Associated Press via Denver Post:
A Houston-area chemical plant that lost power after Harvey engulfed the area in extensive floods was rocked by two explosions early Thursday, the plant’s operator said.
Arkema Inc. said in a statement on its website that the Harris County Emergency Operations Center reported two explosions and black smoke coming from the plant at about 2 a.m.
Authorities had many hours warning that this fire and explosion were definitely going to happen.
“As the temperature rises, the natural state of these materials will decompose. A white smoke will result, and that will catch fire,” [plant spokeswoman Janet] Smith said. “So the fire is imminent. The question is when.”
