ST. LOUIS (KMOV.com) -- A water main break that threatened the electrical system at Barnes-Jewish Hospital continues to cause trouble.
Water seeped into the hospital’s sub basement, forcing officials to shut off the regular electrical units and turn on emergency generators.
BJC backup power generators can sustain the building's power for six hours, but at 3:30 p.m. the triple digit heat caused the generators to fail.
The regular power system was temporarily restored at 4:50 p.m., but power failed again around 6:15 p.m. Because of the extreme heat, more than 100 patients in Queeny Tower were moved to other areas of the facility.
Most of the patients affected were heart and G-I patients. None of them were under critical care. Without electricity to power an elevator, firefighters had to carry them down the stairs.
"Some that we've moved are in pre and post-op areas of the hospital and in moving them there," said spokesperson Jason Merrill. "If for whatever reason by tomorrow the patients aren't able to get back, there is a possiblity we'll have to call patients to see if they can cancel some elective surgeries, reschedule them for another day."
The 12-inch water main break occurred on Children's Place Drive. The St. Louis Street Department reports no damage to the pavement.
St. Louis City Water Department crews are on the scene working to stop the flow of gallons of water released onto the street and will begin repairs following containment.
