Question: The Pueblo Chemical Agent-Destruction Pilot Plant is what that contains the prototypical substance of the sulfur-based family of cytotoxic and vesicant chemical warfare agents known as the sulfur mustards which have the ability to form large blisters on exposed skin and in the lungs?

full_context: Document 1: Adamsite: Adamsite or DM is an organic compound; technically, an arsenical diphenylaminechlorarsine, that can be used as a riot control agent. DM belongs to the group of chemical warfare agents known as vomiting agents or sneeze gases. First synthesized in Germany by Heinrich Otto Wieland in 1915, it was independently developed by the US chemist Roger Adams (for whom it is named) at the University of Illinois in 1918.
Document 2: HN3 (nitrogen mustard): Tris(2-chloroethyl)amine is the organic compound with the formula N(CHCHCl). Often abbreviated HN3, it is a powerful blister agent and a nitrogen mustard gas (although it is not a gas) used for chemical warfare. HN3 was the last of the nitrogen mustard agents developed. It was designed as a military agent and is the only one of the nitrogen mustards that is still used for military purposes. It is the principal representative of the nitrogen mustards because its vesicant properties are almost equal to those of HD and thus the analogy between the two types of mustard is the strongest. As a vesicant the use and production is strongly restricted within the Chemical Weapons Convention where it is classified as a Schedule 1 substance.
Document 3: Tooele Chemical Agent Disposal Facility: The Tooele Chemical Agent Disposal Facility (also called Tooele Chemical Demilitarization Facility) or TOCDF, is a U.S. Army facility located at Deseret Chemical Depot in Tooele County, Utah that was used for dismantling chemical weapons. Destruction is a requirement under the Chemical Weapons Convention and is monitored by the Organisation for the Prohibition of Chemical Weapons. Deseret Chemical Depot held 44% of the nation's chemical stockpile when processing began, and it had held some of these chemical munitions since 1942. TOCDF was constructed in the early 1990s and began destruction of chemical agent-filled munitions on 22 August 1996. As of September 2011, the facility had processed 99% of its stockpile. TOCDF processed all of its VX, Sarin and mustard gas at its main facility; a smaller incinerator was installed west of the main plant in order to dispose of Lewisite-filled containers. In advance of plant closing, two ponds were revitalized and the surrounded area reseeded as well as 29 miles of railroad being removed (out of 40-miles of rail in Deseret). Disposal of all chemical weapons concluded on 21 January 2012. It was the last depot to complete its disposal operations under the U.S. Army Chemical Materials Agency; although two other depots still store chemical weapons to be destroyed by the Assembled Chemical Weapons Alternatives program at Pueblo, Colorado and Bluegrass, Kentucky.
Document 4: Blue Grass Chemical Agent-Destruction Pilot Plant: The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is a chemical weapons destruction facility undergoing systemization, or testing. The plant will destroy the chemical weapons stockpile at the Blue Grass Army Depot (BGAD), near Richmond, Kentucky. The plant is dedicated to the destruction of 523 ST of nerve agents sarin (GB) and VX, and mustard agent, which constitute about two percent of the United States chemical weapons stockpile.
Document 5: Blister agent: A blister agent, or vesicant, is a chemical compound that causes severe skin, eye and mucosal pain and irritation. They are named for their ability to cause severe chemical burns, resulting in painful water blisters on the bodies of those affected. Although the term is often used in connection with large-scale burns caused by chemical spills or chemical warfare agents, some naturally occurring substances such as cantharidin are also blister-producing agents (vesicants). Furanocoumarin, another naturally occurring substance, causes vesicant-like effects indirectly, for example, by increasing skin photosensitivity greatly. Vesicants have medical uses including wart removal but can be fatal if even small amounts are ingested.
Document 6: Blue Grass Army Depot: Blue Grass Army Depot (BGAD) is a U.S. Army storage facility for conventional munitions and chemical weapons. The facility is located in east central Kentucky, southeast of the cities of Lexington and Richmond, Kentucky. The 14494 acre site, composed mainly of open fields and wooded areas, is used for munitions storage, repair of general supplies, and the disposal of munitions. The installation is used for the storage of conventional explosive munitions as well as assembled chemical weapons. The depot primarily is involved in industrial and related activities associated with the storage and maintenance of conventional and chemical munitions.
Document 7: Nitrogen mustard: Nitrogen mustards are cytotoxic chemotherapy agents derived from mustard gas. Although their common use is medicinal, in principle these compounds can also be deployed as chemical warfare agents. Nitrogen mustards are nonspecific DNA alkylating agents. Nitrogen mustard gas was stockpiled by several nations during the Second World War, but it was never used in combat. As with all types of mustard gas, nitrogen mustards are powerful and persistent blister agents and the main examples (HN1, HN2, HN3, see below) are therefore classified as Schedule 1 substances within the Chemical Weapons Convention. Production and use is therefore strongly restricted.
Document 8: Pueblo Chemical Agent-Destruction Pilot Plant: The Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) is a chemical weapons destruction facility that has been built to destroy the chemical weapons stockpile at the Pueblo Chemical Depot, in southeastern Colorado. The depot contains munitions that are part of the U.S. national chemical weapons stockpile. Before chemical weapons disposal began at PCAPP, these munitions contained 2,613 U.S. tons of mustard agent. The weapons have been stored at the 23000 acre depot since the 1950s.
Document 9: Destruction of chemical weapons: Throughout history, chemical weapons have been used as strategic weaponry to devastate the enemy in times of war. After the mass destruction created by WWI and WWII, chemical weapons have been considered to be inhumane by most nations, and governments and organizations have undertaken to locate and destroy existing chemical weapons. However, not all nations have been willing to cooperate with disclosing or demilitarizing their inventory of chemical weapons. Since the start of the worldwide efforts to destroy all existing chemical weapons, some nations and terrorist organizations have used and threatened the use of chemical weapons to leverage their position in conflict. Notable examples include the use of such weapons by Iraq’s Saddam Hussein on the Kurdish village Halabja in 1988 and their employment against civilian passengers of the Tokyo subway by Aum Shinrikyo in 1995. The efforts made by the United States and other chemical weapon destruction agencies intend to prevent such use, but this is a difficult and ongoing effort. Aside from the difficulties of cooperation and locating chemical weapons, the methods to destroy the weapons and to do this safely are also a challenge.
Document 10: Sulfur mustard: Sulfur mustard, commonly known as mustard gas, is the prototypical substance of the sulfur-based family of cytotoxic and vesicant chemical warfare agents known as the sulfur mustards which have the ability to form large blisters on exposed skin and in the lungs. They have a long history of use as a blister-agent in warfare and along with organoarsenic compounds are the most well-studied such agents. Related chemical compounds with similar chemical structure and similar properties form a class of compounds known collectively as sulfur mustards or mustard agents. Pure sulfur mustards are colorless, viscous liquids at room temperature. When used in impure form, such as warfare agents, they are usually yellow-brown and have an odor resembling mustard plants, garlic, or horseradish, hence the name. The common name of "mustard gas" is considered inaccurate because the sulfur mustard is not actually vaporized, but dispersed as a fine mist of liquid droplets. Sulfur mustard was originally assigned the name LOST, after the scientists Wilhelm Lommel and Wilhelm Steinkopf, who developed a method of large-scale production for the Imperial German Army in 1916.
Document 11: Pine Bluff Arsenal: The Pine Bluff Arsenal (PBA) is a US Army installation located in Jefferson County, Arkansas, just northwest of the city of Pine Bluff. PBA is one of nine Army installations in the United States that stored chemical weapons. PBA supplies specialized production, storage, maintenance and distribution of readiness products, and delivers technical services to the Armed Forces and Homeland Security. PBA also designs, manufactures and refurbishes smoke, riot control, and incendiary munitions, as well as chemical/biological defense operations items. It serves as a technology center for illuminating and infrared munitions and is also the only place in the Northern Hemisphere where white phosphorus munitions are filled. Its Homeland Security mission includes first-responder equipment training and surveillance of prepositioned equipment.
Document 12: Mustard oil bomb: The mustard oil bomb is a chemical herbivory defense system found in members of the Brassicaceae (or cabbage family). The mustard oil bomb requires the activation of a common plant secondary metabolite, glucosinolate, by an enzyme, myrosinase. The defense complex is typical among plant defenses to herbivory in that the two molecules are stored in different compartments in the leaves of plants until the leaf is torn by an herbivore. The glucosinolate has a β-glucose and a sulfated oxime. The myrosinase removes the β-glucose to form mustard oils that are toxic to herbivores. The defense system was named a "bomb" by Matile, because it like a real bomb is waiting to detonate upon disturbance of the plant tissue.
Document 13: Pueblo Depot Activity: Pueblo Depot Activity "(PUDA)", formerly known as the Pueblo Ordnance Depot and the Pueblo Army Depot, was a U.S. Army ammunition storage and supply facility. Responsibility for the depot fell upon the U.S. Army Ordnance Corps, and the first civilians were hired in 1942 as operations began. The mission quickly expanded to include general supplies as well. It is a 24202 acre site located 14 mi east of Pueblo, Colorado. In 1945 they began to receive mass amounts of equipment returning from the combat theaters of World War II. Therefore, the mission expanded yet again to include the maintenance and refurbishing of artillery, fire control, and optical material. In 1951 the depot assumed responsibility to distribute U.S. Air Force ammunition for an eight-state area, as well as storage of strategic and critical materials for the General Services Administration (GSA). They were also tasked to rebuild and provide on-site maintenance support for guided missiles, ensure calibration and maintenance of electronic test equipment and radio-controlled aerial targets. They would also provide specialized training for new Army equipment as needed. In 1952, Rocky Mountain Arsenal in Denver, Colorado transferred chemical agents and chemical munitions to Pueblo Army Depot for secure storage. In 1974 Pueblo Army Depot was redesignated as Pueblo Depot Activity.
Document 14: Chemical weapons in World War I: Although the use of toxic chemicals as weapons dates back thousands of years, the first large scale use of chemical weapons was during World War I. They were primarily used to demoralize, injure, and kill entrenched defenders, against whom the indiscriminate and generally very slow-moving or static nature of gas clouds would be most effective. The types of weapons employed ranged from disabling chemicals, such as tear gas, to lethal agents like phosgene, chlorine, and mustard gas. This chemical warfare was a major component of the first global war and first total war of the 20th century. The killing capacity of gas was limited, with only about ninety thousand fatalities from a total of some 1.2 million casualties caused by gas attacks. Gas was unlike most other weapons of the period because it was possible to develop effective countermeasures, such as gas masks. In the later stages of the war, as the use of gas increased, its overall effectiveness diminished. The widespread use of these agents of chemical warfare, and wartime advances in the composition of high explosives, gave rise to an occasionally expressed view of World War I as "the chemist's war" and also the era where "weapons of mass destruction" were created.
Document 15: Pueblo Chemical Depot: The Pueblo Chemical Depot is a chemical weapons storage site located in Pueblo County, Colorado, United States. The Pueblo Chemical Depot is one of the last two sites in the United States with chemical munitions and chemical material. The Pueblo Chemical Agent Destruction Pilot Plant (PCAPP) which is under the Assembled Chemical Weapons Alternatives (ACWA) program will destroy its stockpile of 155-mm and 105-mm artillery shells and 4.2-in. mortars, all of which contain a form of the chemical agent mustard.
