Simple asphyxiant gases
Did you know?
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). Because asphyxiant gases are relatively inert and odorless, their … Visa mer Asphyxiant gases in the breathing air are normally not hazardous. Only where elevated concentrations of asphyxiant gases displace the normal oxygen concentration does a hazard exist. Examples are: Visa mer • Inert gas asphyxiation • Limnic eruption • Mining accidents Visa mer The risk of breathing asphyxiant gases is frequently underestimated leading to fatalities, typically from breathing helium in domestic … Visa mer The dangers of excess concentrations of nontoxic gases has been recognized for centuries within the mining industry.
