"Several hundred people have been evacuated from a section of Lubbock, Texas, after a leaking tank released a chemical that could turn into highly corrosive hydrochloric acid, the city's Fire Department said on Thursday."
"No injuries were reported after emergency officials set up a 4-mile-wide (6.4-km-wide) exclusion zone in a sparsely populated area northeast of the city to allow a specialized team from Dallas to transfer the chemical from a cracked 3,000 pound (1361 kg) tank into a new vessel.
The incident occurred at Bayer Crop Science facility. Bayer Crop Science is a unit of Bayer AG.
The tank contained hydrogen chloride, which reacts with moisture in the atmosphere to form hydrochloric acid when released, the fire department said."
