Investigators believe they've pinpointed the cause of an explosion and massive fire at a Pasadena plant on Wednesday -- and they say it was an accident.
One person was injured in the blast at about 12:07 p.m. at the INEOS Phenol plant along Highway 225 near the East Beltway. Houston TranStar cameras captured the large explosion and fireball. Smoke and flames could be seen from miles away.
Harris County Pollution Control said there weren't any impacts to air quality in the area.
"Fortunately, we have good wind blowing whatever was up high and aloft in the flame, and the fire, the smoke," Dr. Latrice Babin said. "So, we are not expecting there to be any impact."
One worker was hurt in the blast. The person was conscious, alert and stable at the hospital, according to Harris County Sheriff Ed Gonzalez.
There's no word on the individual's identity or the nature of any injuries. Everyone at the plant was accounted for, officials said.
