If breathing is difficult, administer oxygen. Don respiratory protective mask and remove contaminated clothing. Rinse well with water to remove excess decontaminant. Mark I, only if local sweating and muscular twitching symptoms are observed. Do not induce vomiting.
First symptoms are likely to be gastrointestinal.
Relatively stable at room temperature. Negligible on brass, steel, aluminum. The large scale decon procedure, which uses both HTH and NaOH, destroys VX by oxidation and hydrolysis. At pH 12, the EA2192 in the large scale product has a half-life of about 14 days. This holding period is sufficient to reduce the toxicity of the product below that of a Class B poison.
