February 28, 2010 by Alison Gendar New York Daily News A lawyer in two Ground Zero sickness cases green-lighted for trial says he has a smoking gun: buried city documents that prove firefighters should have gotten respirators. The papers emerged in a veritable mountain of files the city turned over to workers who believe they were sickened by toxins after the 9/11 terrorist attacks. Lawyer Andrew Carboy, whose firm represents more than 600 firefighters, said the FDNY had rules on the book requiring Bravest be equipped with respirators before Sept. 11. But memos showing that weren't handed over until this summer - in a data dump of 3 million documents - five years after the legal battle began. "They provide everyone with helmets, with bunker gear, with [air] packs. They could have done the same with respirators, and they withheld the documents saying they had a program to do it," Carboy said.
