Here’s some background information about sarin, a man-made nerve agent developed for chemical warfare.

Sarin is a liquid that is clear, colorless, tasteless and odorless.

Sarin is an extremely volatile nerve agent because of its ability to change from liquid to gas.

If it evaporates into a gas, it can spread into the environment.

Sarin’s designation by NATO is GB.

People are exposed to sarin through skin contact, eye contact or by breathing it in. Sarin can also be mixed with water or food.

Sarin dissipates quickly, presenting an immediate but short-lived threat.

Sarin’s main ingredient is methyl phosphonyl difluoride.

Mild or moderately exposed people usually recover completely. Severely exposed people are not likely to survive.

Symptoms of mild to moderate exposure include: (from the CDC)
Runny nose
Watery eyes
Small, pinpoint pupils
Eye pain
Blurred vision
Drooling and excessive sweating
Chest tightness
Rapid breathing
Increased urination
Nausea, vomiting, and/or abdominal pain
Slow or fast heart rate

Symptoms of severe exposure include:
Loss of Consciousness
Respiratory failure possibly leading to death

Leave the area of contamination as quickly as possible. Seek fresh air if exposure occurs indoors. If exposure is outdoors, head to higher ground as sarin is heavier than air and sinks.

Remove contaminated clothing, flush eyes with water, and wash skin with soap and water.

If ingested, do not induce vomiting or flush with fluids.

Medical care should be sought immediately. Antidotes are available in many hospitals.

1938Sarin is developed in Germany as a pesticide.

April-May 1967 – The US military secretly tests sarin in the Upper Waiakea Forest Reserve on the island of Hawaii. The testers detonate sarin-filled 155mm artillery shells to study how the nerve agent disperses in a tropical jungle. The Pentagon confirms the “Red Oak” program in November 2002.

March 1988 On “Bloody Friday,” the Iraqi air force attacks the northern Iraq town of Halabja with poison gases that were thought to include sarin, VX and other deadly compounds. Reports indicate that 5,000 people die in the attack. Countless others suffer eyesight loss, respiratory ailments and cancers.

June 27, 1994 In Japan, seven people die and more than 500 are hospitalized when the Aum Supreme Truth (or Aum Shinri Kyo) cult releases sarin from a truck by driving slowly around an apartment complex in Matsumoto, Nagano Prefecture. Another victim dies in 2008.

March 20, 1995 – The Aum Supreme Truth cult, now known as Aleph, places plastic bags of sarin on trains that converge in the Tokyo government district during rush hour. Thirteen people die and more than 5,000 become ill.

May 17, 2004 A coalition convoy in Baghdad finds sarin gas in an artillery round that had been rigged as an improvised explosive device. The IED detonates as officials attempt to defuse it. Two members of the explosive ordinance team suffer minor exposure.

June 23, 2006 The US Army releases a report to Congress stating that allied forces had recovered approximately 500 weapons munitions containing degraded mustard or sarin gas since the start of the Iraq War in 2003. The weapons had been produced before the 1991 Gulf War. However, according to October 2014 reporting by the New York Times, even at the time of the report’s publication, which was never updated, the information was “outdated” and “understated.”

June 15, 2012 Katsuya Takahashi, 54, the last fugitive suspect in the 1995 sarin attacks on the Tokyo subway is captured by Japanese police, ending a 17-year manhunt.

April 25, 2013 US Defense Secretary Chuck Hagel announces that Syria has used sarin on a small scale, killing 150 people in the country.

August 21, 2013 – A new alleged chemical weapons attack kills more than 1,000 people in the Syrian countryside outside its capital, Damascus. Hundreds of those killed are children.

September 1, 2013 – US Secretary of State John Kerry announces that samples of blood and hair taken from eastern Damascus have “tested positive for signatures of sarin.”

September 16, 2013 – UN weapons inspectors return “overwhelming and indisputable” evidence of the use of sarin in Syria, UN Secretary-General Ban Ki-moon says, calling the findings “beyond doubt and beyond the pale.”

January 4, 2016 – The UN releases a report that indicates Syrians may have been exposed to a sarin-type gas in 11 instances. The UN bases its report on a publication by the Organization for the Prohibition of Chemical Weapons (OPCW). Source of the gas and those responsible for its use are being investigated.

April 4, 2017 – An airstrike on a rebel-held town in northwestern Syria leaves 89 civilians dead, including children, from a suspected chemical attack, using sarin gas. The US, Turkey and other Western states blame the regime of Syrian President Bashar al-Assad who vehemently denies the accusation. The following week, UK scientists claim to have evidence that sarin gas, or a similar substance, was used based on samples tested from victims. Investigations continue to confirm the gas used and those responsible.

April 26, 2017 – French Foreign Minister Jean-Marc Ayrault announces that samples taken from the attack on the rebel-held town of Khan Sheikhoun matched those from a previous incident, and that the evidence provides proof that the Syrian regime is responsible for carrying out the attack on April 4.

July 2018 – Cult leader Shoko Asahara, and twelve other members of the Aum Shinrikyo cult are executed for their roles in the 1995 Tokyo sarin attack which left more than a dozen people dead and thousands injured.
