ROBINSON TOWNSHIP, Pa. — (WPXI) – Fire crews were called to a fire at an industrial site in Robinson Township on Sunday. According to responding crews, a passerby on Route 22 saw smoke billowing out of the huge commercial building after 1:30 this afternoon and called 911. The Midway fire chief says when crews first arrived, there was thick black smoke coming out of nearly every corner of the building. No one was inside the Costy’s Energy Services building when the fire started and there were no injuries. Costy’s is an equipment company that services the fracking industry. Firefighters say the greatest challenge they faced was just getting to the location. “The commercial building was approximately a mile off Steubenville Pike, down a gravel lane,” Midway Volunteer Fire Chief Doug Baird said. “We did have a hydrant near the scene, which we cut through property to get to, and had tanker shuttles from Washington County, Beaver County, Allegheny County and Pittsburgh International Airport.” Crews were able to knock down the majority of the flames down in an hour and a half but crews remained here on scene until about 5:30. We’re told that the fire marshal is investigating the cause of the fire.
