Subcontractors working at Fukushima Daiichi reported a fire near Units 5 and 6 around 11:20 am Wednesday morning. The workers were working on a welding operation to complete plumbing for fire extinguishing equipment near the Number 3 light oil tank.
TEPCO reported that the workers had laid down fire protection sheets to cover the ground to prevent any excursions, but that the strong coastline winds had pushed the sparks to uncovered areas. The workers reported they were able to extinguish the flames after 15 minutes, and at 1:13 pm firefighters from the Name fire department confirmed the fire was put out.
Work on site at Fukushima Daiichi is still critical, as an unprecedented setback could potentially hinder efforts to keep the reactors cool. All fire related events must be handled carefully as the radioactive materials on-site in the soil and plants can be released into the air with the smoke and pose a potential threat to other workers not in the immediate vicinity.
