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.
