3 PAT Workers Sickened by Substance on LRT Cars

3 Port Authority workers...2 light rail operators and a supervisor...were treated last night at UPMC Mercy after they became sick. PAT spokesman Jim Ritchie told the Tribune-Review that city's HazMat team was called to investigate a substance that was found on 2 light rail vehicles on the Allentown line. Ritchie says there was no indication that any passengers became ill. Firefighters say it appears some residue from body work done on the vehicles might have sickened the PAT employees. The vehicles were taken out of service
