Meant by lone worker protection is the protection of employees who work completely alone and not in close proximity to others, especially in dangerous environmental conditions, and who are protected by way of technical assistance. In the event of an emergency or an accident, an alarm can be sent to the control or rescue center by actively triggering an emergency switch (SOS button) on a mobile device or by means of special sensors (position/impact or motion sensor). In the case of mobile devices, LWP readiness usually takes place with the use of an app, via which the lone worker protection can be adjusted to the respective work situation.
