FAQ (Frequently Asked Questions)
Here we answer the most frequently asked questions about our services, inspection obligations and processes.
All companies, public institutions and independent operators of electrical systems and equipment are obliged to have their equipment inspected regularly – in accordance with DGUV Regulation 3.
The inspection intervals depend on the type of device and the location of use.

Office equipment: every 2 years
Tools in workshops: every 12 months
Equipment on construction sites: every 3 months
Nursing beds & medical equipment: mostly annually
We will advise you individually on your inspection intervals.
