• Tracking is not required by the system for it to be able to provide the location of a lone worker alert. All lone worker devices and apps update their location internally within the device and only transmit this information in the event of an alert activation. If a GPS position is not available when an alert is activated the last known GPS position will be automatically sent. The devices and app will also seek to update this position if a GPS fix becomes available while the alert is active. Certification that a lone worker cannot be tracked is available on request.

​

• Reliance on only a data connection in a lone worker device for alert facilities impacts heavily on the reliability of any lone worker system. All of the lone worker devices and apps incorporate the ability to first attempt delivery of alerts using a data connection but if this fails, will revert to delivery of the alert using SMS text messaging and voice call on selected devices/apps. This ensures the delivery of alerts even in very low signal areas.

​

• Incorporates a feature called Timed Personal Alerting (TPA). This feature allows users to activate Check-in Timers which if they expire, an alert is automatically generated. TPA’s can be activated using SMS text messaging or a via a smartphone app.

​

• Risk Level retrieval based on GPS coordinate. From within the SOS app a user can select the radius (default is 500m) for a Point of Interest and send this query to the PPS. Based on the users GPS coordinates the PPS will respond with details on the risk level and any other relevant information on each POI (Point of Interest) discovered.

​

• The responses provided to each user can be filtered based on criteria defined when the POI is created. This allows POI information that is only relevant to sections/departments to be given to them when requested e.g. Maintenance personnel may not need to know about chemicals that are stored at a different departments depot.
