Around 0030 hours on March, 1st, Sarver Station 36, Buffalo Township Station 27, and Freeport EMS Station 70 were alerted for a vehicle accident with injuries at Butler Road near the Allegheny County line. Butler 911 advised that the vehicle was over a hillside. Lieutenant 36-2 arrived on scene shortly after Medic 70-3 and established Butler Road Command. Command advised all units that there was one vehicle about 150-175 feet over the hillside, and the vehicle was on its side. Rescue 36 marked en-route shortly after dispatch with a crew of 4. Command instructed Medic 70-2 and Captain 27 to check for better access from either the Rails to Trails or from Coal Street in Butler Junction. Both units advised that there was no access. Rescue 36 arrived on scene and Captain 36 assumed Butler Road Command as Lieutenant 36-2 proceeded down the hill, to the vehicle, to advise further. Harrison Hills Station 169 in Allegheny County was requested to assist with their Rescue for manpower. EMS Command also requested Freeport Rescue 70 in Armstrong County and Citizens Rescue 167 from Allegheny County. Lieutenant 36-2 advised command that there was entrapment and the roof needed to be removed to access the driver but the passenger self extricated from the vehicle. Shortly after struts were brought to the vehicle, the victim was removed from the vehicle without the use of hydraulic tools. Rope Rescue operations were set up at the top of the hill to safely bring the patients to the emergency crews. A 3 to 1 system was constructed and a Stokes Basket was lowered down the steep hillside on a 300 foot section of rope. Lieutenant 36-2 and Chief 36-2, assisted by two firefighters from 169 Rescue, safely secured the patients in a Stokes Basket and safely extricated them up over the hillside one at a time. When both patients were in EMS care, Rescue 70, Rescue 167, and Engine 27 were released. Rescue 36, Brush 36, Rescue 169, and Fire Police 27 remained on scene for lighting and traffic control until the vehicle was removed by the tow company. Command was terminated approximately 3 hours after dispatch.
