STRINGTOWN, Okla. – A tanker truck delivering gasoline to Mack Alford Correctional Center exploded at a fueling station Friday on the medium-security prison’s grounds.

The explosion happened just after noon Friday at Oklahoma Correctional Industries (OCI), but thankfully no one was injured.

Staff and inmates working at OCI were moved away from the area.

“It’s a blessing that no one was hurt in this accident,” ODOC Director Joe M. Allbaugh said. “This was a violent explosion.”

The explosion blew debris onto the median of U.S. 69, the highway that runs along the prison’s east side.

Multiple local fire departments, emergency crews, and law enforcement responded to extinguish the blaze and assist with the scene.
