Lone worker protection and fallback communication combined: How to remain capable of acting in crises

If standard communication fails, there is a risk of downtime and danger for employees. Companies, therefore, need a fail-safe communication tool that combines fallback communication and lone worker protection. Teamwire combines alerting with secure real-time messaging for greater security of supply and employee protection in any situation.

When the primary system fails

When large parts of the power grid in Spain and Portugal collapsed for hours in spring 2025, it wasn’t just the power supply that came to a standstill – communication between emergency teams was also severely restricted. Such incidents make this clear: 

 

Reliable communication solutions are essential for maintaining the ability to act effectively, even in crises. 

 

In the face of increasing geopolitical and environmental threats, the consistent establishment of highly redundant systems is crucial for strengthening the resilience of critical infrastructures and minimizing risks to employees

 

This is precisely where the interaction between fallback communication and lone worker protection comes in. Mobile employees in particular – whether they work for municipal utilities, energy suppliers, in fault clearance or care services – need a reliable, fail-safe communication tool at all times that protects them and secures operations at the same time.

 

Why fallback communication is essential

Critical infrastructures and many other organizations today rely on cloud-based standard solutions such as Microsoft Teams. But what happens when

  • cloud services are unavailable due to cyberattacks or outages?
  • the power fails, or central communication tools have a problem with the power supply (e.g., special servers)?
  • mobile networks are overloaded or disrupted?
  • communication in crisis scenarios takes place via insecure channels?

Without a fallback level, there is a risk of a standstill. Both in terms of employee safety and business continuity. A system is therefore required that functions independently of standard IT systems, reliably transmits alarms, and at the same time ensures real-time communication.

Lone worker protection – duty and responsibility

While major incidents attract public attention, another aspect often takes place in the background: the protection of employees who are traveling alone

 

In the energy sector, this is particularly applicable to fault clearance teams that inspect lines, check house connections, or work in high-risk areas. 

 

According to the German union IG Metall, almost a fifth of all employees work alone at times – a risk that the legislator has explicitly addressed:

 

The German accident prevention regulation “Principles of Prevention” (§ 25 BGV/GUV-V A1) obliges employers to ensure the safety of lone workers. This means that systems must be in place that can raise the alarm immediately in an emergency, transmit locations, and activate help chains

 

Teamwire supports exactly that. Our solution enables alarms, automatic location transmission, and the integration of escalation chains, allowing control centers or on-call services to respond immediately.

 

For employees, this means added security. For the organization, a reliable system that also creates legal certainty.

 

“Our IT department uses Teamwire’s broadcast function to quickly and specifically point out worst-case scenarios or current system failures. This means that all colleagues are informed immediately and misunderstandings are avoided.”

Fail-safe communication with Teamwire = alerting + real-time messaging

The decisive advantage of Teamwire lies in the combination of alerting mechanisms with a highly secure, reliable communication channel

Alarm messages reach all relevant people immediately, even if their devices are set to silent. Critical alarms and a panic button also allow automatic location transmission.

 

At the same time, the tool offers the possibility to share specific information with groups or via broadcast, to convey color-coded status messages for announcements and notes, and to highlight particular information or request feedback.

 

In the event of a malfunction, this protects employees on-site and ensures business continuity.

 

Push-to-talk facilitates quick coordination between teams. Live location and simple map functions create transparency about the situation in the network area. Video conferencing and augmented reality allow critical questions to be clarified directly. 

 

And because Teamwire is developed and hosted in Germany, all data remains sovereign, protected, and GDPR-compliant at all times. This is because our company and the servers of our partner IONOS are ISO 27001-certified and BSI C5-certified.

For these industries, fallback communication and lone worker protection are crucial

Practical experience shows that companies in critical industries, in particular, need communication systems that function reliably even under the most adverse conditions. A damaged substation, a large-scale power outage, extreme weather events such as flooding, and bomb disposal, among other factors, put people and networks under pressure. 

 

Employees need to be informed, protected, and coordinated – in real-time. Fallback communication and lone worker protection are therefore particularly relevant, for example, for

  • Energy suppliers and municipal utilities: Fault clearance teams must also be reliably alerted and coordinated in the event of power outages and grid failures.
  • Municipal services: Employees in building yards, wastewater companies, or social services are often out and about alone and must be reliably reachable.
  • Public safety and authorities: Emergency services in the field require a communication solution that can operate even in the event of IT failures.
  • Care and healthcare: Mobile care workers need security when they are out alone in private households.

“Teamwire enables us to communicate quickly, securely, and flexibly – both on a day-to-day basis and during extraordinary events such as bomb disposal or major events. We are particularly impressed by the intuitive operation, which can also be used by colleagues in pressurized situations.”

Resilience and fallback communication are more than just a “plan B”. They are a crucial building block for resilience, occupational safety, and business continuity, and go hand in hand: only if communication is also ensured in the event of a crisis, organizations will remain capable of acting, and employees will be protected.

FAQ: Frequently asked questions about lone worker protection and fallback communication

 

What is fallback communication?

Fallback communication refers to alternative communication channels that are immediately available if primary systems (e.g., cloud, mobile communications) fail.

Why is fallback communication important for critical infrastructure and mobile employees?

Because failures in the energy supply, healthcare, or public authorities can have serious consequences. Fallback communication ensures that communication also works in the event of a crisis.

How does Teamwire support lone worker protection?

Teamwire offers alarm functions, live-location, and secure group communication – all GDPR-compliant and ISO 27001-certified.

What distinguishes Teamwire from other communication solutions?

Teamwire combines alerting and real-time messaging, is fully hosted in Germany, ISO-certified, and specially developed for mission-critical and mobile communications.

Which industries benefit most from Teamwire and secure business messengers?

Energy suppliers, public utilities, care facilities, public authorities, and public safety benefit in particular, as mobile employees are deployed here and communication must be fail-safe and GDPR-compliant.
