A high-risk worker such as a crane operator has a fever, or has an anomalous heartbeat (too low or high), the system sends an automated alert to his supervisor that this particular worker has a health issue which needs to be investigated.
A worker feels uneasy during course of his work. An alert is sent to the worker's supervisor - if he presses the SoS button, if he trips and falls (fall detection) or if he has an accident and faints (immobility trigger). In normal operation, every 10 minutes the device sends the data on heart rate, body skin temperature and the last known proximity.
A particular area in the plant is restricted access and hence, a BLE beacon is placed there. If an unauthorised worker enters that area, an alert is sent to the supervisor.
