Nashville (WVLT/AP) - Several people have been transported to area hospitals, including two people that were critically injured, following an electrical explosion this morning in Nashville.
The explosion happened in the basement of the historic Metropolitan Davidson County Courthouse in Nashville as crews were working to install a new transformer underground.
Fire department spokesman Charles Shannon said there were five workers near the transformer at the time.
According to WTVF, the CBS affiliate in Nashville, two Nashville Electric Service workers were taken to the Vanderbilt University Medical Center Burn Center in critical condition.
The Nashville Fire Department said a third was treated for non-critical injuries at Baptist Hospital. A fourth NES employee refused treatment.
NES spokesman Tim Hill said a fifth worker, a representative of the transformer manufacturer, also was injured. The extent of those injuries were unknown.
Mayor Bill Purcell's spokeswoman Molly Sudderth says the building was not damaged in the explosion, but the building was evacuated as a precaution.
She said the transformer was located underground outside of the courthouse.
The courthouse on James Robertson Parkway is currently being renovated. It houses the mayor's offices and some courts.
