About 200 Walker County residents near Huntsville spent most of the day holed up indoors because of a chemical leak.
Officials tell us at about 8:30 a.m. Friday, crews were called to investigate a suspicious odor coming from a Union Pacific tank car in the Phelps area.
Union Pacific says a gasket broke, causing sodium hydro sulfide to leak. The chemical can irritate the face.
Luckily, the chemical did not leak on the ground and no one was injured.
The tank car was repaired and residents were able to leave their houses about 11.
No environmental issues are expected to arise from the spill.
Authorities credit their Code Red System for getting all residents notified.
