Fire crews rushed to the scene of a reported explosion at a chemical plant in Freeport.
It happened around 7:30 p.m. Friday at the Dow plant at the intersection of Highway 332 and FM 523.
Freeport City Manager Jeff Pynes said the explosion was small, and no one was injured. Pynes said there's no threat to the community, and no shelter in place has been called.
A spokesperson for Dow said Emergency responders were on scene of what they described as an incident at the plant.
Officials with Dow later said there was no explosion at all. Instead, they said a safety device was responsible for making the loud noise.
The cause of the incident is under investigation.
