(Main)Procedure for the assessment of the exposure of workers to electromagnetic fields
Procedure for the assessment of the exposure of workers to electromagnetic fields
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. NOTE 1 This document relates to the exposure limits as specified in the Directive 2013/35/EU. It is intended to protect workers from risks to their health and safety arising or likely to arise from exposure to electromagnetic fields (0 Hz to 300 GHz) during their work. However, this and other Directives can include additional measures for the protection of specific groups of workers and/or specific workplaces for which the employer is required to investigate other protective measures as a part of the overall risk assessment. See Annex A. NOTE 2 Directive 2013/35/EU has been transposed into national legislation in all the EU member countries. It is intended 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 can have additional requirements that are not covered by this standard.
Verfahren für die Beurteilung der Exposition von Arbeitnehmern gegenüber elektromagnetischen Feldern
Procédure pour l'évaluation de l'exposition des travailleurs aux champs électromagnétiques
L’objet de la présente Norme européenne est de fournir une procédure générale d’évaluation de l’exposition des travailleurs aux champs électriques, magnétiques et électromagnétiques sur un lieu de travail pour établir la conformité aux valeurs limites d’exposition et/ou aux valeurs déclenchant l’action de la directive européenne 2013/35/UE. L’objet de cette Norme européenne est de — spécifier comment réaliser une évaluation initiale des niveaux de l'exposition des travailleurs aux champs électromagnétiques (EMF - electromagnetic field), en incluant si nécessaire une évaluation de l'exposition spécifique de tels niveaux par des mesurages et/ou des calculs, — déterminer s’il est nécessaire de mener une évaluation détaillée du risque pour l’exposition aux EMF. La présente Norme européenne peut être utilisée par les employeurs pour l’évaluation du risque et, si exigé, pour les mesurages et/ou calculs de l’exposition des travailleurs. En se fondant sur les normes spécifiques au lieu de travail et d’autres normes, il est possible de déterminer si des mesures/actions préventives doivent être prises pour se conformer aux dispositions de la directive. Les fréquences couvertes sont comprises entre 0 Hz et 300 GHz. NOTE 1 La présente Norme européenne a été élaborée dans le cadre du Mandat M/351 et se rapporte aux limites d'exposition spécifiées dans la directive 2013/35/UE. Elle est destinée à la protection des travailleurs contre les risques pour la santé et la sécurité pouvant résulter de l'exposition aux champs électromagnétiques (0 Hz à 300 GHz) pendant leur activité professionnelle. Cependant, cette directive ainsi que d’autres peuvent contenir d’autres mesures de protection pour des catégories spécifiques de travailleurs et/ou pour des lieux de travail spécifiques pour lesquels il est exigé de l’employeur qu’il recherche d’autres mesures de protection au titre de l’évaluation complète du risque. Voir l’Annexe A. NOTE 2 La directive 2013/35/UE a été transposée dans les législations nationales de tous les pays membres de l'Union européenne. Il est prévu que les utilisateurs de la présente norme consultent leur législation nationale résultant de cette transposition afin d’identifier les règlementations et exigences nationales. Les règlementations et exigences nationales peuvent inclure des exigences complémentaires qui ne sont pas couvertes par la présente norme.

1 Scope
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.
NOTE 1 This document relates to the exposure limits as specified in the Directive 2013/35/EU. It is intended to protect
workers from risks to their health and safety arising or likely to arise from exposure to electromagnetic fields (0 Hz to
300 GHz) during their work. However, this and other Directives can include additional measures for the protection of
specific groups of workers and/or specific workplaces for which the employer is required to investigate other protective
measures as a part of the overall risk assessment. See Annex A.
NOTE 2 Directive 2013/35/EU has been transposed into national legislation in all the EU member countries. It is
intended 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 can have
