Just A Reminder: How Fast Can You Evacuate?

5,000 people in Knoxville, Tennessee, have been forced to evacuate after a train hauling a toxic chemical derailed and caught fire. The cargo was acrylonitrile, which causes dizziness and nausea and is highly flammable. The evacuation may be for 24 to 48 hours. Shelters have been set up at a couple nearby schools. Just a reminder that you may only have seconds or a few minutes to grab your stuff (hopefully a BOB or 72-hour kit) and go.
