A Gothenburg man has been freed after being trapped in a grain bin for four hours.

Rick Frickenstein was reportedly near the bottom of the bin at All Points Cooperative, trying to unplug an auger, when he was covered with grain, according to officials with the Gothenburg Fire Department.

Frickenstein was able to call for help using his cell phone, and rescuers arrived on scene at approximately 9:30 a.m.

Firefighters used climbing gear to get to Frickenstein who was buried up to his armpits.

Rescuers worked feverishly to remove pressure from the grain.  They then strapped webbing around Frickenstein’s chest with a rope and vacuumed out the grain.

Frickenstein was taken to Gothenburg Memorial Hospital for observation, but didn’t appear to have injuries, according to authorities.

The All Points elevators were the site of an explosion in December of 2010.
