The ZoneSafe Proximity Warning System allows heavy equipment operators to receive automatic alerts if pedestrians or other personnel are close to the machinery and at risk. All yard personnel will wear a small RFID tag, which constantly transmits location signals that are picked up by antenna installed in the equipment.
The RFID technology was developed by U.K.-based Avonwood Developments. It is the first adaptation of RFID tags and transponders for use at a port facility. Installation cost $300,000.
