From the Crystal Lake Fire Department:

On March 18, 2019 at 2:54 pm, the Crystal Lake Fire Rescue Department responded for a reported structure fire at 6207 Commercial Rd in Crystal Lake. Initial arriving crews, at 2:58 pm, reported heavy black smoke coming from the business (Diesel Redemption).  The caller had reported the business was working with a cutting torch and that the building was on fire. Fire units quickly switched to a defensive mode, operating from the outside of the building using hose lines and three ladder trucks. There were no injuries to the occupants or firefighters.

Mutual aid agencies were called to assist Crystal Lake utilizing the Mutual Aid Box Alarm System (MABAS). Crystal Lake command requested a third alarm.

A firewall in the center of the structure held the fire from spreading throughout the entire building which did not have fire sprinklers. A roof collapse and partial wall collapse were sustained in the area where the fire started.

The fire was deemed under control at 4:19 pm. Crews remained on scene extinguishing hot spots. Fire investigators from Crystal Lake and surrounding communities plus the Office of the State Fire Marshal are investigating the cause of the fire. A damage estimate is not yet available.
