History

Simple chemical weapons were used sporadically throughout antiquity and into the Industrial age. It was not until the 19th century that the modern conception of chemical warfare emerged, as various scientists and nations proposed the use of asphyxiating or poisonous gasses. So alarmed were nations that multiple international treaties, discussed below, were passed banning chemical weapons. This however did not prevent the extensive use of chemical weapons in World War I. The development of

. Though largely ineffective over the long run, it decidedly changed the nature of the war. In many cases the gasses used did not kill, but instead horribly maimed, injured, or disfigured casualties. Some 1.3 million gas casualties were recorded, which may have included up to 260,000 civilian casualties. The interwar years saw occasional use of chemical weapons, mainly to put down rebellions."Chemical Weapons" in ''Historical Dictionary of Ethiopia'', 2d ed. (eds. David H. Shinn & Thomas P. Ofcansky: Scarecrow Press, 2013). In Nazi Germany, much research went into developing new chemical weapons, such as potent

s. However, chemical weapons saw little battlefield use in World War II. Both sides were prepared to use such weapons, but the Allied powers never did, and the Axis used them only very sparingly. The reason for the lack of use by the Nazis, despite the considerable efforts that had gone into developing new varieties, might have been a lack of technical ability or fears that the Allies would retaliate with their own chemical weapons. Those fears were not unfounded: the Allies made comprehensive plans for defensive and retaliatory use of chemical weapons, and stockpiled large quantities.Paxman and Harris

Manner and form

There are three basic configurations in which these agents are stored. The first are self-contained munitions like projectiles, cartridges, mines, and rockets; these can contain propellant and/or explosive components. The next form are aircraft-delivered munitions. Together they constitute the two forms that have been weaponized and are ready for their intended use. The U.S. stockpile consisted of 39% of these weapon ready munitions. The final of the three forms are raw agent housed in one-ton containers. The remaining 61% of the stockpile was in this form. Whereas these chemicals exist in liquid form at normal room temperature, the sulfur mustards H and HD freeze in temperatures below . Mixing lewisite with distilled mustard lowers the freezing point to . Higher temperatures are a bigger concern because the possibility of an explosion increases as the temperatures rise. A fire at one of these facilities would endanger the surrounding community as well as the personnel at the installations. Perhaps more so for the community having much less access to protective equipment and specialized training. The

In 1982, that study culminated in the selection of incineration technology, which is now incorporated into what is known as the ''baseline'' system. Construction of the

To address growing public concern over incineration, Congress, in 1992, directed the Army to evaluate alternative disposal approaches that might be "significantly safer", more cost effective, and which could be completed within the established time frame. The Army was directed to report to Congress on potential alternative technologies by the end of 1993, and to include in that report: "any recommendations that the

The Chemical Materials Agency (CMA) releases regular updates to the public regarding the status of the disposal program. By October 2010, the program had reached 80% destruction status.


Lethality

Chemical weapons are said to "make deliberate use of the toxic properties of chemical substances to inflict death". At the start of World War II it was widely reported in newspapers that "entire regions of Europe" would be turned into "lifeless wastelands". However, chemical weapons were not used to the extent predicted by the press. An unintended chemical weapon release occurred at the port of

attack on the evening of December 2, 1943, damaged U.S. vessels in the harbour and the resultant release from their hulls of mustard gas inflicted a total of 628 casualties. The U.S. Government was highly criticized for exposing American service members to chemical agents while testing the effects of exposure. These tests were often performed without the consent or prior knowledge of the soldiers affected. Australian service personnel were also exposed as a result of the "Brook Island trials" carried out by the British Government to determine the likely consequences of chemical warfare in tropical conditions; little was known of such possibilities at that time. Some chemical agents are designed to produce mind-altering changes; rendering the victim unable to perform their assigned mission. These are classified as incapacitating agents, and lethality is not a factor of their effectiveness.


Unitary versus binary weapons

Binary munitions contain two, unmixed and isolated chemicals that do not react to produce lethal effects until mixed. This usually happens just prior to battlefield use. In contrast, unitary weapons are lethal chemical munitions that produce a toxic result in their existing state. The majority of the chemical weapon stockpile is unitary and most of it is stored in one-ton bulk containers.
