The Dalton Fire Department responded to a small fire at an industrial site at 310 Brookhollow Industrial Boulevard on Wednesday.
There is a small release valve from a propane tank that was apparently struck by lightning and a flame is showing at the top.
The fire department evacuated an 800 meter area around the structure as a precaution.
At this time, crews are letting the material burn off while monitoring for safety.
No one has been injured and there is no apparent damage at this point.
