Fire broke out Thursday morning at the Park Plaza Apartments, in the 1900 block of Southwest Park Avenue.
Portland Fire & Rescue said the cause of the fire on the top floor of the 11-story building was "improperly discarded smoking materials." One person was taken to the hospital with burns to his hands and arms.
Toma Matisoff, the roommate of the injured man, told KGW that he was laying in his room mid-morning when when he heard a smoke detector. He initially ignored the alarm until his roommate banged on the door and asked for help.
Matisoff then realized that smoke in the apartment was thick. He called 911. His roommate, meanwhile, tried to put out the fire in his own room to no avail.
