What does asphyxiant refer to?

Asphyxiant refers to a substance that can cause suffocation by displacing oxygen in the air. When an asphyxiant gas or vapor is present, it can replace the oxygen that is essential for human respiration, leading to a lack of oxygen in the environment. This is particularly dangerous in confined spaces where oxygen levels can drop swiftly. Common examples of asphyxiants include carbon dioxide, nitrogen, and various chemical vapors that are heavier than air. Understanding the role of asphyxiants is crucial for ensuring safety in environments where such substances might be present, emphasizing the importance of proper ventilation and monitoring air quality to prevent health risks associated with oxygen deprivation.
