WINDSOR, Colo. — An investigation is underway after a worker at an oil site in northern Colorado was injured in an overnight fire that was brought under control Saturday.

It took several hours for firefighters to get a handle on the blaze and staff had to retreat at one point when the fire became too unstable, The Greeley Tribune reported .

The fire was extinguished by Saturday afternoon; residents first heard loud explosions around 8:45 p.m. on Friday.

The worker was taken to a nearby hospital with severe burns.

A spokesman for the oil and gas site owner Extraction Oil & Gas said the employee was in stable condition Saturday. The worker’s name hasn’t been released.

“Regrettably, an individual working onsite was injured at the onset and was taken to a local hospital,” company spokesman Brian Cain said. “He is recovering in stable condition and our thoughts are with him for a speedy recovery.”

The Weld County Sheriff’s Office said early evidence indicated that an industrial accident caused the fire, but the scene was turned over to the Windsor Fire Department for more investigation. A cause hasn’t been determined yet.

Windsor Severance Fire spokesman Todd Vess said crews checked air quality in the area throughout the fire and found “nothing to indicate any sort of dangerous levels at all.”
