Ton Koridon explains that he was concerned about the high quantity of fine particulate in the plant. ‘After all, we carry out work that releases particulate. The forklifts that drive through the plant and their tyres, which wear, create pollution as well. We had taken all necessary measures, including source extraction and wearing mouth and face masks. We also have separate extraction on the laser cutting machinery. We are of course fully aware of the dangers of fine particulate to health, which is why decided to have some air measurements carried out, to give us insight into the concentration of fine particulate in the plant.’
