Claim Text:
1. An emergency services system for a worksite comprising: a mesh communications network comprising a plurality of communication nodes distributed to enable communication over the worksite; a plurality of personal tags, each personal tag configured to be carried by or on a person, the tags being switchable between: an active state in which the tag is recognised by one or more of the nodes and uniquely identifies a person carrying the tag; and, an inactive state where the tag is not recognised by one or more of the nodes; the nodes enabled to communicate with active tags in the worksite and provide corresponding position data relating to the active tags; a management system configured to receive and process the position data of the active tags from one or more of the nodes via the mesh communications network, and comprising a three dimensional representation of the worksite enabled to provide real time indication of the location of each active tag and the location of each node within a prescribed distance of one meter or less; and the emergency services system is configured to detect presence of a person in the worksite without an active tag and, upon detection of such a person, raise an alarm.
