WA mining operations set up high tech lightning storm warning systems. If there's a possibility of a localised event, ln a timely manner, supervisors monitoring the storm instruct operations to cease, and all personnel to seek shelter. When the storm inevitably moves away, work promptly begins again. No self respecting employer would start and progress a project wherein employees could potentially face injury by not having lightning procedures in place. Should they not and there's a lightning incident - it's gonna be serious litigation time.
