Webbother asphyxiant gas can accumulate and develop localised oxygen depletion volumes. Gases that are lighter than air will have some mixing through buoyant flow. Heavier than air gases do tend to accumulate at floor level. However, there is a myth that neutrally buoyant gases, like nitrogen, (having a similar density to air) mix readily with air.

WebbNitrogen, compressed gas is a simple asphyxiant. Release in an enclosed space may result in asphyxiation. The symptoms of asphyxia depend on the rapidity with which the oxygen deficiency develops and how long it continues. In sudden acute asphyxia, unconsciousness may be immediate. With slow development, there may

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.
