Firefighters had to extricate a worker who suffered life-threatening injuries after his arm became trapped inside a large machine near Woodstock.

The Woodstock Fire-Rescue District responded around 7:41 a.m. Wednesday to Wheeling Service and Supply, 15920 Nelson Road in unincorporated Woodstock.

Dispatchers received a 911 call for an adult male whose arm was trapped inside an industrial machine inside the building, according to the fire district.

Due to the complexity of the machine, an “elongated and meticulous” extrication process took place to free the victim’s arm.

Once free of the machine, paramedics transported him to Northwestern Medicine McHenry Hospital with life-threatening traumatic injuries.

A medical helicopter had initially been requested to the scene but they declined to fly due to weather conditions, the fire district said.

No additional details have been released on how the man’s arm became stuck or if an investigation is underway.
