1994 Class 4R certifications specify these elements by make/model -- using any element other than those specified invalidates the certification. The elements of this Item should be purchased and used as a complete ensemble.

PAPR. Note that the certification applies to a specific set of elements identified by make/model (garment, gloves, boots, respirator) and the ensemble certification is void unless the specified elements are used (e.g., it is not permissible to substitute a respirator that have not been certified as part of the ensemble). Footwear certified to certain other standards (e.g., NFPA

1970) is acceptable if the footwear height is at least 8 inches when measured from the floor. NFPA

1994 Class 4R ensembles provided higher levels of physical hazard resistance and increased durability as compared to Class 4 ensembles.

The ensemble is designed to minimize the inward leakage of biological or radiological particulates only, verified by a particle-tight integrity test. The ensemble is also intended to minimize any exposure to airborne solid chemicals or dusts. The suit and component parts do not offer protection from gases, vapors, or aerosols. Limited liquid protection is offered, primarily to enable wet decontamination. Materials are tested for viral penetration resistance and various physical properties to ensure adequate high levels of durability and resistance to physical hazards for a single exposure (ensembles may be reused if not contaminated and free from damage). Ensembles are tested for functionality.

Operating Considerations: Class 4R ensembles are designed to protect emergency first responder personnel during hazardous materials emergencies and at terrorism incidents involving biological hazards or radiological particulate hazards where the concentrations are below Immediately Dangerous to Life or Health (IDLH) levels, permitting the use of air-purifying respirators (APR), or powered-air purifying respirators (PAPR) and the operational environmental includes physically demanding conditions.

Class 4R protective ensembles are intended for use in situations involving only biological or radiological particulates, where there is no threat for exposure to chemical warfare agents or toxic industrial chemicals. While Class 4 ensemble materials are evaluated for viral penetration resistance for protection against bloodborne pathogens (OSHA Title 29 CFR

Code of Federal Regulations

1910.1030), they should only be used when there is very little potential for liquid exposure. Class 4R ensembles must cover the individual; however, the respirator certified with the ensemble may cover the face of the wearer. Because these ensembles are intended for longer wearing periods, the use of air-purifying respirators or powered air-purifying respirators with these suits is likely. Use considerations are provided in OSHA Title 29 CFR
