it takes 200 firefighters two full days to bring the massive fire under control. fortunately, none of the 50 employees of the chemical facility or any firefighters are injured. 209, you might want to back your unit up. a train carrying propylene, a highly flammable petrochemical used in manufacturing, blows up in texarcana, arkansas, early in the morning october 15, 2005. a police car s dashboard camera captures the massive explosion. with no time to turn around, the officer throws his car into reverse and races backwards to escape the growing river of fire coming right at him. it was quite massive. just as far as you could see, just nothing but flames.
