 FAQ'S about Chemical Nerve Agents

Frequently Asked Questions about Chemical Nerve Agents
The effects of nerve agents appear almost immediately. In a large group of exposed people, these effects will range from relatively minor effects to very severe effects that may lead to death.
Sarin(GB)
Tabun(GA)
Soman(GD)
VX

 Sarin (GB)

Sarin is classified as a nerve agent that disrupts the transmission of nerve impulses in the body. It is a colorless, odorless liquid that mixes readily in water. Sarin can be ingested, inhaled, or absorbed through the skin.

What are the health effects of sarin exposure?
How is exposure to sarin diagnosed?
How can sarin exposure be treated?

What are the health effects of sarin exposure?

Depending on the dose, onset of clinical manifestations can vary from a few minutes to 1 hour, although most occur within minutes. Signs and symptoms include visual disturbance, runny nose, chest tightness, nausea, vomiting, convulsions, and death.

How is exposure to sarin diagnosed?

Exposure to sarin is diagnosed by recognizing the signs and symptoms of exposure to nerve agents (visual disturbance, runny nose, chest tightness, nausea, vomiting, and convulsions).

How can sarin exposure be treated?

Treatment includes atropine, pralidoxime chloride, and diazepam. Using appropriate personal protective equipment, remove, bag, and seal contaminated clothing. Decontaminate skin by washing it twice with large amounts of soap and water. Secondary exposure can occur from contact with contaminated clothing; it can also occur when sarin evaporates from contaminated clothing. To protect health care workers and others exposed to a contaminated victim from secondary contamination, remove, bag, and seal the victim’s clothing, and wash the victim’s skin twice with large amounts of soap and water. For more information about sarin, visit the CDC Web site www.bt.cdc.gov.

 Tabun (GA)

Tabun is classified as a nerve agent that interrupts the transmission of nerve impulses in the body. It is a colorless-to-brownish liquid. Under average weather conditions, tabun can persist for 1-2 days; it is primarily released as an aerosol or vapor.

What are the health effects of tabun?
How is exposure to tabun diagnosed?
How can exposure to tabun be treated?

What are the health effects of tabun?

Clinical signs and symptoms include visual disturbance, runny nose, chest tightness, nausea, vomiting, convulsions, and death.

How is exposure to tabun diagnosed?

Tabun is detected on the basis of the history of exposure, clinical signs and symptoms, and confirmatory laboratory tests. The signs and symptoms of tabun exposure include visual disturbance, runny nose, chest tightness, nausea, vomiting, and convulsions.

How can exposure to tabun be treated?

Treatment includes atropine, pralidoxime chloride, and diazepam. Using appropriate personal protective equipment, remove, bag, and seal contaminated clothing. Decontaminate skin by washing it with large amounts of soap and water. Secondary exposure can occur from contact with contaminated clothing; it can also occur when tabun evaporates from contaminated clothing. To protect health care workers and others exposed to a contaminated victim from secondary contamination, remove, bag, and seal the victim’s clothing, and wash the victim’s skin with large amounts of soap and water. For more information on tabun, visit the CDC Web site www.bt.cdc.gov.

 Soman (GD)

Soman is classified as a nerve agent that disrupts the transmission of nerve impulses in the body. It is a colorless and tasteless liquid that mixes readily with water. Released soman evaporates rapidly, dissipates, and eventually breaks down in the environment.

What are the symptoms of soman exposure?
How is soman exposure diagnosed?
How is exposure to soman treated?

What are the symptoms of soman exposure?

Clinical manifestations include visual disturbance, runny nose, chest tightness, nausea, vomiting, convulsions, and death

How is soman exposure diagnosed?

Diagnosis is based on history of exposure, clinical signs and symptoms, and confirmatory laboratory tests. Signs and symptoms of soman exposure include visual disturbance, runny nose, chest tightness, nausea, vomiting, and convulsions.

How is exposure to soman treated?

Treatment consists of decontamination; drugs such as atropine, pralidoxime chloride, and diazepam; ventilation to support respiratory function; and supportive care. Contaminated clothing must be removed, bagged, and sealed. Decontaminate skin by washing it with large amounts of soap and water. Secondary exposure can occur from contact with contaminated clothing; it can also occur when soman evaporates from contaminated clothing. To protect health care workers and others exposed to a contaminated victim from secondary contamination, remove, bag, and seal the victim’s clothing, and wash the victim’s skin with large amounts of soap and water. For more information on soman, visit the CDC Web site www.bt.cdc.gov.

 VX

VX is a nerve agent that disrupts the transmission of nerve impulses in the body. It is an amber-colored, oily liquid that will remain in the environment (persistent) until it has been properly cleaned through decontamination methods. VX can enter the body through ingestion, inhalation, or through the eyes or skin.

What are the health effects of VX exposure?
How is exposure to VX diagnosed?
How is exposure to VX treated?

What are the health effects of VX exposure?

Health effects include constricted pupils, visual disturbance, runny nose, chest tightness, nausea, vomiting, convulsions, and death.

How is exposure to VX diagnosed?

Diagnosis is based on history of exposure, clinical signs and symptoms, and confirmatory laboratory tests. Signs and symptoms of VX exposure include visual disturbance, runny nose, chest tightness, nausea, vomiting, and convulsions.

How is exposure to VX treated?

Treatment includes atropine, pralidoxime chloride, and diazepam; ventilation to support respiratory function; and supportive care. Using appropriate personal protective equipment, remove, bag, and seal contaminated clothing. Decontaminate skin by washing it with large amounts of soap and water. Because of VX’s persistent characteristics, take care to prevent secondary cases from contaminated clothing, ground, vegetation, or equipment.
