4 Plunge to Deaths in Polish Industrial Chimney Firefighters in central Poland say four maintenance workers have plunged to their deaths some 120 meters (400 feet) down a chimney that they were working on at a coal-fired power plant. Spokesman Waldemar Krakowiak said Wednesday that the four were standing on a platform that came loose inside a chimney at the Kozienice plant, some 80 kilometers (50 miles) south of Warsaw. They had been carrying out maintenance on the chimney. Prosecutors are investigating.
