A wedge for securing in an open position a hinged door having opposite faces and an edge between the faces. The wedge is luminescent and includes a bottom surface, a top surface at an acute angle to the bottom surface, and a pair of opposite side surfaces extending between the top and bottom surfaces. The wedge further includes an indentation on the bottom and each of the side surfaces sized to fully engage the door edge and make substantial contact with the door edge and the opposite faces. The wedge may be used to identify an entrance or exit to a room during no or low-light emergency conditions by using a UV light source to locate the luminescent wedge and location of the open door.

An emergency smoke filter for use by firefighters and the like has two stages: the first stage is a paper filter and the second stage is a charcoal filter. The emergency smoke filter is intended for use only in the event that a firefighters primary source of breathing clean air (a self-contained breathing apparatus or SCBA) malfunctions or runs out of air in a toxic, smoke filled environment. The emergency smoke filter does not replace an SCBA but augments it in case the SCBA is not working. The emergency smoke filter attaches to the firefighters SCBA in the slot for the regulator once the regulator is removed. The emergency smoke filter is intended for only one use and it can be deposed of thereafter.
