Soman skin contact

Soman (pinacolyl methylphosphonofluoridate), called GD in the United States, is a moderately volatile substance that can be taken by inhalation or skin contact. 

Soman (GD) Pinoacolyl methylphosphonogluoridate fastest-killing nerve gas, produced in 1944 for the first time at I.G. Farben, Germany kills both through inhalation and skin contact. 

Following release of soman into the air, people can be exposed through skin contact, eye contact, or inhalation (breathing in the. soman). 

Soman is liquid at room temperature and evaporates quickly once the container is opened. It may be thickened into an oily consistency that does not evaporate but wiU be absorbed through direct skin contact. 

Inhalation of all nerve agents takes between seconds and minutes to cause an effect with maximal effect after exposure ends. Skin contact may delay action for a few minutes to a few hours. Soman is more lethal than sarin and tabun. 

Non-persistent agents, such as sarin, soman and tabun, disperse rapidly after release and present an immediate short duration inhalational hazard but may be made persistent by a thickening agent , such as ethyl methacrylate. In contrast, persistent agents, such as VX, continue to be a contact hazard and may be absorbed through the skin or can vaporize over a prolonged period to produce an inhalation hazard.
