The DGUV publishes the official insurance policies for companies.
All companies must follow these guidelines - if they do not, companies are not insured and individuals are accountable for damages.
If a company is dealing with high-voltage vehicles, the people involved must therefore be adequately trained.
Who needs to be trained and to what level depends on the individual context of the person and is defined in DGUV Information 209-093.
