How can people be exposed to nerve agents?
Sarin, soman and tabun are about the consistency of water and can form vapor that floats in the air. These agents generally enter the body through breathing the vapor. VX is different because it has the consistency of motor oil and does not easily form a vapor. VX harms people when the liquid enters the body through the skin. If a nerve agent were used in an attack, people coming into contact with either the liquid or the vapor could be harmed. Terrorists could release nerve agents into a crowded area. Nerve agents are more harmful if released in enclosed areas compared to outdoors. How can people recognize that they are sick from nerve agents? If you see several people suddenly become ill, you should suspect a nerve agent release. Symptoms of exposure to nerve agent vapor may include: eye burning, tearing, pain and dim vision; runny nose, cough and difficulty breathing; headache, lightheadedness, confusion and weakness; sweating; stomach aches and diarrhea; and, muscle twitching.
