA 1975 was approved as an American National Standard on December2, 2013.Origin and Development of N
31、FPA 1975The Technical Committee on Protective Equipment for Fire Fighters began work onNFPA 1975 in 1982 in response to requests from the fire service to establish requirements forflame-resistant station uniform clothing. The first edition was acted on by the membership ofthe Association at the 1985
32、 Annual Meeting in Chicago, Illinois, and was issued with aneffective date of June 26, 1985.Following the 1985 edition, the name of the technical committee was changed to theTechnical Committee on Fire Service Protective Clothing and Equipment. Under the direc-tion of that technical committee, a sub
33、committee was formed to address station/work uni-form concerns. The Subcommittee on Station/Work Uniforms began revision of the 1985edition of NFPA 1975 in 1988, and the second edition was acted on by the membership of theAssociation at the 1990 Annual Meeting in San Antonio, Texas, and was issued w
34、ith an effec-tive date of August 17, 1990.The Subcommittee on Station/Work Uniforms began an early revision (four-year cycle) ofthe 1990 edition of NFPA 1975 in December 1991. During 1993, the NFPA restructured themanner in which committees were organized, and all standing subcommittees were elimi-n
35、ated. Within the Technical Committee on Fire Service Protective Clothing and Equipment,the former standing subcommittees were reorganized as task groups to address specific tech-nical issues, and the technical committee assumed the entire responsibility for NFPA 1975.The third edition of NFPA 1975 e
36、ncompassed revised scope and purpose sections to moreclearly identify what a station/work uniform is intended to be and that, because of the limiteddegree of protection it affords, it is not, of itself, a primary protective garment. However, astation/work uniform garment should not cause or contribu
37、te to injury from an unexpectedthermal exposure. The concept of “dual-purpose” station/work uniform garments that alsoare designed and certified as primary protective garments was introduced for situations in-cluding, but not limited to, wildland fire fighting or emergency medical services. Revision
38、s tocertain definitions also strengthened these areas. A new thermal shrinkage test for fabrics wasadded to the requirements. An increase of the pre-test conditioning by either washing ordry-cleaning was added to assure that treated flame-resistant fabrics will retain their flame-resistant character
39、istics over the expected life of the garment. The third edition was acted onby the membership of the Association at the Annual Meeting in San Francisco, California, onMay 18, 1994, and was issued with an effective date of August 5, 1994.In 1995, the NFPA Standards Council reorganized the entire proj
40、ect for fire service pro-tective clothing and equipment. The former single Technical Committee on Fire ServiceProtective Clothing and Equipment was disbanded and a new Project on Fire and EmergencyServices Protective Clothing and Equipment with a Technical Correlating Committee andeight technical co
41、mmittees operating within it was established. The responsibility forNFPA 1975 was assigned to the new Technical Committee on Special Operations ProtectiveClothing and Equipment.19751NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Q
42、uincy, Massachusetts 02169.The fourth edition included a major change whereby flame resistant garments were no longer required exclusively;garments were allowed to be made either from flame resistant fabrics or from cotton or wool fabrics. Flame resistanceperformance and testing was permitted to be
43、specified by the purchaser where desired and would be above theminimum requirements. The heat resistance and thermal shrinkage resistance requirements were retained. The heatresistance and thermal shrinkage resistance performance requirements were combined into a single requirement. Thechapter on ce
44、rtification was reformatted by moving product labels and user information into a new Chapter 3. A newChapter 4 on design requirements was also added.The 2004 edition of NFPA 1975 once again addressed the basic protection offered by these garments in non-emergency situations and the “user friendlines
45、s” of station/work uniform fabrics. The fifth edition included changesthat distinguished between thermally stable materials and materials that could potentially melt onto skin underconditions of accidental flame or high heat exposure, and provided for verification and certification of station/workun
46、iforms constructed from flame resistant fabrics.During the adoption process of the 1999 edition (fourth edition) of NFPA 1975, a floor amendment at the 1998 NFPAFall Meeting removed the requirements for flame resistant fabrics and the specified flame resistance test, and insteadpermitted nominally 1
47、00 percent cotton or nominally 100 percent wool fabrics to be used. This led to fabric thermal stabilityproblems, especially with wool fabrics but also with cotton fabrics that could cause or contribute to injury of the wearer.Because of the very nature of emergency services, emergency services pers
48、onnel can be exposed to unknown and unex-pected ignition sources during non-emergency situations when primary protective clothing is not being worn. Also, whenemergency services personnel are wearing station/work uniforms constructed from these fabrics under primary protectiveclothing, the possibili
49、ty of degradation of these fabrics exists and can lead to more severe injury for the wearer.In response to these problems, the Technical Committee on Special Operations Protective Clothing and Equip-ment incorporated new thermal stability performance requirements and a new thermal stability test in the fifth editionof NFPA 1975. In addition, the heat and thermal shrinkage resistance performance requirements and test method inthe 1999 edition were retained. The Committee also included optional criteria so that organizations that specifyflame-resistant fabrics for station/work unif
