On Tuesday, a mustard agent vapor was detected inside a chemical storage igloo at the Pueblo Chemical Depot.
Carbon filters stop contaminated air from leaving the structure. Crews will start to install air filters to lower the levels of contamination air inside the igloo, before sending crews in to search for the leak. They are expected go in Wednesday. There is no threat to the public.
