In the public sector, field workers, including maintenance staff, technicians, social workers and reception staff, often work alone in isolated or potentially hazardous environments. This situation raises major safety concerns. In the event of an accident, medical emergency or assault, a rapid response and the ability to locate the person are essential. This is where Nomadia Protect comes in, a PTI/DATI solution designed to meet the specific needs of public-sector field workers.

What Is Lone Working? The Legal Framework According to INRS

The INRS points out that, although there is no strict legal definition of lone working, it is the employer’s responsibility, in this case the public-sector organization, to identify it as part of the risk assessment process.

Under Article L. 4121-1 of the French Labor Code, employers must take “all necessary measures” to ensure the safety and protect the health of workers. This includes assessing situations involving lone working.

As part of this process, emergency response procedures must be established. Implementing a DATI device may form part of these measures when justified by the risk assessment. In other words, lone worker protection (PTI) is not merely an option. It is a key prevention and regulatory compliance measure for public-sector employers.

Why a PTI/DATI Device Is Essential for Field Workers

1. Faster emergency response

With a well-designed DATI solution, such as Nomadia Protect, workers can trigger a manual alert using an SOS button or an automatic alert in the event of a fall or prolonged inactivity. This enables them to receive assistance quickly.

2. Precise geolocation

Nomadia Protect can locate workers in real time using GPS, the cellular network and other sensors. This is essential for enabling emergency responders to intervene effectively.

3. Different alert modes

A lone worker can send a discreet alert, for example via a connected watch, if they feel threatened. They can also trigger a conventional emergency alert using their smartphone.

4. Positive safety

Nomadia Protect includes a “presumption of danger” mode. If the connection is lost or the worker fails to respond to a periodic safety check, an alert can be triggered automatically.

5. Centralized alert management

Alerts can be handled internally by a supervision team or outsourced to a 24/7 remote monitoring center, depending on the requirements and resources of the local authority or public-sector organization.

Nomadia Protect: A PTI/DATI Solution Ideally Suited to the Public Sector

Nomadia Protect was specifically developed to address the challenges faced by mobile field teams, including technicians, maintenance staff and social workers. It combines the benefits of a mobile application with those of a centralized administration platform.

Ease of use: deployed on workers’ smartphones or connected watches, Nomadia Protect avoids the need to purchase costly dedicated equipment.
Automatic detection: using intelligent algorithms, the application detects risky situations such as falls or prolonged inactivity, even when the worker is unable to trigger an alert themselves.
Administration interface: field managers have access to a web-based dashboard to configure alert scenarios, monitor workers in real time and manage interventions.
PTI/DATI watch: for roles where smartphones are impractical, Nomadia offers a watch-based version that remains on the worker’s wrist, with GPS tracking and configurable alerts.
Remote monitoring center: as an optional service, the solution can rely on an external 24/7 monitoring center to receive and respond to alerts.

Real-World Examples in the Public Sector

Isère Department: 1,000 employees, including social workers and technicians, are protected by Nomadia Protect. The solution helps them report critical situations and be located when an alert is triggered.
DGFiP, the French Directorate General of Public Finances: 10,000 field employees, including inspectors, bailiffs and surveyors, use Nomadia Protect. Their smartphones become DATI devices capable of triggering an emergency response when necessary.
ADMR network: 450 isolated home-care workers are protected with Nomadia Protect, with centralized alarm management through a remote monitoring service.
Circet: 500 field technicians working in fiber and telecommunications are equipped with the solution. Nomadia Protect detects falls and prolonged inactivity, enabling rapid intervention while supporting regulatory compliance and worker safety.

Regulatory Compliance: PTI/DATI and Legal Obligations

Implementing a PTI/DATI solution such as Nomadia Protect helps public-sector employers meet their legal obligations:

The risk assessment document, known in France as the DUERP, must include lone-working situations.
Emergency response procedures must be defined, with protocols adapted to lone working.
The French Labor Code requires lone workers to be able to report any distress situation and receive assistance as quickly as possible.
The INRS emphasizes the need for a comprehensive approach. Providing a DATI device alone is not enough. Organizations must also introduce appropriate procedures, train their employees and ensure that emergency services have the necessary information.

Tangible Benefits for Field Workers and Public Administrations

1. Enhanced safety

Workers know that they can trigger an alert within seconds or that automatic detection will intervene if they become unable to do so. This reduces the anxiety associated with working alone.

2. Greater trust and improved job appeal

Having a PTI/DATI solution such as Nomadia Protect can strengthen workers’ sense of recognition and belonging, highlight the importance of their work and improve employee retention.

3. Faster response and improved traceability

Managers can monitor alerts in real time, analyze incidents, improve intervention procedures and use feedback from previous events to strengthen their processes.

4. Compliance and accountability

As a public-sector employer, the local authority or institution demonstrates that it takes employee safety seriously, complies with regulatory obligations and reduces legal risks.

5. Operational flexibility

Thanks to Nomadia Protect’s flexibility, including smartphone, watch, remote assistance and internal alert management options, each public-sector organization can configure the solution according to its size, resources and operational constraints.

Conclusion: Nomadia Protect, a Strategic Asset for the Public Sector

For public-sector organizations, protecting lone field workers is not merely a regulatory requirement. It is a human, operational and strategic priority.

Nomadia Protect provides a comprehensive, modern and practical solution:

It is a PTI/DATI solution aligned with best practices and legal requirements.
