A lone worker device is a portable safety device that automatically detects immobility, falls, or dangerous body positions and triggers an alarm without active intervention. It closes a critical safety gap: emergencies are reported even when the affected person can no longer make an emergency call themselves.
Lone working is common today in many industries – from maintenance and service to logistics, care, and facility management. Companies must ensure that employees are adequately protected even when out of earshot and sight.
The lone worker device can be implemented via different platforms: as a classic personal emergency signal system, as a smartphone solution with an emergency app, or as a smartwatch – adapted to risk, work environment, and organizational processes.
The classic personal emergency signal system remains the reference standard for high-risk workplaces. Devices like the Life Tel 2 are specifically designed for industrial use. They combine automatic triggers with an SOS button, pre-alarm, and acknowledgment. If the system detects prolonged immobility or a dangerous position, an alarm is automatically transmitted to stored recipients or a control center.
Commercially available smartphones can also be used as lone worker devices today. Advantage: The devices are already present in many companies. Mobi-Click also offers smartphones with a pre-installed lone worker app for immediate use.
Smartphone-based systems support pre-alarm, acknowledgment, and indoor positioning and are particularly suitable for mobile activities, field service, and service. Explosion-proof smartphones are available for hazardous areas.
The Life Watch is worn directly on the wrist – for particularly early and reliable detection of dangerous situations. Falls, immobility, and unusual body postures are continuously monitored and automatically trigger an alarm if necessary.
Its high everyday acceptance makes it ideal for care, facility management, building technology, and mobile service teams.
A lone worker device continuously monitors:
If a threshold is exceeded, a pre-alarm is first triggered, which can be acknowledged. If there is no response, the main alarm – including GPS or indoor positioning – is transmitted to colleagues or a control center.
Demand is focused on industries with elevated risks: fire departments, chemical, energy, construction, logistics, and maintenance in shafts and hazardous areas. In these environments, the man-down alarm is often the only reliable safeguard when employees become unconscious or incapacitated.
According to the Occupational Safety and Health Act, employers must assess risks and define appropriate measures. For hazardous lone work, personal emergency signal systems with a man-down function may be required. The choice – whether a classic PNA, smartphone, or smartwatch – must be based on the risk assessment according to DGUV 112-139.
What is a man-down alarm?A portable safety device that detects immobility, falls, or dangerous body positions and automatically triggers an alarm – even if the affected person can no longer act.
Is a smartphone sufficient as a man-down device?Smartphones with a man-down app are suitable for medium risks and mobile activities. For high-risk workplaces, a classic PNA like the Life Tel 2 is often recommended.
When is a classic PNA required?For activities with elevated risks, a dedicated PNA according to DGUV 112-139 is usually the safest solution.
