The dangers of a thunderstorm should not be underestimated. On average, the Netherlands will experience a thunderstorm about 25 days per year. It is key to make employees aware of the dangers of lightning. It is important to be alert to thunder, whether you are working inside or outside. The place and time of lightning striking can never be determined precisely.
If you are unable to reach a safe place in time, proceed as follows:
Thunderstorms move fast; their speed can be estimated following the rule of thumb
1 kilometre when there is 3 seconds between the lightning flash and the sound of thunder!
In case of an approaching thunderstorm, cease work immediately and find a safe place to hide!!!
