Abstract
Disclosed is a method and apparatus for selectively immobilizing equipment to ensure the safety of a proximate worker. The apparatus comprises an article of clothing wearable by the proximate worker, a sensor and a stopping means for stopping the movement of a portion of the equipment in response to the sensing. The article of clothing has a RFID tag having an antenna distributed about the article so as to substantially surround a worker wearing the article of clothing. The sensor senses the proximity of the RFID tag to a portion of the equipment. The method comprises sensing the proximity of the RFID tag to a portion of the equipment and stopping the movement of a portion of the equipment in response to the sensing.
