I am working an assignment in Little Rock, Arkansas at present. A chemical plant in nearby Conway blew up just before lunch today. I heard about evacuations on the radio, and had to check my map to see how close I was. Luckily, not too close, and the prevailing winds were blowing favorably. I had just been checking my BOB last night, and had replaced some out of date medications.
Just goes to show, it never hurts to go through your gear from time to time, and I need to look a little more closely at what industrial sites are nearby.
