Officials say flames broke out at Flowchem along FM 529 west of FM 2855 at around 9:30pm. Though a test of the air quality showed only a low risk, residents near the facility were advised to shelter-in-place. That order was lifted at around 2:20am.
At this point, it's not clear how the fire started. Plant managers say there haven't been employees there since Thursday.
Waller County Judge Trey Duhon said, "There's definitely some alcohol and some other materials on site that were flammable, and we know that there was one tank that had liquid nitrogen in it that we were real careful of, but it doesn't appear the fire came anywhere near close to those tanks."
Air tests of the area did not show any danger from the fire.
According to the Waller County Sheriff's Office, Flowchem makes a pipeline additive that uses ground up synthetic rubber and soybeans.
