Hydrogen chloride (HCl) gas is one of the byproducts produced by the Space Shuttle solid-propellant rocket boosters. This report described a nonobtrusive absorption technique to measure concentrations of gaseous HCl for four days following Shuttle launches 41D and 51A at Kennedy Space Center (KSC). The peak concentrations measured near ground level about 400 m from the launch structure were found to be less than 10 ppm averaged over a 500-m path after both launches.
