Asphyxiant gases are gases that displace oxygen in the air and can cause death if inhaled in high concentrations. They are toxic because they can reduce the oxygen content of the surrounding air to a dangerous level. Asphyxiants are not considered poisonous, as they do not directly cause harm to the body. However, when inhaled in large concentrations, they can cause asphyxiation, which is a form of suffocation.
Types of Asphyxiants
There are several types of asphyxiants, including carbon dioxide, nitrogen, argon, and helium. Carbon dioxide is the most common type of asphyxiant and is found in many everyday products such as refrigerants, fire extinguishers, and air conditioners. Nitrogen is another type of asphyxiant and is found naturally in the air. Argon and helium are both also found in the air, but in much lower concentrations than nitrogen or carbon dioxide.
Effects of Asphyxiants
When inhaled in high concentrations, asphyxiants can cause hypoxia or asphyxiation, which is a condition in which the body does not get enough oxygen. Symptoms of hypoxia include dizziness, confusion, and loss of consciousness. In extreme cases, it can lead to death. Asphyxiants can also cause irritation to the eyes, nose, and throat, as well as headaches, nausea, and vomiting.
Toxicity of Asphyxiants
Asphyxiants are not considered poisonous, as they do not directly cause harm to the body. However, when inhaled in large concentrations, they can cause asphyxiation, which is a form of suffocation. Asphyxiants can also irritate the eyes, nose, and throat, as well as cause headaches, nausea, and vomiting. As a result, they are considered hazardous and should be handled with caution.
