Comments |
Soman a colorless liquid with a fruity or oil of camphor odor and a vapor pressure of 0.4 mm Hg at 77 degrees F. It is relatively persistent in the soil. [Jane, p. 85-6] The LD50 on skin is 50 mg. The LCt50 is 70 mg-min/m3. Soman undergoes 'aging' in about two minutes. Treatment of casualties is more difficult than for other nerve agents that take longer to age. After two minutes, the usefulness of oximes is reduced. [USAMRICD, p. 107, 110] "As little as one drop of VX on the skin can be fatal and 1 to 10 mL of GA, GB, or GD can be fatal."
