The morning calm in Vilanova i la Geltrú shattered at 2:20 AM on May 10, 2025, when a fire erupted at Clim Waterpool’s storage facility. Inside the warehouse sat 70 tonnes of chlorine – enough to treat thousands of swimming pools across the region.

“The situation required immediate activation of our PLASEQCAT protocols,” stated Catalonia’s Civil Protection Service. Within minutes, more than 60 specialized firefighters, medical teams, and local police rushed to contain what quickly became a toxic cloud drifting toward populated areas.

Authorities acted swiftly to protect 160,000 residents across five coastal towns. For seven crucial hours, families in Vilanova i la Geltrú, Cubelles, Cunit, Calafell, and Roquetes stayed behind closed doors and windows. Air conditioners fell silent as officials warned against drawing outside air into homes.

The incident raises hard questions about storing large quantities of industrial chemicals near coastal communities. Environmental agencies are exploring alternatives like on-site electro-chlorination systems that could reduce the need for bulk storage.
