A device for use with a self contained breathing apparatus, such as a SCBA tank, which allows a user to display different indicia on the tank. The indicia are preferably illuminated by a self contained illumination system also located on the tank. The device allows a user to readily interchange the indicia so that the currently displayed indicia provide a specific message or indicate a specific condition to an individual observing the tank and related indicia. The illumination system permits the indicia on the tank to be clearly seen in poorly lighted environments, such as deep underwater, or in environments with poor visibility, such as in smoke-filled rooms associated with fires. |
