CHICAGO, Ill. --
An acid spill at a Chicago chemical company sent at least one person to the hospital and caused several others to get treatment for respiratory problems. Hazmat crews were called to two separate locations near the TBS Chemical Company in the 2900-block of East 126th Thursday afternoon. Firefighters say 30 gallons of sulfuric acid spilled. The acid caused a plume of smoke which may have drifted to the second location nearby.
