This part of IEC 60479, which is a technical report, summarizes the basic parameters for lightning and their variability insofar as they apply to human beings and livestock.

The possible direct and indirect interactions of strikes with bodies of living beings are indicated and the resulting effects caused by lightning currents for the organism are described.

The object of this report is to show the differences of effects on human beings and livestock due to lightning strokes versus those effects of electric shocks derived from electrical systems.
