A WORKER PROTECTION METHOD

摘要

The present invention relates to a portable computational device for protecting at least one worker. The device is configured to send a protection request for allocation of a protection zone for at least one worker. The device is also configured to receive confirmation that the protection zone has been allocated. In one embodiment, the device is configured to both monitor the location of the worker relative to the protection zone and determine whether a hazard is co-incident with the protection zone.
