CF Industries Holdings Inc., the largest U.S. producer of nitrogen fertilizer, said one person died and seven were injured after a blast at a plant in Donaldsonville, Louisiana.
Six of the seven workers were treated and released, while one remains hospitalized in stable condition, the company said in an e-mailed statement today.
CF Industries said the accident happened about 6 p.m. local time when an inert nitrogen vessel ruptured during the off-loading of nitrogen. The incident occurred in a part of the plant that had been shut for maintenance, and there was no fire or chemical release.
Ammonia and other nitrogen fertilizers are made at the plant, which is about 66 miles (106 kilometers) northwest of New Orleans. Nitrogen fertilizer is added to soil to provide nutrients that aid plant growth.
The company said it’s investigating the incident, along with local and regulatory authorities, including the Occupational Safety and Health Administration.
The accident came just days after an explosion at a Williams Cos. chemical plant in Geismar, Louisiana, which killed two workers and left 77 people seeking medical treatment.
An April 17 blast at a fertilizer plant in West, Texas, killed 14 people and injured more than 200, the nation’s worst industrial accident since 2010.
CF Industries is based in the Chicago suburb of Deerfield.
