Update 2:15 pm

Ok...one prayer has been answered! Thank You God! My dad has been transported by ambulance to the hospital. He and mom are out of the danger zone. Now they can start trying to figure out what's up with his back.
I called my brother to check and find out what was going on. He was sitting on a little road behind my parents' house watching the fire. While I was talking to him he saw a few large fire balls, something else in the plant was exploding. The new foam has not yet arrived.
Thanks for your continued prayers.
