Arsine-SA

Vapor pressure Volatility 11,100 mmHg at 20°C. This high vapor pressure means that SA is difficult to liquefy and to store. 30,900,000 mg-min/m3 at 20°C. This by far the highest volatility found among the compounds considered for tactical use as chemical agents. This fact, coupled with a relatively low latent heat of vaporization, qualifies SA as the most rapidly dispersing chemical agent. 

Reactivity Hydrolysis products Arsenic acids and a hydride containing fewer hydrogen atoms than SA itself.

but reaches an equilibrium condition quickly. (Under certain conditions SA forms a solid product with water that decomposes at 30°C.) 

Not stable in uncoated containers. Metals catalyze decomposition of SA. Reacts slowly with copper, brass, and nickel. Contact with other metals may also decompose it.

Blood agents Also known as cyanogens, they include arsine (SA), cyanogen chloride (CK), and hydrogen chloride (AC), and are transported in the bloodstream through the body. Blood agents do not typically affect the blood but may interrupt the production of blood components and cause toxic effect at the cellular level.

Blood agents, which enter the body primarily through the respiratory tract, prevent the normal utilization of oxygen by blood cells. Included are hydrogen cyanide (AC), cyanogen chloride (CK), and arsine (SA). Figure 2.5 shows blood agent structures, and Table 2.5 shows properties.
