What gas kills you instantly?

Do astronauts breathe pure oxygen?
When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside spacesuits, astronauts have the oxygen they need to breathe. … Once in their suits, astronauts breathe pure oxygen for a few hours. Breathing only oxygen gets rid of all the nitrogen in an astronaut’s body.
How do you die from sarin gas?

Carbon monoxide is both invisible and odorless, so you may breathe it in large quantities without even knowing it. This can cause permanent brain damage and even death.
Which gas can cause death?
When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can lead to serious tissue damage, or even death. Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel.
