WILLIFORD, AR - An apparent transformer malfunction this evening at the Williford school campus caused a fire that resulted in a propane tank being punctured, prompting Sharp County authorities to ask residents there to evacuate the small town as a precuationary measure.
The accident happened shortly after 7 p.m. Firefighters at the scene say when the transformer exploded, it caused a nearby telephone pole to fall, which led to the puncture of the tank, thus igniting a fire and apparent propane leak. One firefighter with the Williford Volunteer Fire Dept. sustained minor injuries to her arm.
Propane is considered non-toxic, however, in certain situations it does pose a mile asphyxiation risk. It may also sometimes contain hydrocarbons beyond propane, which may increase risk.
