Safety information
1.4 Residual risks
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 pacemakers can be impaired, potentially leading
to damage to a person's health or even death. It is therefore forbidden for persons with
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 hazard warning notices.
• 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.

WARNING
"electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by
the German statutory industrial accident insurance institution.
