Officials said they expected a chemical reaction that will likely cause a fire that will “resemble a large gasoline fire.” A threat of additional explosion remains. Residents living within a 1.5-mile (2.4km) radius of the plant had been evacuated amid fears of such an event. One police officer who was helping secure the site was taken to hospital after inhaling fumes, while nine others admitted themselves as a precaution.
