MEMPHIS, Tenn. (AP) — An oil refinery worker exposed to propane and acid at a Valero plant in Memphis died on Monday, officials said.

He was the second Valero worker to die this year from an on-the-job injury. A man died from injuries suffered in a March fire at the refinery, which has been cited for violations related to the safe handling and control of hazardous energy and chemicals, officials said.

Firefighters on Monday morning found two workers injured when a sight glass on a pump unit ruptured, exposing them to a mixture of propane and hydrofluoric acid, said Memphis Fire Department spokesman Wayne Cooke.

Two firefighters also were exposed to the substance, he said. The pump was located at the plant's alkylation unit, Valero Energy Corp. spokesman Bill Day said in a statement.

A sight glass is a transparent tube or window that allows workers to monitor fluid levels within a tank, pipe, pump or boiler.

One of the Valero workers died at the hospital, said Martha Deacon, a spokeswoman for the Tennessee Department of Labor and Workforce Development. She did not have details on the time or cause of the death. The other worker, who was a contractor, and the two firefighters were taken to a hospital in non-critical condition.

The company said there was no explosion or fire, and no refinery operations were affected. The refinery has notified regulatory agencies and the accident remains under investigation, Day said.

"Safety is always our most important concern, of course," Day said in an email. "Any incident of this type is too many, which is why we will investigate to find the root cause of this incident and take any appropriate steps to ensure the safety of our employees, our plants and our communities."
