"The fire will happen. It will resemble a gasoline fire. It will be explosive and intense in nature," spokeswoman Janet Smith told The Associated Press late Wednesday.

"As the temperature rises, the natural state of these materials will decompose. A white smoke will result, and that will catch fire," Smith said. "So the fire is imminent. The question is when."
At least 2 explosions already reported. 1 police officer injured, possibly more. This is at the Arkema plant in Crosby.
