Blackdamp (also known as stythe or choke damp) is an asphyxiant, reducing the available oxygen content of air to a level incapable of sustaining human or animal life. It is not a single gas but a mixture of unbreathable gasses left after oxygen is removed from the air and typically consists of nitrogen, argon, carbon dioxide and water vapour. The suffix damp is believed to derive from the German word for vapours ("Dampf"). The word damp is used in similar mining terms such as white damp (carbon monoxide), fire damp (typically methane) and stink damp (hydrogen sulfide).
