Battalion Chief Jim Vaughn demonstrates Thursday how the exhaust ventilation hose attaches by magnet to an ambulance’s exhaust pipe at Fire Station No. 1 in Springdale. The department installed the system more than a year ago to more effectively ventilate the station from fumes emitted by the diesel-engine vehicles used by the department.
