A chemical warfare nerve agent. A colorless, odorless liquid. Almost no odor in pure state.

• Water-Reactive

Hydrolyzed by water to form hydrogen fluoride and the nontoxic phosphonic acid derivative. It is rapidly hydrolyzed by dilute aqueous sodium hydroxide [Merck 11th ed. 1989].

For information on chemical warfare nerve agents see the ERG Criminal or Terrorist Use of CBR Agents. (ERG, 2024)

Non-flammable. Acidic conditions produce hydrogen fluoride; alkaline conditions produce isopropyl alcohol and polymers. When heated to decomposition or reacted with steam, it emits very toxic fumes of fluorides and oxides of phosphorus. Slightly corrosive to steel. Hydrolyzed by water. (EPA, 1998)

Extremely toxic; lethal dose in humans may be as low as 0.01 mg/kg. Extremely active cholinesterase inhibitor. Toxic effects similar to, but more severe than those of parathion. Death within 15 minutes after fatal dose is absorbed. (EPA, 1998)

For initial isolation and protective action distances for chemical warfare nerve agents see the Chemical Warfare Agents table in the ERG Criminal or Terrorist Use of CBR Agents. (ERG, 2024)

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Protective clothing and respiratory protection.

Extinguish with foam, carbon dioxide, and dry chemical (EPA, 1998)

For information on chemical warfare nerve agents see the ERG Criminal or Terrorist Use of CBR Agents. (ERG, 2024)

Rapidly hydrolyzed by dilute aqueous sodium hydroxide or sodium carbonate forming relatively non-toxic products. Water alone removes the fluorine atom producing a non-toxic acid. Decontaminants include bleach slurry, dilute alkali, hot soapy water, steam and ammonia. (EPA, 1998)

For information on chemical warfare nerve agents see the ERG Criminal or Terrorist Use of CBR Agents. (ERG, 2024)

For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

Note: Sarin is an EXTREMELY ACTIVE cholinesterase inhibitor. Warning: Death may occur within 1 to 10 minutes of inhalation exposure to a minute amount of sarin. Immediate decontamination of the smallest drop is essential. Effects may be delayed with dermal exposure. Extreme caution is advised.

Signs and Symptoms of Sarin Exposure: The first indication of exposure to sarin may be a reaction at the point of contact: localized sweating, muscular twitching, and pinpoint eye pupils. Rhinorrhea (running nose), tightness of the chest with shortness of breath, and dimness of vision may be noted. In more severe exposure, headache, cramps, nausea, vomiting, involuntary defecation and urination, twitching, jerking, staggering, convulsions, drowsiness, coma, and respiratory arrest may be seen.

Emergency Life-Support Procedures: Acute exposure to sarin may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to sarin.
2. RUSH to a health care facility!
3. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. DO NOT perform mouth-to-mouth resuscitation when facial contamination exists; use forced-oxygen mask. If breathing is labored, administer oxygen or other respiratory support.
4. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.

Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to sarin.
2. RUSH to a health care facility!
3. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. DO NOT perform mouth-to-mouth resuscitation when facial contamination exists; use forced-oxygen mask.
4. Remove and isolate contaminated clothing as soon as possible.
5. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
6. Wash exposed skin areas thoroughly with commercial household liquid bleach and then flush with water. Avoid contacting the eyes or mouth with bleach.
7. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.

Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. DO NOT perform mouth-to-mouth resuscitation when facial contamination exists; use forced-oxygen mask. If breathing is labored, administer oxygen or other respiratory support.
2. RUSH to a health care facility!
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. DO NOT induce vomiting or attempt to neutralize.
5. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
6. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults. (EPA, 1998)
