Significance and Use4.1 As with other hazardous materials protective ensembles,air-fed prote

31、ctive ensembles include clothing and equipmentitems needed for dermal and respiratory protection, includingprotective suits, gloves, footwear, and eye/face protection.Unlike other protective ensembles, air-fed protective en-sembles do not use separate respiratory protective devices suchas self-conta

32、ined breathing apparatus (SCBA) or non-poweredair-purifying respirators (APRs).4.1.1 Those types of respirators normally have a tight fittingface piece that provides inhalation hazard protection anddermal exposure protection to the face, eyes, nose, and mouth.4.1.2 Air-fed protective ensembles are w

33、orn without the useof a separate respirator. The entire suit serves as the respiratoryprotective device and also provides dermal exposure protec-tion. The wearer breathes supplied air or filtered air pumpedinto the protective suit.4Available from U.S. Government Printing Office Superintendent of Doc

36、 biological agents inBioSafety Level 4 laboratories, and for protection of workersinvolved in nuclear facilities, where it is possible radioactiveparticles will be encountered.4.3 The requirements of this specification have been partlybased on the NFPA 1991 Standard, which establishes criteriafor va

37、por-protective ensembles used in hazardous materialsemergencies. NFPA 1991 establishes requirements for a pro-tective ensemble that encapsulates the wearer and the breathingapparatus.4.3.1 In this specification, a breathing apparatus is not worninside the suit, but instead breathing air is connected

38、 to the suiteither via an external airline or respiratory protective equip-ment that is externally connected to the suit wall. Extensivecriteria for the integrity of the overall ensemble are appliedthrough design and performance criteria. This allows fordifferent configurations of a protective ensem

39、ble that incorpo-rates a hooded visor, protective gloves, protective footwear,and the respiratory protective equipment.4.4 The qualification of the respiratory protective equipmentis addressed by the applicable requirements for respiratorsestablished in 42 CFR Part 84. As such, the entire air-fedens

40、emble is subject to certification by NIOSH in addition tomeeting the requirements in this specification.4.5 This specification establishes classifications for the pro-tective ensemble. The classifications include one that is deter-mined by the configuration of the protective ensemble and onethat con

41、cerns the use of the protective ensemble.4.5.1 A protective ensemble can be classified as a “AirlineProtective Ensemble” or a “PAPR-Based Air-Fed ProtectiveEnsemble”. Under each of these classifications, protectiveensembles can be further classified as “Limited Use” and“Multiple-Use”.4.5.2 These cla

42、ssifications account for differences in theconfiguration of the air supply and material strength anddurability. These classifications do not account for the decon-tamination effectiveness of multiple use ensembles.4.6 In recognition of the potential diverse applications towhich the protective ensemb

43、le can be used, documentationrequirements are provided for manufacturers to base claims forpermeation resistance of ensemble materials against specificchemicals or for claims of ensemble material performanceagainst bloodborne (or liquidborne) pathogens. Similar re-quirements are established for the

44、respiratory protective equip-ment, when this equipment is based on the use of filters,cartridges, or canisters.4.7 An extensive section is provided in the specificationaddressing the certification of air-fed protective ensembles.This certification section is based on provisions established inNFPA 19

45、91 and other National Fire Protection Associationproduct standards for emergency services protective clothingand equipment.5. Classification5.1 Protective ensembles shall be classified as either an“Airline Protective Ensemble” or a “PAPR-Based Air-FedProtective Ensemble” depending on the type of res

46、piratoryprotective equipment that is provided with the ensemble.5.2 Protective ensembles shall additionally be classified aslimited use or multiple-use.5.2.1 Limited use protective clothing items shall be subjectto the labeling requirement in 12.6.1. Multiple-use garmentsshall be subject to addition

47、al conditions as part of testing asspecified in Sections 10 and 11, labeling requirements asspecified in 12.6.2, and technical information requirements asspecific in 14.1.6 and 14.1.7. In order to qualify as a multiple-use ensemble, all elements of the ensemble shall meet everyapplicable multiple-us

48、e requirement.5.3 All protective ensembles classified to this specificationshall meet the applicable design requirements specified inSection 6, performance requirements specified in Section 7,documentation requirements as specified in Section 8, appli-cable labeling requirements specified in Section
