Saves Lives - Protects health

Zentnl saves lives

Zentnl’s digital safety net combines an effective lone worker alarm with analysis of alarm data, giving operations management and HSE a fact-based foundation for systematic work environment management. Alarm times and alarm sensitivity can easily be adapted to different work environments, job roles, and individuals.

Zentnl protects health

Data-driven ergonomics management is based on the fact that physical strain is not visible in a single “moment” but develops as patterns over time. When strain is monitored continuously, everyone gets the same clear picture. Ergonomics then becomes something that can be managed and improved in daily work, not just assessed from time to time.

Frequently Asked Questions

Why Zentnl?

The number of lone workers is increasing. When something happens to a lone worker, the time to first action is critical. Long-term sick leave due to strain injuries in the neck, shoulders and back, as well as exposure to vibration, is very costly for individuals, companies and society – and causes significant suffering for those affected. Zentnl was developed to address these challenges.

What is Zentnl?

Zentnl is a safety system for demanding work environments. It provides real-time support for lone working and also helps monitor strain, ergonomics, and vibrations. By collecting data automatically and making it easy to understand, Zentnl helps companies prevent injuries, reduce sick leave, comply with requirements and standards, reduce production loss over time, and increase productivity.

Why should we use Zentnl?

Zentnl reduces the time from incident to action and provides clear support in meeting legal health and safety requirements for high-risk lone work. Continuous ergonomics and workload reporting also gives you a fact-based picture of how work affecs the body over time, making it easier and faster to carry out risk assessments.

Who is Zentnl for?

Zentnl is designed for people working in demanding industrial environments and across dispersed sites – for example in energy, mining, construction, infrastructure and process industry. Typical users include workers, supervisors, control room/operations staff and HSE/health and safety managers.

Are there different Zentnl versions for different needs?

Yes. Zentnl-LWP (Lone Worker Protection) is aimed primarily at lone workers and the alarm chains around them, while Zentnl-HEALTH focuses on measuring and following up workload, ergonomics and exposures. Both packages can be implemented separately or together, and then scaled up as you expand usage.

How does Zentnl LWP – Lone Worker Protection work?

The system monitors falls and immobility based on defined thresholds. When an incident occurs, an automatic alarm is triggered to a predefined alarm group, supplemented with GPS location. Alarm times and thresholds can be adapted – in consultation with WAVR – depending on work environment, role and individual.

How does Zentnl HEALTH work?

The sensors record how the body is loaded during the work shift, for example time in awkward postures, repetitive movements, vibration or other defined exposure patterns. After the shift, the wearer receives simple feedback, such as a green/yellow/red assessment of the day’s load. In the portal, HSE receives aggregated statistics and reports for follow-up and decision-making.

How do we get started with Zentnl as a new customer?

Together with Zentnl you choose the package and scope, define roles ( and alarm chains if LWP ), and decide which sites or groups will start first. This is followed by portal setup, training of key roles and a short evaluation of the technology. Once the evaluation group is running well, you can scale further in the organisation.

What are the requirements for equipment and IT environment?

Zentnl shirts comply with relevant ISO standards for protective clothing (for example high visibility and heat/arc protection where required), and the mobile app runs on standard Android and iPhone smartphones. The portal is web-based.

How are privacy, security and data handled?

Personal privacy and data security are central in Zentnl. Only authorised roles can see individual data, all communication is encrypted, and alarm and exposure data is stored in a structured way for follow-up and audit.
