Abstract:

The Chicago Sanitary and Ship Canal CSSC has electric dispersal barriers in operation to prevent the spread of aquatic nuisance species. The experiment was to better understand what would actually occur during a rescue in the electrified waters with three barriers energized. An additional purpose was to identify any methods, devices, or operating guidance to prevent potential harm to a rescuer. Voltage measurements under controlled conditions were taken during transits in the regulated navigation area using aluminum and fiberglass-hulled vessels to determine the current a rescuer would be exposed to. Monitoring of voltage levels and vessel position continuously took place throughout the transit. Devices evaluated for potential rescuer use included life ringsthrow lines and non-conducting boat hooks. Measurements taken along the canal bank assisted in determining currents a rescuer from shore would experience. Under certain operating conditions and with non-conductive apparatus, rescuers may be able to safely assist person in the water to move them away from the barriers. The rescuer and victim must be isolated from a vessel metal hull for recovery, and use of a fiberglass-hulled vessel provides improved protection over an aluminum-hulled vessel. Some areas of the canal upstream of Barriers IIA and IIB may support a shore-side rescue.
