Mustard agent vapor was detected Tuesday during a routine weekly chemical monitoring check at the Pueblo Chemical Depot, a chemical weapons storage site associated with the U.S. Army.
The agent vapor was detected inside an igloo storing 105 mm projectiles. A chemical crew dressed in personal protective equipment are planning to enter the igloo in order to perform a visual inspection. The crew is looking for actual agent leakage.
County and state officials have been notified. More information will be provided as soon as it’s available.
