A story we've been following all day involves an ammonia leak which happened at the Swift Meatpacking Plant in Worthington, Minnesota.
A leak which sent 49 people to the hospital.

We now know all 49 are back home in good condition. The company credits a quick response and evacuation plan after discovering a ruptured pipe .
We also found, the local hospital had it's own role to play.

Fire rescue vehicles and Sanford ambulances were picking up patients at the Swift plant and bringing them here throughout the morning to Sanford regional hospital in Worthington. The halls were full of people earlier in the day, but the hospital's CEO says they handled this case with ease because of the fact that they had an emergency plan called a "code orange".

Swift employee Elizabeth Olivares was evacuated. She doesn't speak English, but her friend Emma describes how a scary situation turned into a scene of action. "She said the ambulance took them to the hospital right away."

"These are all the emergency treatment rooms." Hospital CEO Lynn Olson says they got the call about 10:20 this morning. "We started out not knowing how many patients would come in and eventually when that number got to be over 30, we needed some extra help."

The extra help came from off duty staff and doctors from outside clinics...it's part of their 'Code Orange Disaster Plan'. "These things are stressful but it was also a pretty proud day for us to see our staff really kick it into gear and take care of our patients."

Elizabeth wasn't a patient herself... but is glad her friends benefited from that care. "She said she hopes everybody right now, they're okay, and she said she thinks it's okay. (The hospital staff) acted really fast to get the people to feel better in the hospital."
