This personnel safety device is designed to train the operator stay a safe distance to operate the vehicle. This add-on feature includes a low frequency magnetic field radiator (MF4) to the vehicle and a proximity receiver worn by the operator. This system is designed to detect when the distance between the operator and the vehicle gets too small for safe operation. It will first warn the operator and then may halt and shut down the vehicle if the dangerous condition persists. It substantially minimizes the risk of personal injury.
