Nerve gas accident |
Nerve gas accident In 1968, a sudden outbreak of startling sheep deaths in Skull Valley, Utah, was attributed to a nerve gas sprayed earlier by the Army on the nearby Dugway Proving Grounds. The investigation made by the National Communicable Disease Center was hampered by the Army's initial denial of responsibility and slowness to provide adequate gas samples for independent agencies to check. The debacle led to an overhaul of procedures concerning development of chemical weapons at Dugway. |
