Potential chemical explosion at flooded Texas plant prompts evacuation

AOL

WASHINGTON (Reuters) – Arkema SA expects chemicals to catch fire or explode at its heavily flooded plant in Crosby, Texas in the coming days, and has no way to prevent that from happening, the chief executive officer of the company’s North America unit said on Wednesday.

The company evacuated remaining workers on Tuesday and Harris County ordered the evacuation of residents in a 1.5-mile(2.4-km) radius of the plant that makes organic chemicals.  

Richard Rowe, chief executive officer of the North America unit, told reporters that chemicals on the site will catch fire and explode if they are not properly cooled, and that Arkema expects that to happen within the next six days as temperatures rise. He said the company has no way to prevent that because the plant is swamped by about six feet (1.83 m) of water.

Rowe said the company was “comfortable” with the size of the evacuation zone.

Rowe did not disclose the volume of chemicals on the site and said it was speculative to predict how much damage the plant could sustain. He said there could be an “intense fire” that would result in significant black smoke but would not pose any “long-term harm or impact.”

The plant is near a section of Interstate-90 that has been underwater and closed.

The plant has been without electric service since Sunday. Back-up generators have largely been inundated with water, the company said.

Chemicals on site are stored at low temperatures and can catch fire or explode at higher temperatures. The plant lost refrigeration when backup generators were flooded and then workers transferred products from the warehouses into diesel-powered refrigerated containers. The company said some refrigeration of back-up containers has been compromised because of high-water levels and the company is monitoring temperature levels remotely.

The Federal Aviation Administration has temporarily barred flights over the area near the plant because of the risk of fire or explosion.

Harvey, which came ashore in Texas last week as a powerful Category 4 hurricane, has caused catastrophic flooding.

Other chemical plants have also shuttered production in Texas because of the hurricane.

  1. “It would be surprising if the company had not considered as scenario like this, said Sam Mannan of Texas A&M University’s Mary Kay O’Connor Process Safety Center.
    Companies typically would have the ability to quench the organic peroxides in situations like this with another chemical so it’s no longer dangerous.
    ‘You’ll lose the feedstock but it’s safer than letting it go into runaway mode,’ Mannan said.”
