Every manager of an industrial site knows that a thunderstorm in France can transform an ordinary day into a major safety challenge for people and equipment. Managing the meteorological impact of lightning is not limited to avoiding electrical failures; it’s about protecting production, the environment, and the company’s liability. The October 4, 2010 decree requires a lightning risk analysis compliant with NF EN 62305-2 standard, followed by installation and regular verification of protection systems. Understanding how to structure these processes makes it possible to limit interruptions and economic losses.
