Using sensors to create a healthy working environment

We have translated these opportunities into a vision for the future: the Virtual Occupational Hygiene Assistant (VOHA). Together with partners, we are working on all the elements needed to put this vision into practice and in this way help reduce the disease burden resulting from exposure to hazardous substances.

New way of measuring

Air pumps have been used to measure exposure since as far back as the 1960s (Personal Air Sampling, PAS). This made it possible to better identify and manage causes of occupational diseases. Recently, however, the Dutch Social and Economic Council (SER) published a report stating that a reduction in workplace risks has not been seen for some years now. We can change this by making smart use of sensors.

The conventional measurement method mainly provides accurate information on the average exposure over the measurement period; with sensors you gain a greater understanding of the variation in exposure over this period, making it easier to identify where, when, and why exposure occurs. This information gives you the insights needed to actually reduce exposures and in this way prevent occupational diseases more effectively. Although sensors are not usually as accurate as PAS measurements, we are exploring the new opportunities they open up to help companies during the regulatory process, for example by calibrating sensors and making use of the vast amounts of exposure data they generate (quantity versus quality).

Successful implementation in the workplace

Good coordination between all the different stakeholders is essential if sensors are to be used successfully to create a healthier working environment. Workers are exposed to risks, employers are responsible for ensuring safe workplaces, occupational hygienists perform measurements and offer advice, the government makes policy, and the Netherlands Labour Authority monitors the situation on the ground. We work together with all stakeholders to determine what is needed to fully reap the benefits of measuring using sensors. For example, we collaborate with occupational hygienists from IDEWE, GCG, and the Dutch Association of Occupational Experts (NVvA) to develop guidelines and tools.

Guidelines on the use of sensors

To ensure that, in the end, the VOHA approach does actually reduce exposure and therefore also the disease burden, we are developing guidelines on the use of sensors with international partners. Together with HSE and NIOSH, we are focusing on facilitating the use of sensors in the workplace. We also answer practical questions, such as how do you determine which is the most suitable sensor to measure a specific exposure or situation, how do we determine the validity of the data obtained, and what fresh information can we extract from all this new data? This information is being incorporated into guidelines.

Privacy and ethics in sensor data use

Sensors collect data, which is often about people. The introduction of sensors into the workplace will therefore have an impact on ethical values regarding, for example, health and well-being, the right to self-determination, privacy, trust, fairness, and responsibility.
