Two fire crews from Burnham-On-Sea were called to a blaze at an industrial unit on the Walrow Industrial Estate in Highbridge on Wednesday morning (January 24th).
Firefighters gained entry to the premises to find smoke billowing from an extractor unit.
Crews extinguished the fire using two hose reel jets and further investigations were carried out using a thermal image camera.
A spokesman told Burnham-On-Sea.com: “The cause of the fire was a hot, broken router blade in sawdust.”
