Acido solforico è fuoriuscito a due riprese, giovedì, da una conduttura all’interno di uno degli edifici della CABB AG, nella zona industriale di Schweizerhalle, a Pratteln.
Nel primo caso il liquido, poche decine di litri, è entrato in contatto con l’acqua usata dai pompieri per circoscrivere la fuga e ha reagito provocando una nuvola di vapore comunque subito dissoltasi. Il secondo s'è verificato alcune ore più tardi, mentre era in corso la riparazione della tubatura, e per due persone s'è reso necessario un controllo medico.
L’azienda in questione è ripetutamente salita alla ribalta negli ultimi anni per incidenti vari. In marzo per uno di questi episodi era anche stata aperta un’indagine penale.
