Valhalla and Elmsford Fire Departments were dispatched to the Sprain Brook Parkway just south of Hospital Rd for an MVA with injuries. When crews arrived all occupants were out of the vehicle with County EMS tending to the patient. With 37M1 triaging patients, ambulances from Hawthorne, Elmsford, Grasslands Campus and the County AMR unit were requested. While EMS units were tending to the patient FD crews secured power to the vehicles and mitigated the fluid spills. After all patients were off the scene and vehicles were removed units were placed back into service.
