Rescue 35 and Unit 15 were dispatched assisting Company 36 for a one vehicle MVC at Halls Hill Lane. While responding to this vehicle on its side call, crews were made aware of a second accident in the vicinity of the first accident. Upon arrival crews found dangerous conditions with blowing snow and near white-out conditions. The second accident involving a tanker transporting home heating oil and a pick-up truck resulted in an extended road closure. No fluids were lost from the tanker. Crews assisted with minor fluid control from the pick-up, and assisted with packaging patients for transport. Units 12, 15, and 16 transported patients. A special thank you to PennDOT for assisting on scene with salting and cindering, which assisted with detouring traffic.
