Although the number of severe or fatal electrical accidents has decreased in recent years, a comparatively large number of electrical accidents (more than 85% of incidents) still occur in the low-voltage range (<100 volts). The causes include:
- Underestimation of the dangers of electricity at these voltages (230V).
- Disregard for the five safety rules (the application of the five safety rules for establishing and ensuring a voltage-free state for work on electrical systems is rarely applied).
- Behavioral errors.
- Damages and faults in electrical systems and equipment.
- Work in the vicinity of live parts.
- Lack of knowledge.
Even at a voltage of 230V, there is a risk of:
- Dangerous body current.
- Burns caused by the arc fault.
Therefore, comprehensive training for all employees in the field of electrical engineering is essential. It provides a crucial foundation for preventing accidents involving electrical currents. Implementing the accident prevention regulation DGUV Regulation 3 and corresponding VDE regulations aims to prevent hazards during work on live systems and machines, as well as during non-electrotechnical work in the vicinity of electrical systems and equipment.
