(Specification)Standard Specification for Air-Fed Protective Ensembles
Standard Specification for Air-Fed Protective Ensembles
SIGNIFICANCE AND USE
4.1 As with other hazardous materials protective ensembles, air-fed protective ensembles include clothing and equipment items needed for dermal and respiratory protection, including protective suits, gloves, footwear, and eye/face protection. Unlike other protective ensembles, air-fed protective ensembles do not use separate respiratory protective devices such as self-contained breathing apparatus (SCBA) or non-powered air-purifying respirators (APRs).
4.1.1 Those types of respirators normally have a tight-fitting face piece that provides inhalation hazard protection and 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 respirator. The entire suit serves as the respiratory protective device and also provides dermal exposure protection. The wearer breathes supplied air or filtered air pumped into the protective suit.
4.2 Air-fed protective ensembles are used to protect workers in a number of applications.
4.2.1 These include, but are not limited to: chemical and pharmaceutical manufacturing, remediation of hazardous materials sites, use against highly infectious biological agents in Biosafety Level 4 laboratories, and for protection of workers involved in nuclear and radiological facilities, where it is possible radioactive particles will be encountered.
4.3 The requirements of this specification have been partly based on the NFPA 1991 and NFPA 1994 standards, which establish criteria for vapor-protective ensembles used in hazardous materials emergencies. NFPA 1991 establishes requirements for a protective ensemble that encapsulates the wearer and the breathing apparatus. NFPA 1994 establishes requirements for a protective ensemble under Class 1 requirements that in some configurations encapsulates the wearer and the breathing apparatus.
4.3.1 In this specification, a breathing apparatus is not worn inside the suit, but instead breathing air is connected to the su...
SCOPE
1.1 This specification establishes design, performance, classification, documentation, labeling, and certification requirements for protective ensembles that deliver air to the wearer by means of an air line or powered air purifying respirator (PAPR).
1.2 As a prerequisite to this specification, regulations within Title 42 Federal Code of Regulations, Part 84 are used to establish the conformance of the air-fed protective ensemble to respiratory protection requirements.
1.3 This specification addresses protective ensembles used for environments involving chemical, biological, and radiological/nuclear particulate hazards.
1.4 This specification sets specific criteria for air-fed protective ensembles used to prevent exposure to substances such as, but not limited to, chemical hazards, infectious microorganisms requiring Biosafety Level 4 (BLS4) protection, and environments where it is possible radiological or nuclear particulates will be found.
1.5 This specification is further used for classification of the protective ensemble as limited use or multiple use.
1.6 The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
