Abschnitt 5.2 - 2. Non-electrical work
In addition to the intended use of the vehicle, non-electrical work must also be performed on it (e. g. panel work, oil and wheel changes, brake component replacement in the proximity of wheel hub motors, work on dampers in the proximity of the HV lines) and electrical work on the conventional vehicle electrical system (up to 30 V AC and 60 V DC). Employees may be exposed to an electrical hazard during this work owing to human error or faults. They must be made familiar with these hazards, the protective measures and the codes for behaviour. The topics and duration of instruction must be geared to the nature of the work to be conducted and to the anticipated hazard potential associated with it.
More comprehensive mechanical work which may be performed in the proximity of HV components, such as welding, drilling or grinding work, requires knowledge of the precise location of the HV components. Employees' awareness must be raised of the hazards which may arise during the use of tools and other equipment in the proximity of the HV system. They must be familiar with the markings of the components. The instruction must include making them aware that work on the HV components is not permissible. Inadvertent kinking or crushing of HV lines or damage to them must be reported to the responsible expert. Failure to observe these requirements may lead to dangerous electric shock or arcing.
The instruction must be documented.
The topics of this instruction must include:
Operation of vehicles and the associated equipment,
Performance of general tasks which do not require isolation of the HV system,
Location and marking of the HV components and lines in and on the vehicle,
Performance of all mechanical tasks on the vehicle (but: don't touch orange!),
Isolation of the HV system as specified by the manufacturer, serving as an additional safety measure to prevent unauthorized or inadvertent use,
Appointment of the individual to be consulted in the event of uncertainty (such as the expert in HV systems),
Impermissible work on the vehicle,
Organizational procedure for electrical work that is performed under the control and supervision of a skilled electrical person for HV systems.
Instruction must last for between 0,5 and 2 teaching periods, according to the nature and scale of the work.
