1. A method for monitoring restricted areas below a temporarily elevated worker, the method comprising the steps of:
- elevating a wireless sensor system to an elevated location adjacent the worker that is temporarily positioned above ground level;
enabling the wireless sensor system to detect the presence of other personnel who enter a ground level restricted area below the wireless sensor system and the worker;
automatically alerting personnel who enter the restricted area in response to detection of the personnel by the wireless sensor;
lowering the wireless sensor system from the elevated location in response to the worker returning to ground level; and
disabling the wireless sensor system.

15. A system for monitoring restricted areas below a temporarily elevated worker, the system comprising:
-
a wireless sensor configured to detect the presence of personnel who enter a ground level, restricted area below the wireless sensor system when the wireless sensor is elevated to an elevated location adjacent the temporarily elevated worker; and a programmable processor configured to automatically adjust the predetermined size of the restricted area in response to changes in height of the elevated location.
