Electromagnetic fields "electro smog"
Electromagnetic fields are generated by the operation of electrical power engineering
installations such as transformers, converters or motors.
Electromagnetic fields can interfere with electronic devices, which could cause them to
malfunction. For example, the operation of heart pacemakers can be impaired, potentially
leading to damage to a person's health or even death. It is therefore forbidden for persons
with heart pacemakers to enter these areas.
The plant operator is responsible for taking appropriate measures (labels and hazard
warnings) to adequately protect operating personnel and others against any possible risk.
• Observe the relevant nationally applicable health and safety regulations. In Germany,
• Display adequate warning notices (pacemaker symbol).
• Place barriers around hazardous areas.
• Take measures, e.g. using shields, to reduce electromagnetic fields at their source.
• Make sure that personnel are wearing the appropriate protective gear.
