Why do electricity and gas diagnostics?

According to the White Paper published by Diagameter and the National Observatory of Electrical Safety (ONSE), each year in France more than 3,000 people are electrified, 5,000 people are poisoned by carbon monoxide (CO) and there are more than 50,000 fires.
In 80% of faulty installations, the problem would be related to a need to ground.
In order to avoid new accidents, the public authorities have decided to extend the gas and electricity diagnostics to rented properties. Indeed, these two documents are mandatory since 2009 when selling a property of more than fifteen years.
