A toxic chemical reaction involving organic solvents prompted the complete evacuation of approximately 200 people from the Institute of Microelectronics on the Autonomous University of Barcelona (UAB) campus on Thursday afternoon. Emergency services, including a specialist chemical unit, quickly responded, and officials confirmed no injuries were reported.

The incident occurred around 13:40 at the Institute of Microelectronics of Barcelona (IMB-CNM, CSIC), a leading research centre on the university’s Bellaterra campus in Cerdanyola del Vallès. An unintended reaction involving different organic solvents, carbon-based substances commonly used in labs to dissolve materials, triggered the alert.
Emergency Services Launch Major Response
The fire service of the Generalitat de Catalunya, known as the Bombers, confirmed the incident on social media platform X. They immediately dispatched seven fire crews to manage the situation, underscoring the potential danger.
Significantly, the deployment included the Bombers’ specialist Technological Risk Unit (Unitat de Riscos Tecnològics). This highly trained team is equipped to handle incidents involving hazardous materials, including chemical, biological, and radiological threats. Their presence indicates that the authorities treated the event as a serious chemical hazard requiring expert assessment and containment.
The unit’s primary task upon arrival was to secure the area, assess the toxicity of the fumes, and begin procedures to ventilate the building and neutralise the chemical threat safely.
A Swift and Safe Evacuation
Authorities ordered a full precautionary evacuation of the building, affecting around 200 researchers, technicians, and administrative staff. The team carried out the evacuation swiftly and without incident, ensuring everyone was safely accounted for outside. This prompt, orderly response prevented any harm to the institute’s personnel.
This successful operation highlights the importance of established emergency protocols in high-tech research environments that regularly handle potentially hazardous materials. The incident serves as a reminder of scientific research’s inherent risks and the essential emergency planning needed to mitigate them. Recent events in the Barcelona metropolitan area, such as a devastating fire in L’hospitalet that forced fifty residents from their homes, have brought the effectiveness of emergency responses into sharp focus.
The Autonomous University of Barcelona is one of Spain’s foremost public universities, and its Bellaterra campus is a sprawling hub of education and cutting-edge research. The IMB-CNM, part of the Spanish National Research Council (CSIC), is a critical part of this ecosystem, specialising in the development of micro and nanotechnologies.
An investigation will now determine the precise cause of the toxic reaction. Such inquiries typically review laboratory procedures and safety protocols to prevent similar incidents in the future.
