In some examples, a system includes: a plurality of different articles of personal protection equipment (PPE) that are all controlled by a particular user, and a computing device. The computing device may include one or more computer processors configured to receive sets of data from each of the different articles of PPE, wherein each set of data is based at least in part on a type of each of the different articles of PPE; generate for display a user interface that contemporaneously includes a plurality of graphical elements that are based at least in part on at least two sets of data that correspond to at least two different articles of PPE of the plurality of different articles of PPE; and in response to receiving an indication of user input that corresponds to at least one of the plurality of graphical elements, perform at least one operation.

A respiratory protection circuit of the type having an air flow regulator disposed in an air flow path between an air supply and a respirator is improved by including an air flow splitter and a bi-directional valve. The air flow splitter is disposed in the air flow path upstream from the air flow regulator, the splitter dividing the air flow path into first and second downstream flow paths, with the first downstream flow path leading to the respirator. The bi-directional valve is disposed in the second downstream flow path wherein the bi-directional valve prevents excessive downstream air flow therethrough and prevents upstream air flow therethrough.

Respiratory system and method of use

A supplied air helmetcomprises a visorand a face sealthat is secured to the visor. The face sealincludes a sealing memberand a frame memberThe sealing memberextends radially inward from the frame memberand has first and second regions of permeabilityandThe second regionhas greater permeability than the first regionThe use of a face sealthat has differentiated permeability allows for a controlled flow of air through the interior of the supplied air helmet

The present invention relates to a fan-forced positive pressure breathing apparatus commonly known as a Powered Air Purifying Respirators (PAPR) system, and specifically concerns the connecting of the breathing components of such equipment. The invention is a method and apparatus for rapid engagement of PAPR breathing components (such as air supply lines and filter elements to a blower housing). The invention also provides for indicating and/or monitoring whether the relative components have been aligned and coupled in sealed engagement.
