| 摘要： | During the period of 1990 to 2000, 111 carbon monoxide (CO) poisoning cases occurred on Lake Powell near the border of Arizona and Utah. Seventy-four of the poisonings occurred on houseboats, and sixty-four of the poisonings were attributable to generator exhaust alone. Seven of the 74 houseboat-related CO poisonings resulted in death. In February 2001, the National Institute for Occupational Safety and Health (NIOSH) conducted an initial evaluation of an engineering control installed on a houseboat generator to reduce the hazard of CO poisonings from the generator exhaust. The control consisted of a water separator and an exhaust stack that extended 9 feet above the top deck of the houseboat outfitted onto a gasoline-powered generator. This previous investigation, conducted at Lake Powell, showed substantial reductions (greater than 99%) in the concentration of CO on and around the swim platform of a Lakeview houseboat retrofitted with the 'dry stack' generator exhaust system. The Lake Powell evaluation was conducted on a single stationary boat docked under moderate ambient temperature and wind conditions. The current study investigated the effect of additional variables on the performance of the dry stack exhaust system. These variables included elevated ambient temperature, boat in motion, and the effect of tying two or more boats together. Alternative configurations including side and rear exhaust were also tested for comparison with the dry stack. |
