The Pays de Gex firefighters intervened at the town of Gex on Thursday, June 2. Workers were vomiting at the intersection of rue Ernest Zegut et rue des Terreaux in a building that was being renovated. They called for help. Two workers used a generator to get electricity.
The carbon monoxide fumes then made them sick. The two workers, aged 23 and 46, were transported to the Saint-Julien-en-Genevois hospital center. Their prognosis for the future is good. Three women were also taken care of by firefighters who worked in the nearby hairdressing salon.
