A respirator cover or second-skin includes a support structure to cover a gas mask or respirator and is provided with cut-outs in the support structure to receive components of the respirator, the second-skin including an interior flexible gasket concentric and spaced from the outer perimeter of the second-skin which seals the cover to the outer surface of the respirator. The second skin serves to provide increased chemical protection to the user of a respirator, as an aid for garment interface, or to anchor a protective hood to the respirator.

Second-skin respirator cover

A material closure assembly including a material closure, such as zipper or a hook and loop fastener, having a first portion and a second portion that are configured to be releasably joined together; an electrical circuit that is configured to be closed when the first portion of the material closure is entirely joined with the second portion of the material closure; and an first indicator that is electrically connected to the electrical circuit and configured to indicate that the first portion of the material closure is entirely joined with the second portion of the material closure. The material closure assembly thus providing an active feedback system for closures on garments and personal protective equipment (PPE) to alert wearer of incomplete seals between interfaces on modular PPE which could result in the wearer of the PPE being exposed to the surrounding environment outside the PPE.

Advanced sealing-interface surveillance technology

A helmet mounted protective shroud apparatus for use with respirators includes a shroud mating component adapted to surround a respirator and a shroud component connected to the shroud mating component. The shroud component includes a fabric component having an edge, a plurality of connection mechanisms connected to the fabric component, and a flap component configured to cover a top of the fabric component, wherein the shroud component is adapted to cover a helmet and surround a wearer's head and neck. The present invention allows a chemical-biological protective hood/shroud assembly to be integrated for use with a helmet and respirator.

Helmet mounted protective shroud

A modular chemical/biological headgear system includes a helmet liner of a resilient shock absorbing material that conforms generally to the shape of a wearer's head, provides a cavity for removable installation of one or more modular filters in the back, and a duct to convey filtered air from the one or more modular filters to a face mask. The helmet liner may be equipped and configured with a variety of interchangeable modular components including hardened outer shells, communications modules, enhanced chemical biological filters, and the like, to meet a wide variety of operational needs.

Modular chemical/biological headgear system

Airflow is improved for multi-agent chemical biological air-purifying apparatus by providing a filter module that has multiple filter elements contained within a substantially sealed housing. The housing secures the filter elements in a spaced relation such that the top and bottom faces of each filter element are exposed to the flow of air and provides an air path within the housing adapted to channel air through the multiple filter elements in a parallel flow. The filter module may be made from a flexible and resilient plastic material and may be contoured to conform to the shape of a helmet liner or similar headgear.
