The scope of this European Standard is to provide a general procedure in order to assess workers' exposure to electric, magnetic and electromagnetic fields in a work place to demonstrate compliance with exposure limit values and action values as stated in the Council and European Parliament Directive 2004/40/EC. The purpose of this European Standard 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 European Standard 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 standards it can be determined whether preventive measures/actions must be taken to comply with the provisions of the Directive. The frequencies covered are from 0 Hz to 300 GHz. NOTE 1 This European Standard is written under Mandate M/351 and relates to the exposure limits as specified in the Directive 2004/40/EC. It is intended to protect workers from risks to their health and safety arising or likely to arise from exposure electromagnetic fields (0 Hz to 300 GHz) during their work. However, this and other directives may include additional measures the protection of specific groups of workers and/or specific work places for which the employer is required to investigate other protective measures as a part of the overall risk assessment. See Annex A. NOTE 2 The Council and European Parliament Directive 2004/40/EC will be transposed into national legislation in all the EU member countries. It is recommended that users of this standard consult the national legislation related to this transposition in order to identify the national regulations and requirements. These national regulations and requirements may have additional requirements that are not covered by this standard.
