DONALDSONVILLE - CF Industries said a contract worker at their Donaldsonville nitrogen plant died Friday afternoon.

Company spokesperson Morris Johnson said they were notified a little after 1 p.m. that the worker was found unconscious in a vessel at a part of the facility which is under construction.

Johnson said the worker was taken to a local hospital where he later died. The company didn't identify the worker, but said he was employed by Sulzer contractors.

Sulzer issued a statement Saturday about the incident:

"Sulzer Chemtech is deeply saddened by the news of the loss of one of our employees on the afternoon of December 4, 2015. We offer our deepest sympathies to the family members of our lost colleague and friend. We are committed to offering our full support and assistance to family members to assist them in their time of need. Sulzer Chemtech is presently investigating the facts surrounding this event. In the interim, we ask that the family members privacy be respected during this most difficult time." 

The Ascension Parish Sheriff's Office and Louisiana State Police are investigating the worker's death.

Construction in the part of the facility where the worker was found was put on hold Friday, according to Johnson.

The CFI Plant in Donaldsonville is the largest producer of nitrogen in the nation, according to the company's website.
