Asphyxiant:
Definition and Types of Asphyxiants
An asphyxiant is any substance or environmental condition that prevents or significantly impairs the body's ability to take in adequate oxygen. The most common asphyxiants are carbon dioxide, nitrogen, and carbon monoxide.
Carbon dioxide is a colorless and odorless gas that is a product of respiration. It is the most common asphyxiant, and can be found in confined places like cars, ships, and small rooms. High concentrations of carbon dioxide can cause dizziness, headaches, and nausea.
Nitrogen is a colorless and odorless gas that is necessary for plants and animals to survive. Nitrogen is found in the air, but in small concentrations. It can become an asphyxiant when it is concentrated in an enclosed area or in a confined space.
Carbon monoxide is a colorless and odorless gas that is produced by burning fuel. It is the most dangerous asphyxiant, as it can be fatal in even small concentrations. Carbon monoxide can be found in places like car engines, boats, and furnaces. Inhaling high concentrations of carbon monoxide can cause dizziness, headaches, and nausea.
Prevention and Treatment of Asphyxiation
The best way to prevent asphyxiation is to avoid confined spaces and to make sure that proper ventilation is available in any enclosed area. It is also important to be aware of the potential for asphyxiation in any environment where combustible fuels are used, such as car engines and furnaces.
If someone is suffering from asphyxiation, it is important to get them to a safe area and to administer oxygen if possible. If breathing has stopped, CPR should be administered and emergency medical services should be called immediately.
