Just after dinner from Spring Ridge Fire Station 33 and Rescue Squad 3 were alerted for auto accident at Spring Ridge Parkway and Route 144. Battalion 901 E331 and A339 arrived on scene to find several vehicles in the roadway with no entrapment but several patients. The Battalion Chief established RT144 command and requested a second BLS. Carroll County PM19 was returning to quarters from FMH and was added to the call due to their location to the scene. The rescue was held to help with patient care and fluid control that was leaking from the vehicles. The units cleared after all patients were packaged and transported
