(KSL News) -- Safety concerns surrounding a deadly nerve agent at the Army Incinerator in Tooele County have prompted officials to temporarily stop moving that nerve agent from a storage area.
An Army contractor has offered no explanation.
But the state's top regulator tells Eyewitness News "They're just being super cautious."
He says concerns came up during an investigation into an employee who is accused of improperly reducing the sensitivity of nerve agent monitoring equipment.
No word yet on how long the interruption will last.
