30、uipment and released by the Technical Correlating Committee on Fire and Emer-gency Services Protective Clothing and Equipment. It was issued by the Standards Council onNovember 27, 2012, with an effective date of December 17, 2012, and supersedes all previouseditions.This edition of NFPA 1981 was ap
31、proved as an American National Standard on Decem-ber 17, 2012.Origin and Development of NFPA 1981The first NFPA document to address fire fighter respiratory protection was NFPA 19B,Standard on Respiratory Protective Equipment for Fire Fighters. NFPA 19B was adopted on May 17,1971, at the Association
32、s Annual Meeting in San Francisco, California. It was developed bythe Sectional Committee on Protective Equipment for Fire Fighters of the Technical Commit-tee on Fire Department Equipment. After 1975, the Sectional Committee was removed fromthe Technical Committee on Fire Department Equipment and m
33、ade its own technical com-mittee. The main thrust of NFPA 19B was to prohibit filter-type canister masks for fire fightersand permit only self-contained breathing apparatus. NFPA 19B was officially withdrawn by theAssociation on May 19, 1981, at the Annual Meeting in Dallas, Texas.NFPA 1981, Standar
34、d on Self-Contained BreathingApparatus forFire Fighters, was adopted at thesame meeting to replace NFPA 19B. That first edition of NFPA 1981 essentially specifiedNIOSH/MSHA-approved SCBA with a minimum rated service life of 30 minutes. Open-circuit SCBA was required to be positive pressure.The Techn
35、ical Committee on Protective Equipment for Fire Fighters undertook a com-plete revision of NFPA 1981 to state performance requirements and appropriate testing pro-cedures designed to simulate various environmental conditions to which fire fighters SCBAcan be exposed during use and storage. These req
36、uirements are in addition to the basicNIOSH/MSHA certification requirements, and now NFPA 1981 applies to open-circuit SCBA.The second edition of NFPA 1981 was completed in March 1986 and adopted by theAssociation at the 1987 Annual Meeting in Cincinnati, Ohio.After the second edition, the name of t
37、he Technical Committee was changed to FireService Protective Clothing and Equipment, and a standing Subcommittee on Self-ContainedBreathing Apparatus was established.The third edition, in 1992, incorporated new requirements for third-party certificationand quality control, as well as a new total hea
38、t and flame test for the entire apparatus. Othertest methods covering facepiece lens abrasion and communications were revised.The third edition was completed in December 1991 and presented to the Association atthe 1992 Annual Meeting in New Orleans, Louisiana.In January 1995, the Standards Council r
39、eorganized the entire project for fire serviceprotective clothing and equipment. The new project was given a Technical Correlating Com-mittee on Fire and Emergency Services Protective Clothing and Equipment and seven tech-nical committees operating within the project. The former standing Subcommitte
40、e on Self-Contained Breathing Apparatus was changed to the new Technical Committee on RespiratoryProtection and Personal Alarm Equipment.The fourth edition, presented to the Association membership at the 1997 Annual Meetingin Los Angeles, California, incorporated new requirements for surrogate cylin
41、ders to replace19811NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.the actual breathing gas cylinders during the vibration testing to ensure a higher level of safety during this rigoroustest. A new requ
42、irement for redundant end-of-service-time indicators (EOSTI) was added to provide a better level ofsafety in case of failure of one end-of-service-time indicator.The fifth edition of NFPA 1981 was presented to the NFPA membership at the 2002 Annual Meeting in Minneapolis,Minnesota, on May 19, 2002.
43、That edition incorporated new requirements for heads-up displays (HUD) that provide visualinformation and warnings to SCBA wearers of the status of the SCBAs air supply and, where the HUD is powered by a powersource, the power source status. Those new requirements were in response to fire service re
44、quests for the provision ofuser-friendly information for SCBA wearers so they can better understand their environment and limitations.Also in response to strong fire service input to the Committee, new requirements were specified for a singleuniversal air connection located in a specific position on
45、 all new SCBA certified as compliant with the 2002 edition ofNFPA 1981, and existing SCBA that could be upgraded and certified as compliant with the 2002 edition of NFPA 1981.The RIC UAC RIC stands for rapid intervention company or crew (sometimes called RIT for rapid intervention team, orFAST compa
46、ny or crew); UAC stands for universal air connection permits the breathing air cylinder of an SCBA user tobe replenished from an independent rescue breathing air supply source when the SCBA user is trapped or unable tobe removed from a hazardous atmosphere. The RIC UAC does not take breathing air fr
47、om an SCBA being worn by amember of the rescue operation but replenishes the victims breathing air cylinder from a source of “rescue breathingair,” such as a rescue breathing air cylinder or a high-pressure breathing air supply line. The RIC UAC is not a “buddybreathing” device it does not permit th
48、e sharing of a single SCBA breathing air source between two persons. NIOSHdoes not permit or certify any buddy breathing system that allows two users to share a single breathing air source.Because NFPA 1981 requires NIOSH certification as a prerequisite to become certified as compliant with NFPA 198
49、1,NFPA cannot permit buddy breathing systems, which would be in violation of NIOSH regulations.The Committee continued to review and revise text for improved clarity and specificity, improved accuracy intesting and test result reporting, and added additional criteria to better evaluate and test the EOSTI.In 2002, NFPA revised the format for its codes and standards, resulting in chapter, section, and paragraph numbersnot matching or corresponding to those of previous editions.The 2007 edition of NFPA 1981, the sixth edition, represented a complete revision and retitling of
