SEATTLE -- Families of six workers killed in an explosion at Tesoro's Anacortes, Wash., oil refinery last year filed a wrongful-death lawsuit Wednesday, charging the refinery owner deliberately ignored dangerous conditions that led to the blast.
The explosion -- which state investigators concluded was preventable -- killed seven workers. Six of their families joined the lawsuit filed in Skagit County Superior Court. Also suing is a contractor who was burned but survived.
The lawsuit accuses Tesoro of failing to inspect decaying equipment and ignoring industry safety standards and federal laws. It said the refinery routinely pushed equipment above safe pressure limits because it was "economically attractive" and boosted production.
