Dugway Proving Grounds, a Utah military base responsible for testing chemical weapons, was locked down 12 hours overnight and reopened today after a vial of nerve agent was misplaced. Officials from the base issued a statement Thursday stating that the 1/4 teaspoon amount of the VX nerve agent went missing at the military compound located 85 miles southwest of Salt Lake City. Incoming personnel and the 1,200 to 1,400 civilians, contractors, and military personnel within the base were unable to enter or leave until the vial was found. Dugway spokeswoman Paula Thomas reported no injuries resulted from the cause of the lockdown.
The base is a 800,000 acre compound described as the "Defense Department's leader in testing battlefield smokes and obscurants." The U.S. Army Reserves and the U.S. National Guard often do maneuver training at the compound.
