The incident happened at about 8:15 p.m., according to Capt. Ben Gonzales of the Santa Ana Fire Department.
“At this time we are returning some of the patients to the emergency room,” Gonzales said. “We still are systematically going floor by floor looking with our HazMat team to see if we can determine the exact cause of the odor itself.”
Gonzales said rescuers and hospital staff were able to get the building fully evacuated in about 20 minutes, getting the 75 to 100 people inside to safety.READ MORE: DUI Suspect Arrested In Deadly Traffic Collision That Killed 2 People On 110 Freeway In South LA Sunday
