Surprising phone call

Today,in the middle afternoon my sister surprised me with her phone call. She told me that they were just told to a leave the building do to a huge gas line brake. Everybody had to go, grab a coat and meet on a parking lot. Immediately 5 firetrucks and police cars showed up blocking exits and entries to the building and securing employees waiting on a parking lot. Everyone was surprised and so in this same worried how long will take the fireman to secure the area so people can leave. Couple hours later I've received another phone call was on her way home. All the gas lines were shut off and secure. I'm wondering if she will work tomorrow. I'll be surprised if they would.
