The Lone Worker Protection app

Logo Safeguard

Reliable protection and responsive emergency assistance

Strengthen the protection of your lone workers with an intuitive mobile app

For those responsible for lone workers, the Lone Worker Protection app makes it possible to monitor, alert and respond in the event of an incident. It enables any manager included in the alert escalation chain to be notified quickly when an employee is in distress. Once the notification is received, incident-related information is transmitted so emergency services can respond quickly and effectively.

What is the Safeguard Lone Worker Protection app?

The Lone Worker Protection app turns a phone into a monitoring tool, enabling managers to look after the safety of their lone workers in real time. The app complements the Lone Worker Alarm Device / man-down alarm solution by offering:

The key features of Safeguard App: a Lone Worker Protection app for supervisors

Immediate alerting in the event of an incident

A real-time monitoring smartphone app

When an incident occurs, every second counts. The Lone Worker Protection smartphone app ensures maximum responsiveness through the instant transmission of alerts after the pre-alert.

Supervisors immediately receive the relevant information needed to trigger the appropriate procedures. This drastically reduces emergency response times.

The PTI Safeguard app by Sysnav enables real-time monitoring of potential accidents. Thanks to the app, a manager can be alerted anywhere, at any time, to a distress situation or an incident.

Information about the nature of the Lone Worker Protection alarm (fall, loss of verticality, loss of network coverage, etc.) is transmitted.

How does the Lone Worker Protection app work?

Launching an alert escalation chain

If an incident is detected, the Safeguard lone worker alarm device triggers an alert escalation chain with cascading notifications. The monitoring app then makes it possible to notify the appropriate manager in real time that a colleague is in distress.

Alarm handling by a manager

With the smartphone app, the supervisor has direct access to the incident information and the precise position of the employee in distress on a site map.

Fast emergency response

Thanks to precise location tracking, support can be provided as quickly as possible after detection, helping to limit the consequences of the accident for the worker’s health.

The app is therefore a real asset for managers, ensuring they are alerted as quickly and effectively as possible with the maximum amount of information.

A simple and intuitive interface on your smartphone

One of the strengths of the Lone Worker Protection app is its ergonomics, designed for field use and simple operation.

The interface is clear, easy to use and requires no complex training. Teams can therefore focus on their primary mission, using a tool that is not an additional burden but genuine support.

Centralised management of all alerts

The smartphone app does more than just relay alerts: it enables them to be monitored, managed and centralised.

At a glance, supervisors can access:

  • current alerts,
  • the status of lone workers,
  • event logs (falls, immobility, alarms, etc.)

This overall view provides an immediate understanding of the situation, essential for a rapid and coordinated response.

Customised alert escalation chains thanks to the Lone Worker Protection app

Safety managers can configure bespoke alert escalation chains, tailored to the organisation, the site and internal procedures. It becomes possible to define precisely: who receives the alert, in what order, and with which priority levels.

Greater responsiveness for managers and safety leads

  • Immediate decision-making
  • Organisation of a response
  • Real-time monitoring of incident handling


Result: a decisive gain in responsiveness, significantly improving operational safety.

FAQ - Lone Worker Protection

What is Lone Worker Protection (LWP)?

LWP (Lone Worker Protection) refers to all the devices and procedures put in place to ensure the safety of people working alone, without direct or immediate contact with a colleague or supervisor.
LWP also meets the employer’s legal obligation to protect the health and safety of lone workers, in accordance with the Labour Code.

A lone worker alarm device is a safety device used by lone workers to alert emergency services in the event of an incident. These systems can take the form of dedicated devices, safety belts or armbands, mobile applications, PTI watches or connected PPE.

LWP devices can come in different forms: a man-down belt, a lone worker device, an SOS alarm button, a mobile smartphone app, a watch or connected PPE. Each company will need to choose an alarm device in line with its needs and specific risks. 

Protecting lone workers is a legal obligation for the employer and the company. It stems from the general safety obligation set out in the Labour Code. The obligation to protect lone workers may also be found in the Civil Code and case law.
Beyond the legal aspect, lone worker protection enables an organisation or company to create a reassuring working environment. At Sysnav, to provide a suitable solution, we systematically prepare a customised quote. We support our clients by adapting the solution to their activity.
