Fire evacuates Cobb County business, sends 3 to hospital

Fire investigators are working to figure out what sparked a small fire that forced an evacuation at a Cobb County business.

Crews were called to Cryolife on Roberts and Barrett Park Drive Tuesday morning before 10.

Officials say the building's sprinkler system put out the fire, but HAZMAT crews were called in because the building housed chemicals.

Three employees were taken to the hospital for evaluation.
