Chemical plant near Seville in Spain experiences large blast, causing toxic fumes alarm
A catastrophic explosion at a chemical products warehouse in Alcalá de Guadaíra, Seville, Spain, occurred on Wednesday, May 14, 2025, around 1:20 p.m. local time. The industrial solvents and flammable compounds storage facility, operated by Plainsur, was quickly enveloped in flames, leading to the release of a thick black plume of smoke that was visible for miles.
The explosion's cause is currently under investigation, with preliminary assessments suggesting a possible chemical reaction or equipment failure as potential culprits. Authorities have ruled out cyber attacks and intentional sabotage as possibilities.
In the aftermath of the blast, emergency evacuations were ordered for the warehouse's staff and surrounding businesses. Public alerts were issued to approximately 80,000 residents in the area, advising them to stay indoors, close windows, and doors, and wear face masks due to the fear of toxic fumes. Initial conflicting reports mentioned a minimum of two injuries: a warehouse worker suffering from burns and a firefighter fighting the blaze with smoke inhalation. Both individuals are reported to be stable following medical attention.
Seven fire stations across the region collaborated to contain the blaze, which took hours to extinguish and was finally under control by the following day. Concerns regarding the fire's environmental and public health impact were alleviated after the air quality returned to a safe level by May 15, allowing residents to resume normal activities.
The incident has sparked concerns about the industrial safety standards and emergency preparedness in Spain, particularly for facilities handling hazardous materials. The effectiveness of Spain's Es-Alert system in rapidly notifying and instructing the public was demonstrated during this incident.
The explosion in Alcalá de Guadaíra also follows a recent pattern of industrial and transport-related incidents in Spain, including a chemical factory fire in the northeast that led to widespread health warnings and lockdowns.
In summary, the explosion highlights the importance of stringent safety protocols and robust emergency response infrastructure in industrial zones, especially those managing hazardous substances.
