The specific guidelines for prevention of asphyxiation due to displacement of oxygen by asphyxiant gases is covered under CGA's pamphlet SB-2, Oxygen-Deficient Atmospheres. [15] Specific guidelines for use of gases other than air in back-up respirators is covered in pamphlet SB-28, Safety of Instrument Air Systems Backed Up by Gases Other Than Air.
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
Sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. [53] Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.
Boiling liquid oxygen. This is a list of gases at standard conditions, which means substances that boil or sublime at or below 25 °C (77 °F) ...
Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents (argon has the European food additive code E938). Aerial oxidation, hydrolysis, and other chemical reactions that degrade the products are retarded or prevented entirely.
If the concentration of exposure is excessively high, the gas may displace oxygen resulting in fatal asphyxiation. [41] Generally, patients and workers should be educated by medical personnel on how to identify the signs and symptoms of Nitrogen dioxide poisoning.
The administration is trying to ramp up hydrogen production to displace fossil fuels as an energy source for sectors of the economy that emit massive greenhouse gases, yet are difficult to ...
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
