HCN.

This is coolbert:

Poison powder that can become poison gas. Blood agent to be exact. Poison gas of extreme lethality.

In the aftermath of that catastrophic explosion in China danger still existing.

"All about sodium cyanide, the extremely toxic chemical found in vast quantities at the Tianjin explosion site"

"Officials investigating a huge explosion at a warehouse in Tianjin in China have discovered a store of 700 tonnes of sodium cyanide—more than 70 times the legal limit allowed. Cyanide has a particularly unpleasant reputation and finding it at a major disaster site is far from welcome. However, if officials act fast they should be able to limit its damaging effects."

This image shows the ground zero [?] of the "Tianjin explosion site". Click on image to see an enlarged view. Somewhere in the rubble is the stockpile of sodium cyanide that has been "cooked". and heated. Rain falling on the debris will release hydrogen cyanide gas. Blood agent!!

Sodium cyanide a poison in powder form as used in a variety of industrial processes and having a lethality. That large store of the powder now having been "'cooked' and heated" by the detonation now susceptible to an out-gassing of hydrogen cyanide [HCN]. HCN a BLOOD AGENT as used by the military during chemical warfare.

I WOULD LIKE TO BELIEVE AMERICAN HOMELAND SECURITY IS PAYING PROPER ATTENTION TO THIS INCIDENT. ATTEMPTING TO DETERMINE ALL SUCH SIMILAR INDUSTRIES IN THE UNITED STATES THAT MAINTAIN CHEMICAL STORES OF SODIUM CYANIDE AND ADVISING USERS ON THE PROPER HANDLING, STORAGE AND SAFEGUARDING!
