It'll be at least Tuesday before patients are allowed back into Regional Medical Center Bayonet Point, according to Pasco County Fire Rescue officials.
Hospital officials had previously indicated they hoped to open the doors to patients as early as Monday.
The Hudson hospital was forced to evacuate all 209 of its patients Wednesday night after a lightning strike caused an electrical fire that damaged wiring and killed the power, county and hospital officials said last week. The strike and fire also took out the hospital's backup power.
While hospital and Withlacoochee River Electric Cooperative workers were able to restore the hospital's main power by Thursday morning, its backup power was still down. State regulations prohibit the hospital from readmitting patients until it has backup power.
Inspectors from the Agency for Health Care Administration were scheduled to examine the facility Tuesday, fire rescue officials said. The hospital must pass inspection before it can begin treating patients, though it was unclear how long the inspection process would take.
