Vertical air turbulence is reduced directly over dense gas pooling events, such as large releases of chlorine. This phenomenon was witnessed during the Jack Rabbit test program, which was conducted at Dugway Proving Ground (DPG), UT in April/May 2010. Because of the lower turbulence, air entrainment and/or chemical detrainment is lessened within the dense gas pool. Information such as this is important for a better understanding of how to respond to accidental releases of hazardous chemicals, like the many toxic industrial chemicals / toxic industrial materials (TIC/TIM) that are transported in the United States every day. This presentation will summarize the wind turbulence directly over the dense gas pooling of the Jack Rabbit test program. Differences in low wind and high wind trials from the test program will be compared. Lastly, the importance of Jack Rabbit test results will be discussed.
