|The scope of this document is to provide a general procedure for the assessment of workers’ exposure to electric, magnetic and electromagnetic fields in a workplace in order to determine compliance with exposure limit values and/or action levels as stated in European Directive 2013/35/EU. The purpose of this document is to:— specify how to perform an initial assessment of the levels of workers’ exposure to electromagnetic fields (EMF), if necessary, including specific exposure assessment of such levels by measurements and/or calculations;— determine whether it is necessary to carry out a detailed risk assessment of EMF exposure. This document can be used by employers for the risk assessment and, where required, measurement and/or calculation of the exposure of workers. Based on specific workplace and other standards, it can be determined whether preventive measures/actions have to be taken to comply with the provisions of the Directive. The frequencies covered are from 0 Hz to 300 GHz.
