PITTSBURGH (AP) — Federal documents show that crews doused minor fires on the Liberty Bridge twice in the three days before a construction fire closed the Pittsburgh bridge for 24 days in September. The documents obtained by the Post-Gazette (http://bit.ly/2lz3VEo ) from the federal Occupational Safety and Health Administration show that a safety official for contractor Joseph B Fay Co. had removed an employee assigned to watch for fire in the area where the blaze occurred. PennDOT and OSHA have both said hot residue from a blowtorch ignited plastic piping and a construction tarp on Sept. 2. PennDOT officials say Fay didn't report the Aug. 30 and Sept. 1 fires to the agency because they were quickly handled by employees at the site. A Fay official told OSHA he wasn't aware of the fires. ___ Information from: Pittsburgh Post-Gazette, http://www.post-gazette.com
