Mustard agent leaks at Tooele depot, so workers decontaminate the area

Workers at Deseret Chemical Depot in Tooele County this week detected deadly mustard agent in a storage igloo. The workers entered the filtered igloo and discovered a residue that had leaked from a weapons   projectile and then dried, said depot spokesperson Alaine Southworth. Crews decontaminated the area and packed the leaking projectile into an airtight container for continued storage.
