2008_08_cranetip.jpgThe Occupational Safety and Health Administration and state Department of Labor were at the World Financial Center yesterday, investigating yesterday's accident where two window washers were killed when a cherry picker toppled. While it is believed the device toppled due to a dip in the ground, another worker told the Post fluid was leaking from it last week and then it was fixed. The men, cousins who were longtime window washers, were working for Total Buildings Service, which told a Daily News reporter who called for comment, "There's really no story here."
