In the study an industrial occupational setting was investigated in order to determine the workers exposure to the magnetic fields from induction ovens and to develop risk mitigation procedures to lower the exposure. Electromagnetic field measurements were conducted and the workers exposure to the electromagnetic fields was assessed in the framework of the new occupational electromagnetic field legislation. The results show that the exposure could be significantly reduced by implementing relatively easy mitigation measures, including workplace rearrangement, work procedure redesign etc. Time-weighted average exposure to the magnetic field could be lowered from 2.57µT (maximum observed procedure case) to 0.12 µT (recommended procedure scenario after interventions). The investigation also revealed that little attention is paid to training the workers who may be affected by high levels of electromagnetic fields. Considering the requirements of the new European Union and national electromagnetic field legislation, immediate planning of appropriate schooling programs is necessary for all parties involved: employers, workers, work environment specialists.
