For your lone workers,
Guarantee optimal safety for your lone workers with Safeguard, a device capable of triggering real-time alerts and transmitting reliable information to enable emergency response in minutes.
PROTECTION
Why is lone worker protection crucial ?
Faced with the dangers of isolation, the French Labour Code imposes strict rules: "A lone worker must be able to signal any situation of distress and be rescued as quickly as possible." (under French Labour Code Article R4543-19). Indeed, every minute counts in the event of an incident.
Lone Worker Protection (LWP) is therefore a major safety challenge for companies and employers to guarantee the safety and peace of mind of their employees on a daily basis.

How does it work?
Detection
The lone worker device automatically detects incidents (man-down detection, immobility, fall) thanks to its sensors and intelligent algorithms.
Alert
Notifications are sent in a cascade to managers: this triggers the alert escalation chain.
Assistance and Response
A manager takes charge of the employee in distress. The information transmitted by the lone worker device (location, etc.) facilitates emergency response.
