Three technicians at the Smoky Mountain Opry were transported to the hospital after passing out last night from exposure to carbon dioxide gas. Officials say the three were in a special technician room that was separate from where the audience sits for performances. As of this morning, one person is being treated at UT Medical Center while the other two have been released from the hospital. The building was evacuated at the time of the incident and there were not any other injuries reported. Officials say shows will continue at the Smoky Mountain Opry.
