• Beschreibung

  Mustard gas/sulphur mustard is an organic chemical substance synthesised by treating sulphur dichloride with ethylene. Mustard gas is a chemical substance closely related to chemical warfare class agents. It is a cytotoxic and vesicant chemical substance, and exposures are known to cause blisters on the exposed skin. Pure mustard gas/sulphur mustards are colourless, viscous liquids at room temperature. However, when used in impure form, such as warfare agents, they appear as yellow brown in colour. As the name indicates, mustard gas has an odour resembling the garlic, horseradish, or mustard plants. Mustard gas is the common name given to 1,1-thiobis(2-chloroethane), a chemical warfare agent that is believed to have first been used near Ypres in Flanders on 12 July 1917. Mustard gas is a thick liquid at ambient temperature. It is heavier than water as a liquid and heavier than air as a vapour. It does not occur naturally in the environment. Pure liquid mustard gas is colourless and odourless. It is stable, combustible, and incompatible with strong oxidising agents. Mustard gas on mixing with other chemical substances appears brown in colour and gives off a garlic-like smell. When heated, it decomposes and emits highly toxic, corrosive fumes and fumes of oxides of sulphur and chlorine-containing compounds. It is soluble in fats and oils, gasoline, kerosene, acetone, carbon tetrachloride, alcohol, tetrachloroethane, ethylbenzoate, and ether, and solubility in water is negligible. It is miscible with the OP nerve agents. During earlier years, mustard gas was in use as an important chemical warfare agent. In fact, it was used in large amounts during World Wars I and II. Mustard gas was first used by the German army in 1917. It was one of the most lethal of all the poisonous chemicals used during the war. It was reportedly used in the Iran–Iraq war in 1980–1988. It is not presently used in the United States, except for research purposes.

• Chemische Eigenschaften

  Mustard gas, a chlorinated sulfur compound(s), is an oily, yellow to black liquid (clear when pure). It has a sweet, burnt garlic or horseradish-like odor. The odor threshold for HD is 0.0006 milligram per cubic meter.

• Verwenden

  Sulfur mustard (SM) is a chemical warfare agent belonging to the blister agent/vesicant class. It is a cytotoxic and alkylating compound similar to other types of vesicants or blister agents such as nitrogen mustard, lewisite, and phosgene oxide. SM was used on a large scale during World War I and in the Iraq– Iran conflict in 1983–1988. It was also used by Italian troops in Ethiopia (1935–1936) and by Egyptian forces in Yemen (1963–1967). Most of the Iranian patients are still suffering from the delayed toxic effects and complications of SM poisoning.

• Verwenden

  As a vesicant in chemical warfare. Although US stockpiles were thought to exist only through the early 1970s, several other countries currently maintain large stockpiles that present an imminent danger from accidental or intentional exposure.1 Also used in small quantities as a model compound in biological studies on alkylating agents.

• Verwenden

  Formerly in chemical warfare. In biological studies of alkylating agents.

• Definition

  ChEBI: An ethyl sulfide that is diethyl sulfide in which a hydrogen from each of the terminal methyl groups is replaced by a chlorine. It is a powerful vesicant regulated under the Chemical Weapons Convention.

• Allgemeine Beschreibung

  Mustard gas is a clear amber colored oily liquid with a faint odor of mustard/garlic. Mustard gas is not readily combustible. Its vapors are heavier than air, are very toxic, and can be absorbed through the skin. The effects from exposure to the material include blindness which may be delayed. Prolonged exposure of the container to fire or intense heat may cause Mustard gas to violently rupture and rocket. Mustard gas is also known as dichlorodiethyl sulfide.

• mögliche Exposition

  Mustard gas is used as an alkylating agent. It has also been used as a chemical warfare agent, causing delayed casualties. It is a vesicant and blister agent in chemical warfare (especially during World War I, military designation H or HD). Mustard gas is used as a model compound in biological studies. Mustard gas has been tested as an antineoplastic agent, but its clinical use as a tumor inhibitor has been minimal.

• Erste Hilfe

  There is no antidote for sulfur mustard toxicity.If this chemical gets into the eyes instantly flush with water.A delay of seconds can cause permanent damage.Inhalation: Remove from the source immediately. If breathing has stopped, give artificial respiration. If breathing isdifficult, administer oxygen. Seek medical attention immediately. Eye contact: Speed in decontaminating the eyes isabsolutely essential. Remove person from the liquid source;flush the eyes immediately with water by tilting the head tothe side, pulling the eyelids apart with the fingers, and pouring water slowly into the eyes. Do not cover eyes with bandages but, if necessary, protect eyes by means of dark oropaque goggles. Transfer the patient to a medical facilityimmediately. Ingestion: Do not induce vomiting. Give victim milk to drink. Seek medical attention immediately. Skincontact: Don respiratory protective mask and gloves;remove victim from agent source immediately. Flush skinand clothes with solution of sodium hypochlorite or liquidhousehold bleach (see decontamination procedure below)within 1 min. Cut and remove contaminated clothing, flushcontaminated skin area again with sodium hypochloritesolution, then wash contaminated skin area with soap andwater.

• Toxicity evaluation

  Although SM reacts with RNA, proteins, and phospholipids, the consensus view is that a DNA alkylate plays an important role in delayed toxic effects. This DNA alkylation and crosslinking in rapidly dividing cells such as basal keratinocytes, mucosal epithelium, and bone marrow precursor cells leads to cellular death and inflammatory reactions. At higher levels of cellular exposure, however, mechanisms other than DNA crosslinking that produce more rapid cell death may become important. The acute damage to the cornea, mucous membranes, and skin seen after SM exposure is probably generated by one or both of these two mechanisms: (1) depletion of nicotinamide adenine dinucleotide (NAD); (2) rapid inactivation of sulfhydryl-containing proteins and peptides, such as glutathione.

• Inkompatibilitäten

  Sulfur mustard is stable at ambient temperatures. Reacts with oxidizers (vigorous), strong acids; acid fumes; strong alkalies; oxygen; water, steam, and other forms of moisture. On contact with acid or acid fumes, it emits highly toxic fumes of oxides of sulfur and chlorine. Rapidly corrosive to brass @ 65℃. Will corrode steel at a rate of 0.0001 in/month @ 65℃. HD reacts with water; will hydrolyze; forming HCI and thiodiglycol. When heated to decomposition (between 149℃ to 177℃), it emits gaseous hydrogen chloride and oxides of sulfur and chlorine. Contact with metals may evolve flammable hydrogen gas.

• Waste disposal

  Principles and methods for destruction of chemical weapons: “Destruction of chemical weapons” means a process by which chemicals are converted in an essentially irreversible way to a form unsuitable for production of chemical weapons, and which in an irreversible manner renders munitions and other devices unusable as such. Each nation shall determine how it shall destroy chemical weapons, except that the following processes may not be used: dumping in any body of water, land burial or open-pit burning. It shall destroy chemical weapons only at specifically designated and appropriately designed and equipped facilities. Each nation shall ensure that its chemical weapons destruction facilities are constructed and operated in a manner to ensure the destruction of the chemical weapons; and that the destruction process can be verified under the provisions of this Convention . All decontaminated material should be collected, contained and chemically decontaminated or thermally decomposed in an EPA approved incinerator, which will filter or scrub toxic by-products from effluent air before discharge to the atmosphere. Any contaminated protective clothing should be decontaminated using calcium hypochlorite (HTH) or bleach and analyzed to assure it is free of detectable contamination (3X) level. Contaminated clothes and personal belongings should be placed in a sealed double bag and subsequently placed inside properly labeled drums and held for shipment back to the DA issue point. Decontamination of waste or excess material shall be accomplished in accordance with the procedures outlined above with the following exceptions: (a) HD on laboratory glassware may be oxidized by its vigorous reaction with concentrated nitric acid. (b) Open pit burning or burying of HD or items containing or contaminated with HD in any quantity is prohibited. Note: Several states define decontaminated surety material as a RCRA Hazardous Waste.
