No one was injured.

Update: Thursday, Aug. 9 at 8:28 p.m.:

Five companies from across Jefferson City are responding to the PMI fire. A Cole County crew is there as well for mutual aid since so many fire fighters are working this one fire.

Fire Department spokesman Jason Turner said the retail area has suffered quite a bit of damage, and the fire is starting to move to the back area of the building where machines are stored.

Fire fighters are facing some concerns and challenges because of oxygen and propane tanks stored in the machine area, as well as a highly-flammable liquid used for torches and welding.

The owner of PMI left the business at about 6:15 Thursday night. About 20 minutes later an alarm went off. Jefferson City Police initially responded to the alarm. When they arrived and saw the fire, officers called in fire crews.

PMI employs about seven people.
