Exposure is lethal even at very low concentrations, where death can occur within one-to-ten minutes after direct inhalation of a lethal dose, due to suffocation from lung muscle paralysis, unless antidotes are quickly administered.
If the exposure was great enough, that can progress to convulsions, paralysis, and death within 1 to 10 minutes. If the exposure was not enough to kill them, though, the person should recover pretty quickly and completely.
One may also ask, what is the antidote for sarin gas? Atropine .
Sarin gas gets in the way of this enzyme and disrupts the nervous system. A person can also become paralyzed, experience convulsions, start vomiting and lose control of their bowels, tear ducts, virtually any function the nervous system touches.
Nerve agents are highly toxic chemicals called "organophosphates" that poison the nervous system and disrupt bodily functions which are vital to an individual's survival. They were originally produced in a search for insecticides, but because of their toxicity, they were evaluated for military use.
Below is a list of answers to questions that have a similarity, or relationship to, the answers on "How quickly does sarin gas kill?". This list is displayed so that you can easily and quickly access the available answers, without having to search first.
Like other nerve agents, sarin targets an enzyme within the body's neuromuscular junctions, where nerves meet muscles. Usually, this enzyme deactivates the nerve-signaling molecule acetylcholine. This can lead acetylcholine to build up in the muscles, cause excessive twitching and then result in paralysis, said Dr.

NamesNIOSH (US health exposure limits):IDLH (Immediate danger) 0.1 mg/m3
Unlike chemical nerve agents such as organophosphates or sarin gas, which immediately incapacitate victims, mustard gas victims typically don't exhibit symptoms of poisoning until 12 to 24 hours after exposure. However, higher concentrations of the gas can cause symptoms to develop within one to two hours.
Organophosphate pesticides such as parathion are in the same chemical class as nerve agents. Although these pesticides are much less toxic, their effects and medical treatments are the same as for military-grade nerve agents. Bacillus anthracis, the bacterium that causes anthrax, is capable of causing mass casualties.
Dose toxicity Humans can smell chlorine gas at ranges from 0.1–0.3 ppm. At 5–15 ppm, there is moderate mucous membrane irritation. At 30 ppm and beyond, there is immediate chest pain, shortness of breath, and cough. At approximately 40–60 ppm, a toxic pneumonitis and/or acute pulmonary edema can develop.
The estimated respiratory lethal dose is 1500 mg. min/m3. On bare skin, 4 g–5 g of liquid mustard gas may constitute a lethal percutaneous dosage, while droplets of a few milligrams may cause incapacitation and significant skin damage and burns.
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.
A third category of chemical weapon is comparably savage—the nerve-gas agents. The fourth group of chemical agents is the so-called blood group—cyanide products delivered various ways that enter the bloodstream and cause lethal cyanide poisoning.
Sarin is a human-made chemical warfare agent classified as a nerve agent. Sarin is a clear, colorless, and tasteless liquid that has no odor in its pure form. However, sarin can evaporate into a vapor (gas) and spread into the environment.
Nerve gas. Nerve gas, Weapon of chemical warfare that affects the transmission of nerve impulses through the nervous system. A single droplet of VX or Sarin, if inhaled or in contact with the skin, can be absorbed into the bloodstream and paralyze the nervous system, leading to respiratory failure and immediate death.
It alleged that US aircraft, in an unprecedented reversal of policy and breach of international treaties, had used sarin nerve gas ("GB" in US/NATO nomenclature) against North Vietnamese ground troops who were attacking the landing zones during the extraction of the forces.
The bitter-almond smell of the hydrogen cyanide in Zyklon B permeated the gas chambers at the Nazi death camps in the 1940s. Another nerve gas called soman smells like Vicks VapoRub or rotting fruit.
VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research.
