A flat-fold, filtering, face-piece respirator that has a harness, a mask body, and first and second flanges. The mask body is capable of being folded flat for storage and can be opened into a cup-shaped configuration for use. The mask body has a filtering structure and has the first and second flanges disposed on first and second mask body sides. The first and second flanges project both laterally x and frontally y from the mask body. The provision of the flanges on each side of the respirator is beneficial to ease of mask donning, doffing, and adjustment, and to face fit and maintaining the open shape or configuration of the mask body.

Flat-fold respirator having flanges disposed on the mask body

A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member.

Respirator flow control apparatus and method

A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

The present disclosure is particularly adapted for determining whether the condition of personal protection equipment PPE articles satisfies at least one criterion. A method and system provide at least one predetermined criterion that governs use of the PPE article in a working environment; a PPE article is configured with a smart tag, and a sensing device is provided that is configured to sense data in a working environment related to the predetermined criterion. Acquired data from the sensing device and the smart tag are processed in a data processing system to determine whether the condition of the PPE article satisfies the at least one predetermined criterion.

Determining conditions of personal protection articles against at least one criterion

Stretched articles, such as oriented polymeric films or fibers, having microstructure features on at least one surface thereof, and processes for making such articles, are disclosed. A method of making fibers comprises forming a polymeric film having a body having a first surface and a second surface and having a longitudinal dimension. The film also comprises a plurality of elongate microstructure features disposed on the first surface of the body in a direction substantially parallel to the longitudinal dimension of the body, wherein the elongate microstructure features are substantially parallel. The method further comprises stretching the polymeric film in a direction substantially parallel to the longitudinal dimension of the body, and fibrillating the stretched polymeric film along the longitudinal dimension of the body to provide one or more fibers, wherein each fiber has at least one microstructure feature thereon.
