Yes. This method is perceived to be more inexpensive by the public, but actually costs twice as much.
Relatively few shelters use this method as it takes a significant amount of time and supplies and is a public relations night mare - just picture a heading comparing a shelter euthanizing animals with some of the atrocities of the Holocaust. Most shelters use an injectable euthanasia method as it is reliable, easily administered and relatively inexpensive.
No. High amounts of gases commonly used as anasthetics are used to humanely kill dogs and other animals.
No, the gas used in veterinary medicine for euthanasia is carbon dioxide. However, because this method is technically difficult and can cause some anxiety in larger dogs, it is not used to euthanize dogs.
Hydrogen cyanide or Zyklon B as it was called.
Josef Mengele and the Nazis in the Gas Chambers
There is one company in the Czech Republic that still makes Zyklon B, though they market it under another name. Its marketed as an insect killer, which was the purpose for which it was originally developed. I'd say that what gets used in animal shelters varies from shelter to shelter. I know of one near my home that used to use engine exhaust. I'd imagine quite a few use cyanide crystals and hydrochloric acid to create cyanide gas, as is done in gas chambers on death row in penitentiaries.
We all may hope NOT as free ionic compound, because cyanide is very, very toxic; e.g. used in the Holocaust German gas chambers as Zyclon(R)B
The poison used to kill possums has arsenic in it. It can also contain cyanide, ethylene glycol, and several other dangerous chemicals that are used to kill the animal.
cyanide tablets turned into gas
Zyklon B was an extremely poisonous gas that was used during World War ll. It was used in the gas chambers in the concentration camps to kill the Jews instantly.Zyklon B is a transport system for hydrogen cyanide, its active ingredient. H-cyanide is a cytotoxin that interferes with cellular respiration, which can generate neurotoxic effects.
The cyanide based pesticide which was used by the Nazis to kill Jews was called Zyklon B.
One of the methods were gas chambers.
A painless injection, that puts the animal "to sleep" as they say. Injection of an OD with sodium pentobarbital is preferred. However several other methods less humane are used including gas chambers.
