French chemical group Arkema has confirmed two explosions at its plant today in Crosby Texas, and added there was a risk of further explosions at the site.
Arkema said in a statement, “We want local residents to be aware that the product is stored in multiple locations on the site, and a threat of additional explosion remains.”
The company evacuated remaining workers at the damaged plant on Tuesday, and Harris County ordered the evacuation of residents within a 1.5-mile (2.4-km) radius of the plant, which makes organic peroxides used in the production of plastic resins, polystyrene, paints and other products.
Daryl Roberts, the company’s vice-president of manufacturing, technology and regulatory services in the Americas, said that the vessels containing the organic peroxide are equipped with controls to slow the release of chemicals. He said the chemicals will quickly vaporize because of the water, reducing the size and scope of the fire.
The Federal Aviation Administration has temporarily barred flights near the plant because of the risk of fire or explosion.
Arkema manufactures organic peroxides, a family of compounds used for making a variety of products including pharmaceuticals and construction materials.
