A man critically injured in an explosion at a refinery in Wynnewood, Oklahoma, has died at the hospital on Tuesday.
The explosion occurred at approximately 6:20 p.m. on September 28, as operators were restarting a boiler that had been temporarily shut down as part of the refinery's turnaround process.
Thirty-four-year-old Billy Smith of Pauls Valley, Oklahoma, was killed in the blast. Russell Mann of Davis, Oklahoma, was transported to the OU Medical Center in critical condition following the explosion.
A spokesperson with the hospital confirmed that Mann died at the hospital on Tuesday.
This wasn't the first incident at the Wynnewood Refinery.
An explosion rocked the refinery in December of 2010. In April of 2008, a fire broke out as crews were working on a pipe. Two months before, a furnace caught fire.
In 2007, a lighting strike ignited more than 20,000 barrels of oil sending flames more than 60 feet into the air. And in 2006, there was an acid leak and fire.
No one was injured in any of those incidents.
