A Fairborn firefighter-paramedic driving a suspected overdose patient to the hospital Thursday night began showing symptoms of an overdose himself, prompting his partner to jump into action and stop the ambulance in the middle of the road. This is the latest — and perhaps most dramatic — case of a public safety employee exposed to an opioid. “He was not feeling right. He was having issues seeing the speedometer controls,” said David Reichert, division chief for Fairborn fire. “His partner in the back was immediately able to stop the medic in the middle of an intersection.”
