Significance and Use4.1 As with other hazardous materials protective ensembles, air-fed protective ensembles include clothing and equipment itemsneeded

39、for dermal and respiratory protection, including protective suits, gloves, footwear, and eye/face protection. Unlike otherprotective ensembles, air-fed protective ensembles do not use separate respiratory protective devices such as self-containedbreathing apparatus (SCBA) or non-powered air-purifyin

40、g respirators (APRs).(APRs).4.1.1 Those types of respirators normally have a tight fitting tight-fitting face piece that provides inhalation hazard protectionand dermal exposure protection to the face, eyes, nose, and mouth.4.1.2 Air-fed protective ensembles are worn without the use of a separate re

41、spirator. The entire suit serves as the respiratoryprotective device and also provides dermal exposure protection. The wearer breathes supplied air or filtered air pumped into theprotective suit.4.2 Air-fed protective ensembles are used to protect workers in a number of applications.4.2.1 These incl

46、nt.4.4 The qualification of the respiratory protective equipment is addressed by the applicable requirements for respiratorsestablished in 42 CFR Part 84. As such, the entire air-fed ensemble is subject to certification by NIOSH in addition to meeting therequirements in this specification.F2704 1734

47、.5 This specification establishes classifications for the protective ensemble. The classifications include one that is determinedby the configuration of the protective ensemble and one that concerns the use of the protective ensemble.4.5.1 A protective ensemble can be classified as aan “Airline Prot

48、ective Ensemble” or a “PAPR-Based Air-Fed ProtectiveEnsemble”.Ensemble.” Under each of these classifications, protective ensembles can be further classified as “Limited Use” and“Multiple-Use”.“Multiple Use.”4.5.2 These classifications account for differences in the configuration of the air supply an

49、d material strength and durability.These classifications do not account for the decontamination effectiveness of multiple use multiple-use ensembles.4.6 In recognition of the potential diverse applications to which the protective ensemble can be used, documentationrequirements are provided for manufacturers to base claims for permeation resistance of ensemble materials against specificchemicals or for claims of ensemble material performance against bloodborne (or liquidborne) pathogens.
