| The statement goes on to say that although the plant followed hurricane preparation protocol, “unprecedented flooding overwhelmed our primary power and two sources of emergency backup power. As a result, we lost critical refrigeration of the products on site. Some of our organic peroxides products burn if not stored at low temperature.” | The statement goes on to say that although the plant followed hurricane preparation protocol, “unprecedented flooding overwhelmed our primary power and two sources of emergency backup power.

| The "pops" occurred inside one of nine box trucks at the site, according to Bob Royall, an assistant chief with the Harris County Fire Marshal's Office. | |
| "There are nine vans. Of the nine, three had lost refrigeration to keep them cool. the other ones are still under refrigeration," he said, adding that the chemicals are "in containers in cardboard boxes inside the vans." | "There are nine vans.

| “The fire will happen. It will resemble a gasoline fire. It will be explosive and intense in nature... as the temperature rises, the natural state of these materials will decompose. A white smoke will result, and that will catch fire. So the fire is imminent. The question is when,” spokesperson Janet Smith said. | “The fire will happen. It will resemble a gasoline fire.

| Organic peroxides are "relatively unstable compounds which can decompose spontaneously and sometimes explosively,"according to Arkema's Luperox website. They are "generally flammable and burn vigorously." | Organic peroxides are "relatively unstable compounds which can decompose spontaneously and sometimes explosively,"according to Arkema's Luperox website.
