Emergency officials in Iowa County say it’s a mystery as to what caused 15 illnesses at Cummins Emission Solutions. Keith Hurlbert, director of Iowa County Emergency Management, says a gas leak actually happened on Tuesday. Wednesday night’s call about a gas leak was actually about high carbon monoxide levels. Hurlbert says officials did not find a gas leak on Wednesday. What they did find were high levels of carbon monoxide registering on their meters,. He says a construction crew hit a natural gas line on Tuesday. After that, the line was shut off. On Wednesday, a call came in for a gas leak at about 6:00 p.m. When officials arrived, they realized it was not a gas leak, but instead high levels of carbon monoxide. Officials believe the high levels stemmed from the forklift battery charging stations.
