Abstract: A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

Abstract: Filter assemblies are described. In particular, filter assemblies that include a filter frame, a fire resistant filter media, and a metallic layer disposed on and covering a major surface of the filter frame are described. The filter frame is rigid and includes at least one of a polymeric material, wood, or a wood pulp material. Filter assemblies described include flammable or meltable materials yet may retain structural integrity after being exposed to flame.

Abstract: A method for filtering airborne particulates is described. The method includes providing an exhaust hood, and the exhaust hood defines an intake and the exhaust hood being adapted to receive airborne particulates via the intake. The method also includes conveying a portion of a filter media from a media source area to an active media area, transferring the portion of the filter media from the active media area to a media discard area, the media discard area and the media source area being disposed on substantially opposed sides of the active media area, and severing the portion of the filter media in the media discard area from a remainder of the filter media.
