A system and method for managing jobsite personnel is presented. An application registers Wi-Fi enabled mobile devices on a geographically-defined jobsite, associates them with individual workers, and associates the workers' devices with the particular jobsite. The application logs registered devices when the devices come within the physical boundaries of the associated jobsite. An administrator may receive reports on all registered mobile devices. In an emergency requiring jobsite evacuation, a server communicates to each logged mobile device a message requiring time-sensitive compliance. Compliance is tracked and recorded. The server can provide to the administrator one or more compliance reports.
