Five workers at the Anniston Army Depot's chemical weapons stockpile were tested for nerve agent exposure Monday after an alarm detected trace amounts of sarin while they were inspecting a bunker.
Those tests came back negative Tuesday, indicating that none of the workers were exposed.
The bunker houses M55 rockets containing the nerve agent GB, also known as sarin. An air monitor did not detect nerve agent in the bunker before the workers began their operations Monday. Nor did the workers find any signs of a leak during the visual inspection.
The crew had removed their gas masks as they had finished the visual inspection and were waiting to begin inspections of the individual rockets when the alarm sounded. They evacuated the bunker and closed the door. At the time, none of the crew showed signs of nerve agent exposure. As a precaution, they all received blood tests Monday.
According to the Army, no agent was detected outside of the igloo and there was no danger to the community outside of the depot.
