An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation (suffocation).
Asphyxiant gas – Nontoxic or minimally toxic gas which can displace oxygen in breathing air; Erotic asphyxiation – Intentional restriction of oxygen to the brain for sexual arousal; Hypercapnia – Abnormally high tissue carbon dioxide levels; Respiratory acidosis – Decrease in blood pH due to insufficient breathing
Blackdamp (also known as stythe or choke damp), sometimes found in enclosed environments such as mines, sewers, wells, tunnels and ships' holds, is an asphyxiant, reducing the available oxygen content of air to a level incapable of sustaining human or animal life.
A gas chamber is an apparatus for killing humans or other animals with gas, consisting of a sealed chamber into which a poisonous or asphyxiant gas is introduced. Poisonous agents used include hydrogen cyanide and carbon monoxide .
are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere; or; are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does; or; do not come under the other divisions.

It also uses the broader term "impair", rather than "prevent", with respect to the ability to escape. For example, blinding but non-toxic smoke could be considered IDLH under the OSHA definition if it would impair the ability to escape a "dangerous" but not life-threatening atmosphere (such as tear gas).
Gas leaks can also release carbon monoxide, another dangerous gas that can affect your health. Symptoms of carbon monoxide poisoning include: Tiredness. Nausea and dizziness. Headache. Chest or ...
