An apparatus for preventing impact to a person with an injury or infirmity includes a member that is worn over a portion of the body. Straps or other methods are used to secure the member where desired. The member provides a level of impact protection. The member can include optional cushioning material and a visible warning or audible warning, or both. The warning can be a written message or a well-recognized symbol, for example, a Red-Cross symbol. The written message or symbol or other portion of the apparatus can be illuminated, if desired. The illumination and audible warning can be constant or they can pulse on and off. A proximity sensor detects the approach of others and activates the visible and audible warnings. If desired, a command can then be spoken such as, "Stop! Do not approach!"
