An apparatus for identifying when an individual is in proximity to an object having a length has a sensor portion having a wire loop through which electric current runs and creates an electromagnetic field that emanates about the wire loop. The wire loop extending along at least a third of the length of the object. The apparatus has a personal alarm device that is worn by the individual which detects the presence of the magnetic field emanating from the wire loop when the personal alarm device is in the magnetic field and produces a signal indicating the personal alarm device is within the magnetic field. Alternatively, the sensor portion extends from a contiguous boundary up to 500 meters, where the boundary has a geometry that is linear or meandering. A head piece for an individual's head. A method for identifying when an individual is in proximity to an object. A field extension module. A proximity device.
