| 摘要： | The researchers evaluated carbon monoxide (CO) emissions and exposures from two 2005 Centurion Avalanche ski boats equipped with carbureted inboard engines. One of the boats evaluated was equipped with the Sideswipe exhaust system, while the other was equipped with transom stern exhaust. In the Sideswipe exhaust system the engine exhaust is discharged from the sides of the boat instead of the stern. This investigation builds upon a series of recent studies to reduce CO exposures and poisonings on houseboats and other recreational boats. This study was performed for the U.S. Coast Guard for three purposes: to serve as an independent evaluation of the Sideswipe exhaust system, to gather additional data building upon previous studies related to CO concentrations and exposures near ski boats operating under various conditions, and to collect personal exposure data on an individual performing wake surfing. Ski boats, one with Sideswipe exhaust and one with stern exhaust, were evaluated both while stationary and while moving at multiple speeds ranging from 2.5 to 20 miles per hour (mph). CO concentrations were measured by multiple real-time instruments, placed at different locations on the boats and at various distances (10 to 60 feet) behind the boat in motion. |
