9.6 Protecting persons from electromagnetic fields
Overview
Protection of workers from electromagnetic fields is specified in the European
EMF Directive 2013/35/EU. This directive is implemented in national law in the
European Economic Area (EEA). Employers are obligated to design workplaces
in such a way that workers are protected from impermissibly strong
electromagnetic fields.
To this end, assessments and/or measurements must be performed for
workplaces.
Precondition
1. The laws for protection from electromagnetic fields in force in individual EU
member states can go beyond the minimum requirements of the EMF
Directive 2013/35/EU and always take precedence.
2. The ICNIRP 2010 limits for the workplace are the basis for the assessment.
3. The 26th BImSchV (German Federal Emission Protection Regulation) defines
100 μT (RMS) for the assessment of active implants.
According to Directive 2013/35/EU, 500 µT (RMS) at 50 Hz is applicable
here.
4. Compliance with the limit values was assessed for the following
frequencies:
– Line frequency 47 ... 63 Hz
