April 28: World Day for Safety and Health at Work

28 April 2025 marks World Day for Safety and Health at Work, which was established by the International Labor Organization (ILO) in 1984. In this context, Suva encourages companies to strengthen their prevention culture.

To mark World Day for Safety and Health at Work, Suva is calling for a strengthening of the prevention culture in companies. (Image: zVg / Suva)

According to the International Labor Organization (ILO), almost 3 million people worldwide die at work every year - an increase of over 12 percent compared to 2000. Most of these deaths are due to occupational diseases.

Deaths in Switzerland significantly lower compared to the rest of the world

According to statistics, deaths from occupational diseases are also higher than deaths from accidents at work in Switzerland. Between 2019 and 2023, around 218 employees died each year as a result of their work, 153 of these deaths were due to occupational diseases. The proportion of these deaths due to occupational diseases (70%) is well below the global average. It is also worth noting that 90 percent of deaths from occupational diseases in Switzerland are attributable to asbestos.

The culture of prevention: a cornerstone of health and safety in the workplace

On the occasion of World Day for Safety and Health at Work on April 28, 2025, Suva reminds us that the vital rules and checklists are still part of the basics of accident prevention. At the same time, however, the integration of a strong, evolving prevention culture that is practiced by all stakeholders must be further promoted.
For Suva, this requires six dimensions: Communication, values & rules, leadership, learning, responsibility and operational organization.

In order to master the current challenges in the area of occupational safety, health protection and leisure safety, it is important to integrate this prevention approach into everyday working life. "A strong prevention culture can be recognized by the fact that safe and healthy working is a matter of course for the company and its employees," reminds Heinz Waldmann, occupational safety/health protection expert at Suva.

After all, a strong prevention culture not only helps to significantly reduce accidents and absences, but also helps to improve performance, efficiency, the quality of work and the image and reputation of the company. According to Suva, a culture of prevention is therefore an important investment in the company and its employees.

From 11 to 14 March 2025, experts from all over the world gathered in Lyon for the 22nd edition of the International Metrology Congress (CIM2025), organized by the Collège Français de Métrologie (CFM). The event was held as part of the Global Industrie trade fair and once again demonstrated its central importance for science and industry in the field of metrology.

150 years of the Meter Convention - an anniversary edition

The year 2025 marked a special highlight: the 150th anniversary of the Metre Convention, a milestone in international cooperation in metrology. In his speech, Martin Milton, Director of the BIPM and President of CIM2025, paid tribute to this occasion with the words: "We are celebrating 150 years of the Metre Convention - it is the basis for measurements for all nations." This emphasized the fundamental role of metrology for science, industry and society.

Growing international resonance

With around 500 participants from 40 countries, the scope of the congress was clearly demonstrated. Current topics such as the digitalization of measurement technology, artificial intelligence and sustainability were discussed intensively in a total of 180 lectures and poster presentations. New formats such as the QI Digital Atelier and a short seminar on ISO/IEC 17025 also enriched the program.

Bridge between science and industry

A central element of the congress was the "Metrology Village" - a 1,000 square meter exhibition area where 60 companies presented their innovations. The close connection to industry was also reflected in the opening, where Thomas Courbe (DGE), Laurent Labatut (Trescal) and Cosimi Corleto (CFM), among others, took to the stage. The latter emphasized: "Cooperation between metrology and industry is essential for technological progress."

Voices from the experts

The scientific exchange and the international atmosphere were particularly appreciated by the participants. Andrea Giura (INRiM), awarded for the best poster presentation, emphasized: "It was fascinating to see how different fields of metrology interact and enable technological advances." Pauline Lemaire (MERSEN) praised the organization and the diversity of the audience: "The international community was strongly represented, the environment was open and collegial."

For young scientists such as Térence Bordet (COLAS), winner of the prize for the best presentation, the congress was a valuable platform: "This award motivates us to push our research further."

A successful milestone

With over 45,000 visitors to the Global Industry trade fair, an increase of 20 % compared to 2023, the relevance of CIM was once again underlined. The congress offered a unique space for knowledge transfer, networking and the promotion of joint innovation dynamics. The next edition of the International Metrology Congress CIM will take place in 2027.

Contract management as an Achilles' heel in companies?

Contracts form the legal framework that every company needs in order to be able to plan and operate reliably in the long term. It is therefore all the more surprising that even larger SMEs often do not yet have a digital contract management system.

With software-supported contract management, all affected employees are always up to date on the status of all contracts - and the resulting obligations and changes. (Image: istock-PrathanChorruangsak)

Contracts are the legal basis of every company and comprise a large number of agreements, such as purchase, rental or license agreements. Despite their importance, many medium-sized companies in Switzerland still do not have a digital contract management system. According to Dr. Pascal Habegger, Managing Director of Fabasoft 4teamwork AG, the management of contracts is often spread across different departments, which leads to confusing responsibilities and risks such as missed deadlines or contractual penalties. An intelligent software solution for contract management offers a remedy here.

Use of artificial intelligence

Digitization makes it possible to store all contracts in a central location and make them accessible to authorized persons at any time. This saves time, reduces duplicates and ensures complete traceability thanks to functions such as contract versioning. Companies can also use artificial intelligence (AI) to quickly implement regulatory changes and minimize risks without having to manually review every contract. AI-based systems analyze contracts automatically and initiate necessary changes or approval processes.

Digital signature for mobile working

Another highlight of modern contract management software is the option of digital signatures. These are forgery-proof and legally binding, which makes it easier for employees to be mobile and ensures that contracts can also be signed when working from home or on the move. In addition, integrated deadline management offers automatic reminders of important dates and deadlines, which in turn helps to reduce business risks and make the most of opportunities.

Overall, it is clear that digital contract management not only enables efficiency gains, but also strengthens a company's legal and operational security. Companies that do without these solutions run the risk of overlooking important obligations and suffering considerable financial or legal disadvantages as a result.

A day in the life of a data center team

Data center teams work behind the scenes, but are critical to the smooth functioning of an increasingly connected world. Juniper Networks, a leading provider of secure AI-native networking platforms, sheds light on the typical workday of a data center specialist in today's world.

The work of data center teams is increasingly being supported by AI. (Image: Depositphotos.com)

In large organizations ranging from financial service providers to manufacturing companies, data centre specialists are responsible for maintaining critical infrastructures. They can lead to significant losses in the event of a failure, as two examples show. If a stock exchange experiences latency problems during peak trading hours, this can have an impact on potential transactions worth billions. And a failed logistics system can interrupt the supply chain and trading for several days.

Avoiding such scenarios - whether by preventing outages or quickly rectifying faults - is one of the central tasks of those responsible for network infrastructures. They are also confronted with an evolving IT landscape in which traditional network expertise must merge seamlessly with the latest AI and cloud technologies.

Everyday life of data center teams

A typical day for a data center specialist begins with proactive system health checks, which used to take hours to perform manually but are now more efficient thanks to the use of AI-powered diagnostic tools. Over the course of the day, these specialists then take on various tasks within a framework that covers the data center lifecycle, so to speak. These include

  • Day 0 planning: The network experts design network topologies, define test procedures and create designs for a scalable infrastructure. An important tool here is the use of digital twins - virtual replicas of the production network that enable comprehensive simulation and optimization. By using digital twins, architects can explore what-if scenarios and test changes, capacity expansions or the integration of AI workloads without jeopardizing the stability of the live environment. This approach ensures that the architecture is not only robust, but also adaptable to support the innovations of tomorrow.
  • Day 1 implementation: During the deployment phase, for example, switches are connected, configurations are implemented and tests are carried out. Every connection is checked, every configuration is validated and every system is tested and balanced under load to ensure flawless operation.
  • Day-2+-Operations: In data centre management, the teams ensure high performance through continuous monitoring, rapid response to anomalies and proactive optimization. They use automation for routine tasks and focus their expertise on strategic improvements and innovative solutions for new challenges and business requirements.

Where AI is used for support

However, as the boundaries of what is technologically feasible are increasingly being expanded, the role of data center experts is also changing. AI-supported tools in particular are providing significant relief. Among other things, they offer:

  • Diagnosis and troubleshooting in real time: AI systems can continuously analyze network traffic patterns, application performance metrics and infrastructure health indicators. They can detect potential problems within milliseconds, even before they affect the user experience.
  • Predictive analytics: Advanced algorithms process historical data and current trends to predict potential system and capacity bottlenecks or hardware failures. This enables teams to carry out preventive maintenance and capacity planning with a high degree of accuracy.
  • Proactive problem solving: When potential problems are detected, AI systems can automatically initiate remedial actions or provide the team with detailed recommendations on how to fix them. This can include rerouting traffic, adjusting resource allocation or initiating failover procedures.

"AI tools will not replace expertise in data center teams, but they will empower them to perform at an even higher level. The experts will ensure that AI is implemented effectively, interpret their findings and step in when human intuition is required to solve complex challenges," explains Manfred Felsenberg, Senior Director Data Center Global at Juniper Networks.

Laser vibrometry: measuring vibrations from product development to quality assurance

Analyzing vibrations in components, products or systems not only provides valuable insights for research and development, it also offers potential for improvements in quality assurance in production. As a non-contact measurement method, optical laser vibration measurement allows an unadulterated view of the vibrations. Scanning vibrometers even make it possible to analyze the vibration amplitudes of any surface.

Measurement setup with a 3D scanning vibrometer during a modal analysis (Image: Polytec GmbH)

If solid materials are subjected to mechanical stress or electrical excitation, they deform and begin to vibrate to a greater or lesser extent. These vibrations depend on the shape, the material, the excitation and many other factors. Laser vibrometers are used to measure and analyze the vibrations without contact. These are used to evaluate different design variants during development and to optimize products. However, deviations in vibration behavior can also indicate faults in the product during production.

Range of application of laser vibrometry

In vibroacoustic quality testing, a laser Doppler vibrometer scans objects for vibrations precisely and without contact on practically all surfaces (image above). Measurement data such as frequency response and resonance frequency, impulse response and data on damping properties are obtained. The optical measurement with laser light produces a map of the amplitude distribution of the vibrations without influencing the measurement object, e.g. through contact or mass loading (as with accelerometers). The method is suitable for almost any vibration-related problem in research, development, production and condition monitoring or quality assurance and for objects of different sizes: from entire car bodies, large aerospace parts, motors and actuators to micro components such as MEMS or biomedical samples and components in the micrometer range. Depending on the task and sensor design, vibrations up to the GHz range can be detected or, as with the new VibroScan for surface scanning, frequencies up to 32 MHz can be recorded fully digitally.

Optimize desired oscillations

Vibrations are not undesirable everywhere. We all appreciate the vibrating alarm in cell phones or use electric toothbrushes. In many applications, it is important to find the best product design so that vibrations fulfill their purpose optimally. This is where scanning vibrometers are used, which create an areal vibration analysis. Applications in industry include vibrating conveyors or control and operating panels. High-quality packaging systems and industrial joining processes that use ultrasonic welding can also be developed more quickly or checked and optimized during operation with the help of a vibration analysis. Another application is the "vibration transport" of liquid droplets, for example in medical analysis. However, vibration analysis is also a reliable method for developing high-quality products for consumer goods: The vibration of a loudspeaker membrane, which provides the sound of a loudspeaker box, can be analyzed and improved. There are also a large number of less obvious applications such as fans, computer housings, medical products and structure-borne noise and therefore vibrations also play a major role in production systems.

Minimize unwanted vibrations

Deviations in the vibrations of an object from the target specifications allow conclusions to be drawn about the smooth running of drives, manufacturing deviations in production, incipient bearing wear and many other faults. This is where vibrometry can be used inline for quality assurance. The prerequisite is that the sensor can detect and evaluate vibrations quickly and precisely and that the measuring system can be integrated into a production system as easily as possible. Polytec's vibrometers support various interfaces such as COM/DCOM, offer an internal macro language and provide an API for programming. The measurement data is usually transmitted via TCP/IP Ethernet. Polytec also offers extensive tools and examples to ensure smooth integration.

Measuring deviations, but where?

If vibration measurements are used for quality control, the following questions arise: Where can precise measuring points be found for reliable quality assurance in order to identify deviations and minimize rejects? Which conclusions can be drawn from which surface based on deviations? Laser Doppler vibrometers provide good indications here, even during the development of the intended test method: The best measuring points and surfaces can be found as early as the development stage to indicate the specific properties or possible defects through their vibration behavior. This allows measurements to be taken at a meaningful maximum amplitude point, which saves time during commissioning and ensures meaningful quality data on the products.

Improve signal-to-noise ratio

In practice, measuring surfaces are usually optically rough. This means that the light is not only reflected, but also scattered. It contains dark and light areas, so-called speckles. This effect leads to fluctuations in light intensity at the photodetector and, in optical measurements, to broadband noise and unwanted signal dropouts. Therefore, several measurements or a high number of averages are often necessary for a good result. Polytec solves this problem with QTec technology, which uses multiple photodetectors to drastically improve the signal-to-noise ratio. For this purpose, QTec vibrometers use an innovative multi-channel interferometer with receiver diversity. It bundles the best measured values from different perspectives and recombines them for a consistent measurement result. Each detector is an observer of the measuring point with its own perspective and sees its own random speckle pattern (image below). The combination of the signals from the spatially distributed detectors then automatically results in a statistically stable signal level for each individual measurement, regardless of the measuring surface. With this new method, measurements can be taken up to ten times faster, as one measurement is sufficient and no further averaging is required.

New measurement options

To measure both large and very small parts in the shortest possible time, RoboVib® combines a fully automated experimental modal analysis with VibroScan QTec Xtra 3D. The scanning vibrometer is mounted on a robot arm and moved over the object, e.g. a vehicle body. This reduces the testing time, even for complex 3D components, from days or even weeks to just a few hours thanks to comprehensive 360° measurements. For smaller parts, RotoVib automates® experimental whole-body modal analysis since 2024. Here, the test object rotates around its own axis on a turntable. Automatic repositioning allows the test object to be measured automatically from all sides. Thanks to the effortless set-up, users also save valuable measuring time here.

If measurements are to be taken through a layer of water for certain applications, the wavelength of the laser must be adapted to the water medium. Polytec's latest product, VibroScan QTec Neo, offers a HeNe laser in the measuring head whose wavelength is not absorbed by water. This means that sound field analyses of hydrophones (underwater microphones) or components of medical ultrasound applications can now be carried out under water for calibration purposes just as easily as in air. Here too, QTec technology drastically shortens the measurement time by minimizing dropouts.

On-site measurements, for example by a service provider, also require compact measuring devices that are easy to transport and install. The modern VibroScan systems for area measurement are on average around 50% smaller than the 1D predecessor models. This means that the measuring device can also travel as luggage, especially when traveling by air. AI functionality is also incorporated into the vibration measurement thanks to the associated PSV software (Polytec Scanning Vibrometer). This increases user-friendliness and reduces the set-up time for the measurement, for example through automatic object recognition and 3D adjustment. This also significantly reduces the amount of training required by the user.

Quality control, data management and supply chain as the most important AI use cases

The trend study "Digital 2030" by valantic and Handelsblatt Research Institute shows the most important use cases of AI in practice: quality control, data management and supply chain.

Artificial intelligence now supports the processes of DACH companies in a variety of ways. In collaboration with the Handelsblatt Research Institute (HRI), the digital consulting, solutions and software company valantic examined which use cases are particularly important for companies and what role industry affiliation plays in this. The results show that AI applications are already very popular with companies, particularly in quality control and automated data and document management. Supply chain optimization with AI is also an important field of application for many.

valantic and the HRI surveyed around 700 decision-makers from companies in Germany, Austria and Switzerland to find out what added value they are already achieving with the use of AI applications within their business processes (Applied AI). According to the survey, two out of three companies already report measurable benefits based on AI applications - for example in the form of efficiency gains, material and cost reductions or increases in sales and profitability. The study also looked at the question of how relevant these different use cases are.

Which use cases are particularly important?

As part of the survey, the client of the study differentiated between 14 use case clusters and asked the participants which of these application areas were most important for their own company. The following five clusters were given the highest relevance by the respondents:

  1. Quality control: Identify defects and ensure product quality by means of visual or other sensory inspections.
  2. Document and data management: Extract, process and manage information from documents and data records in large quantities, automatically and in high quality.
  3. Optimization of the supply chain: e.g. precise demand forecasting, optimization of delivery routes, reduction of inventory, optimized production and logistics planning.
  4. Robotics & Smart Products: Automation of product functions; interaction of sensor technology, control and logic for autonomous functioning and optimization of hardware products.
  5. Automation in customer service: chatbots and virtual assistants for processing customer inquiries and providing support.

AI-supported creation of media content still less relevant

While the top 5 AI use cases were each named as the most important for their own company by around a third of those surveyed, C-level decision-makers still attach comparatively little importance to the classic use cases of generative AI. For example, the generation of creative content (images, text, sound or video) was only one of the most important areas of application for AI applications in their own company for just under one in five (19%).

Another finding of the study is that the areas of application that are assigned the highest relevance for AI applications vary depending on the sector to which the companies belong. For example, companies from industrial sectors such as automotive, food and beverage production or manufacturing generally attach great importance to quality control using AI, while most decision-makers in the healthcare and pharmaceutical sectors cite document and data management as an important use case. The most frequently cited use case in the retail and consumer goods sector is supply chain optimization. In contrast, purchasing and sales are extremely important for utilities companies, with many respondents naming price optimization as an important application.

Laurenz Kirchner, Managing Director and Data & AI Practice Lead at valantic, says: "Our study shows that AI is no longer a vision of the future, but is actively used in many companies. For many companies, the focus is shifting to the question of which areas of application offer the greatest benefits in their own company. Decision-makers need to prioritize use cases with real added value and strategically anchor AI initiatives. Without clear goals, prioritization and integration into the corporate strategy, there will be no added value."
