A gas explosion during metro construction in Sants injured eight people, prompting city officials to call for accountability from responsible agencies. The incident raises safety concerns among residents.

A significant gas explosion occurred in the Sants-Montjuïc area of Barcelona on Wednesday, injuring eight individuals, two of whom are in serious condition. The incident took place during ongoing construction work aimed at improving accessibility at the local metro station. City officials are now demanding accountability from the responsible agencies involved in the project.

The explosion was triggered when a drilling machine accidentally punctured a gas pipeline around 3 PM. Despite immediate notifications to the gas company, it took approximately seven hours for the situation to escalate into a dangerous deflagration that sent flames soaring over ten meters high. Local resident Maribel expressed her fear, stating, “We were told not to go out onto our balconies; it was unsettling knowing such danger was so close.” Another nearby resident described seeing firefighters calmly managing the situation despite the towering flames.

The construction project is overseen by the Departament de Territori and began earlier this year with an estimated budget of €16 million. Albert Batlle, Barcelona’s Deputy Mayor for Security, addressed reporters following the incident and emphasized that all parties involved must be held accountable for their roles in this alarming event.

In response to public concern, Carles Vaccaro from Infraestructures.cat reassured citizens that while there have been recent incidents linked to Territori’s projects—such as another issue on Line 9—the occurrences are coincidental and unrelated in nature. He urged residents to trust that safety protocols would be followed moving forward.

The fire department employed specialized techniques to manage the gas leak effectively. Firefighters utilized inflatable plugs to seal off escape routes while maintaining a constant water spray on the flames. This method allowed them to control the situation without extinguishing it entirely until they could secure all potential leaks.

This incident is reminiscent of past construction-related accidents in urban areas where infrastructure improvements led to unintended hazards. For instance, similar events have historically raised questions about oversight and safety measures within public works projects across major cities worldwide.

As investigations continue into what caused this latest mishap, residents remain on edge about future construction activities in their neighborhoods. Many are calling for stricter regulations and better communication from authorities regarding safety measures during such projects.

For those living near Sants-Montjuïc or planning to visit, it’s advisable to stay updated through local news outlets regarding any ongoing safety measures or road closures resulting from this incident. Authorities will likely provide further information as they assess both immediate responses and long-term implications for public safety.
