Classification of Asphyxiants
Asphyxiants are gases and vapors that can cause oxygen deprivation in a person’s body. Asphyxiants can come from many sources, including natural and industrial sources. The classification of asphyxiants depends on the type of gas or vapor, the concentration of the gas, and the environment in which it is released.
Inert Asphyxiants
Inert asphyxiants are gases or vapors that displace oxygen in the air. Examples of inert asphyxiants include nitrogen, helium, argon and carbon dioxide. These gases can be found in natural environments, such as underground caves, or can be produced in industrial settings. Inert asphyxiants can be deadly when inhaled in high concentrations.
Irritant Asphyxiants
Irritant asphyxiants are gases or vapors that irritate the respiratory system, resulting in difficulty breathing and ultimately asphyxiation. Examples of irritant asphyxiants include ammonia, chlorine, and sulfur dioxide. These gases can be found in natural environments, such as volcanoes or hot springs, or can be produced in industrial settings. Irritant asphyxiants can be deadly when inhaled in high concentrations.
Toxic Asphyxiants
Toxic asphyxiants are gases or vapors that are poisonous. Examples of toxic asphyxiants include carbon monoxide, hydrogen sulfide, and ozone. These gases can be found in natural environments, such as marshlands or oil wells, or can be produced in industrial settings. Toxic asphyxiants can be deadly when inhaled in high concentrations.
