This report presents the results of hydrochloric acid HC1 measurements accomplished following the launch of Space Shuttles 5, 6 and 7 from launch complex 39, pad A, at the Kennedy Space Center KSC. The objective of the sampling program was to evaluate the potential for revolatilization of HC1 deposited in the vicinity of the launch complex and to determine the time history of the event if it occurred. The data collected during the program demonstrate that HC1 can persist for several hours following Shuttle launch and that there is potential for isolated higher levels of HC1 to occur. The data also provide insight to the magnitude of HC1 concentration variability which can be influenced by meteorological, topographical and operational parameters. The relative importance of these parameters can be shown to have a major influence on HC1 concentrations and will likely be superimposed on any revolatilization or concentration decay curve. The importance of even low level HC1 concentrations on pad reentry personnel is discussed however, the potential effect on electronic equipment and circuitry remains to be addressed. Author
