A fire at NTN Driveshaft was put out quickly by plant personnel at 10:35 a.m. Tuesday, Columbus firefighters said.
The fire was first reported in the south forge area of the plant and was out when firefighters arrived. Plant workers evacuated for about 15 minutes, said Capt. Mike Wilson, Columbus Fire Department spokesman.
NTN maintenance supervisor Steve Bushee said the fire was caused by a flame-retardant cover that ignited from oil and carbon buildup. The cover separates the entrance of a press from the machine’s conveyor system.
Bushee explained that the product that enters the press is extremely hot. High temperatures and buildup of combustible materials ignited part of the protective cover, causing the fire, he said.
The fire was put out quickly, but he believed that a small piece of the cover material had burned free and was sucked into the machine’s vent duct. Bushee said that the duct system is equipped with heat sensors as well as a fire-suppression system. He said the fire alarm was activated from the temperature sensors in the duct.
No injuries were reported in the incident.
