Still burning, they have the foam truck from Lubrizol ( another local chemical co.) trying to control some of the flames while watching cracks in the wall grow and preparing for its fall. They do have a fairly good control of the heat from reaching nearby ry rail cars.
@5:34 they are calling out a rapid change in the smoke on several sides of the building.
Still have heavy fire coming out of the 'alpha' side of the building no fire visible on 'bravo' and 'charlie' sides. Crew and equipment change out has been in process since around 7:00 and is still in progress
