Yesterday we reported, that in a potentially disastrous outcome from the Harvey flooding, a chemical plant in Crosby, Texas belonging to French industrial giant Arkema SA, has announced it is evacuating workers due to the risk of an explosion, after primary power was knocked out and flooding swamped its backup generators. The French company said the situation at the plant “has become serious” and said that it is working with the Department of Homeland Security and the State of Texas to set up a command post in a suitable location near our site.

The plant, which produces explosive organic peroxides and ammonia, was hit by more than 40 inches of rain and has been heavily flooded, running without electricity since Sunday. The plant was closed since Friday but has had a skeleton staff of about a dozen in place. Following the flood surge, the plant's back-up generators also failed. The threat emerged once the company could no longer maintain refrigeration for chemicals located on site, which have to be stored at low temperatures. The plant lost cooling when backup generators were flooded and then workers transferred products from the warehouses into diesel-powered refrigerated containers.
On Tuesday afternoon, the company released a statement which admitted that "refrigeration on some of our back-up product storage containers has been compromised due to extremely high water, which is unprecedented in the Crosby area. We are monitoring the temperature of each refrigeration container remotely." It then warned that “while we do not believe there is any imminent danger, the potential for a chemical reaction leading to a fire and/or explosion within the site confines is real."
One day later, and with the torrential rains finally over, has the situation at the giant peroxide chemical plant stabilized? Unfortunately, according to Reuters, the answer is no.
Speaking to reporters on Wednesday afternoon, Richard Rowe, the chief executive of Arkema's American operations said that "the company has no way of preventing chemicals from catching fire or exploding at its heavily flooded plant." Rowe added that the company now expects chemicals on site to catch fire or explode within the next six days. Since the plant remains flooded by about six feet of water, "the company has no way to prevent" this worst-case outcome.
Anticipating the worst, the company earlier evacuated all remaining workers, while Harris County ordered the evacuation of residents in a 1.5-mile radius of the plant that makes organic chemicals.
Previously, Arkema said that it was working with Homeland Security and the state of Texas to set up a command post near the site. As we reported on Tuesday, Rep. Ted Poe, a Texas Republican, wrote on Twitter that the Crosby plant "is in danger of fire/explosion. The local area is being evacuated. Stay out of area."

Previously Reuters added that other chemical plants have also shuttered production in Texas because of the hurricane, however none are in such a precarious state. These include Anglo-Swiss chemicals firm Ineos Group Holdings, which said it has been forced to shut down facilities in Texas. Chocolate Bayou Works and Battleground Manufacturing Complex, and INEOS Nitriles’ Green Lake facility are following hurricane procedures and are temporarily shut down, spokesman Charles Saunders said. Huntsman Corp said it has closed six chemical plants in Texas, along with its global headquarters and advanced technology center in Texas.
