Things are back to normal after a fire breaks out at a Midland county business.
The Stewart and Stevenson Company evacuated more than 75 workers just after three Thursday afternoon along Highway 80.
The blaze began in a warehouse, just behind the main building.
Workers tell NewsWest Nine that a heater tank malfunctioned where employees clean engines and transmissions.
The thick black smoke billowed from the building for about half an hour.
The company uses chemicals in the cleaning process, but officials say they aren't considered dangerous, and no one was hurt.
