Maritime transport of liquid anhydrous ammonia LNH3 poses a potential hazard to the public, to aquatic life, and to other shipping should there be an accidental surface or underwater release of ammonia. This report contains the results of an experimental and analytical program aimed at evaluating the hazards presented by a 3,000 ton release of liquid anhydrous ammonia on water. Test spills were conducted in the laboratory up to 12 gallons, in a swimming pool 5 gallons and in a lake 50 gallon size and the fraction of released ammonia dissolving in water and the amount vaporizing were determined. The dispersion of vapor in air was measured and a theory was developed to predict the movement. Analytical models to predict water dispersion are also presented.
