SAŽETAK: U radu je na primjeru realnog slučaja požara u velikom trgovačkom centru opisan rad vještaka i ekipe za očevid prilikom utvrđivanja uzroka požara. Prikazan je postupak i metode utvrđivanja mjesta nastanka i uzroka požara, te je ukazano na uočene nedostatke i mogući kvar koji je mogao dovesti do požara. Objekt je bio opremljen sustavom za otkrivanje i dojavu požara, ali se njegova aktivacija nije pokazala učinkovitom. Požar se dogodio nakon radnog vremena centra tijekom noći, pa nije bilo potrebe za evakuacijom kupaca i zaposlenih. Požar je izazvao veliku materijalnu štetu zbog gotovo potpunog uništenja objekta, inventara i robe. Pregledom mjesta događaja požara i na temelju pregleda i analize rada zaštitnih sustava te svih dobivenih informacija zaključeno je da je uzrok požara kvar na rasvjetnom tijelu koje se nalazilo u metalnom regalu s policama od iverice na kojima se nalazila tekstilna roba.
