All Rights Reserved.NFPA1992Standard onLiquid SplashProtective Ensembles and Clothing forHazardous Materials Emergencies2012 EditionThis edition of NFPA 1992, Standard on Liquid SplashProtective Ensembles and Clothing for
26、Hazard-ous Materials Emergencies, was prepared by the Technical Committee on Hazardous Materials Pro-tective Clothing and Equipment (FAE-HAZ) and released by the Technical Correlating Commit-tee on Fire and Emergency Services Protective Clothing and Equipment (FAE-AAC). It was issuedby the Standards
27、 Council on December 13, 2011, with an effective date of January 2, 2012, andsupersedes all previous editions.This edition of NFPA 1992 was approved as an American National Standard on January 2, 2012.Origin and Development of NFPA 1992In 1985, the National Transportation Safety Board (NTSB) issued
28、report I-004-5 on ahazardous material incident that occurred in Benicia, California. In that report, the NTSBrecommended that standards be developed for protective clothing for protection from haz-ardous chemicals. The United States Department of Transportation (DOT) issued a positionthat requested
29、private sector standards development to undertake the project of writing thestandards on hazardous chemical protective clothing and asked other governmental agenciesto assist and participate in the private sector standards development system. The DOT at thattime also directly requested that NFPA dev
30、elop documents on hazardous chemical protectiveclothing. The Environmental Protection Agency (EPA), the United States Coast Guard(USCG), the Federal Emergency Management Agency (FEMA), and the Occupational Safetyand Health Administration (OSHA) either endorsed the DOT position or adopted positionsta
31、tements modeled after it.During 1985, the NFPA Standards Council approved a project for development of these stan-dards and assigned the project to the Technical Committee on Fire Service Protective Clothingand Equipment. The technical committee established a standing Subcommittee on HazardousChemic
32、als Protective Clothing, which began its work in Phoenix, Arizona, in March 1986. Repre-sentatives from USCG, FEMA, and OSHA participated on the subcommittee.At the same time, the American Society for Testing and Materials (ASTM) was developing adocument on a selection of chemicals for evaluating pr
33、otective clothing materials that wouldserve as one of several ASTM testing criteria that would be referenced in the NFPA standards.The subcommittee met several times over a 212-year period at different locations across thecountry and developed two standards, one for vapor-protective ensembles and on
34、e for liquidsplashprotective ensembles and clothing.NFPA 1991 addresses vapor-protective ensembles designed to protect emergency responsepersonnel against exposure to specified chemicals in vapor and liquid splash environmentsduring hazardous materials emergencies. Chemical permeation resistance doc
35、umentation isrequired for primary suit materials (i.e., garment, visor, gloves, and boots) against eachchemical in the NFPA battery of chemicals and any additional chemicals or specific chemicalmixtures for which the manufacturer is certifying the suit. The NFPA battery of chemicalsconsists of 21 ch
36、emicals, which are specified in ASTM F 1001, Standard Guide for Chemicals toEvaluate Protective Clothing Materials. These chemicals were selected because they represent theclasses of chemicals encountered during hazardous chemical emergencies.NFPA 1991 includes performance requirements that were est
37、ablished to reflect simulated-use conditions. A suit pressurization test is used to check the airtight integrity of each protec-tive suit. Also, an overall suit water penetration test is designed to ensure the suit provides fullbody protection against liquid splashes. Primary suit materials must res
38、ist permeation for1 hour or more by each chemical in the NFPA battery. Manufacturers can certify protectivesuits for additional chemicals when the same permeation performance is met. Also includedin NFPA 1991 are penetration resistance testing of closures and leak and cracking pressuretests for exha
39、ust valves. These tests allow determination of adequate suit component perfor-mance in hazardous chemical environments.19921NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.Material testing for burst stre
40、ngth, tear strength, abrasion resistance, flammability resistance, cold temperatureperformance, and flexural fatigue are required so that materials used for vapor-protective suits will afford adequateprotection in the environment in which they will be used.NFPA 1992, Liquid SplashProtective Ensemble
41、s and Clothing for Hazardous Materials Emergencies, addresses liquid splashprotective ensembles and clothing designed to protect emergency response personnel against exposure to specified chemi-cals in liquid splash environments during hazardous materials emergencies. Documentation is required for c
42、hemical pen-etration resistance of garment material against an NFPA battery of test chemicals and any additional chemicals or specificchemical mixtures for which the manufacturer is certifying the suit. The NFPA battery of chemicals was selected from ASTMF 1001, Standard Guide for Chemicals to Evalu
43、ate Protective Clothing Materials. These chemicals do not include liquid chemicalswith known or suspected carcinogenicity or skin toxicity because these garments deal with skin exposure and not inhalation.This criterion produces a different subset of ASTM F 1001 chemicals to be certified.This standa
44、rd includes performance requirements that were established to reflect simulated-use conditions. Anoverall suit water penetration test is included to ensure that the suit provides full-body splash protection. Materialstesting includes burst strength, tear resistance, flammability resistance testing,
45、abrasion resistance, cold temperatureperformance, and flexural fatigue testing. These tests are required so that garment materials will provide adequateprotection in the environment in which they will be used.The first edition of NFPA 1992 was voted on by the Association at the 1989 Fall Meeting in
46、Seattle, Washington, onNovember 15, 1989, and had an effective date of February 5, 1990.The Subcommittee on Hazardous Chemicals Protective Clothing began an early revision (4-year cycle) of the 1990edition of NFPA 1992 in December 1991. During 1993, the NFPA restructured the manner in which committe
47、es wereorganized, and all standing subcommittees were eliminated. Within the Technical Committee on Fire Service Protec-tive Clothing and Equipment, the former standing subcommittees were reorganized as task groups to address specifictechnical issues, and the technical committee assumed the entire r
48、esponsibility for NFPA 1992.The 1994 edition of NFPA 1992 encompassed revised scope and purpose sections to include optional components forenhanced protection and replacement items. Test methods were updated and refined to better ensure repeatability oftesting results. Extensive changes were made to
49、 the product labels to better accommodate the optional and replacementitems.The 1994 edition was acted on by the membership of the Association at the NFPAAnnual Meeting in San Francisco,California, on May 18, 1994, and was issued with an effective date of August 5, 1994.In January 1995, the entire project for fire service protective clothing and equipment was reorganized by theStandards Council. The new project had a Technical Correlating Committee on Fire and Emergency Services Protec-tive Clothing and Equipment and
