A worker at a Halloween attraction in Sperry was taken to the hospital Saturday afternoon in critical condition, after an explosion.

The explosion happened around 12:30 p.m., at the Psychopath attraction.

A Sperry Fire Department official says the worker tried to use a blow torch to open a 55 gallon drum.  The barrel wasn't labeled and exploded.

An official with the attraction tells us the incident happened in a barn where customers are not allowed. 

The victim was transported to a hospital in Tulsa.  An update on his condition hasn't been released. 

So far, the worker's name also hasn't been released.
