Lone-worker assistance

On huge mining sites, individual workers need to know they're backed by a support team, able to provide emergency assistance at a moment's notice.

At an open mine site, a single engineer is in the field, 10km from the central office. When he's injured by unexpected slope movement, unconscious and unable to call for help, a man-down device clipped to his belt activates an alarm. It signals to the monitoring centre after detecting he is no longer standing upright and has had no body movement for 30 seconds, prompting emergency assistance.
