A lone worker alarm is the device a lone worker carries to raise an alert after a fall, a medical emergency or an assault, manually or automatically. There are seven main families: smartphone app, smartwatch, dedicated device, panic button, satellite messenger, two-way radio and ATEX-certified equipment. The right choice depends on network coverage, the work environment and the main risk.


A Personal Safety Alarm (PSA) is the device that detects the incident and sends the alert: a smartphone with an app, a smartwatch, a dedicated device or a satellite messenger. It raises a distress alert manually (SOS button) or automatically (fall, immobility, loss of verticality), together with the worker's location.
Protecting lone workers benefits the whole organisation. An employee equipped with an alert device feels safe and stays focused on the job. The company shows it has put the necessary measures in place, which supports both compliance and its employer brand. And a personal safety alarm lets you respond faster to an accident and limit its consequences.








The budget for a lone worker solution depends on three factors: the software subscription, the hardware, and the 24/7 remote monitoring option.
