Simulation of a chemical accident successfully conducted at the TEPSA facilities in the Port of Barcelona


More than 200 people from the emergency services and TEPSA, as well as hundreds of people from nearby facilities, participated in the exercise, which was carried out on 21 April.
Companies and other activities close to the scene of the accident took part in the containment exercise once its external impact became known.

The Catalan Government’s Civil Protection Unit (DGPC), which is part of the Home Affairs Department, in conjunction with TEPSA and the Port of Barcelona, organised a simulation of a chemical leak at the TEPSA facilities at the Port of Barcelona’s Energy Dock, activating the emergency phase of the Catalan Government’s External Emergencies Plan of the Chemical Sector (PLASEQCAT).


The exercise simulated a failure in the security systems, which caused the over-filling of an acrylonitrile tank during the transfer process between tanks. The spilt product, approximately five tonnes, was collected in the tank’s bund wall, producing a toxic cloud when it evaporated. Acrylonitrile (UN 1093) is a toxic, highly flammable substance, which is why the distances affected by the toxic cloud, in peak atmospheric stability conditions, covered a radius of 652m in the Intervention Zone and 1,200m in the Alert Zone.

Members of the Barcelona Firefighters, Medical Emergency System (SEM), Catalan Police Force (Mossos d’Esquadra), Barcelona Urban Guard (GUB), Civil Guard, Port Police and TEPSA’s intervention and first aid teams participate in the drill.
The Director General of Civil Protection Unit, Joan Delort, the Assistant Director of Civil Protection Planning, Núria Gasulla, as well as other lead officials deom the Civil Protection Unit and representatives of other organisations also attended the simulation as observers.
