When humans breathe in an asphyxiant gas, such as pure nitrogen, helium, neon, argon, methane, or any other physiologically inert gas, they exhale carbon dioxide without re-supplying oxygen. Physiologically inert gases (those that have no toxic effect, but merely dilute oxygen) are generally free of odor and taste. Accordingly, the human subject detects little abnormal sensation as the oxygen level falls. This leads to asphyxiation (death from lack of oxygen) without the painful an… Webb3.3.140.15 Definitions, Simple Asphyxiant Gas A gas that does not provide sufficient oxygen to support life and that has none of the other physical or health hazards ...
