What term is used to describe substances that can cause asphyxiation?

The term used to describe substances that can cause asphyxiation is "asphyxiants." These substances can displace oxygen in the environment, leading to a reduction of breathable air, which may result in suffocation or asphyxiation. Understanding asphyxiants is crucial in safety protocols, especially in environments where there is a risk of exposure to such gases or vapors that can prevent adequate oxygen supply to the body.

In contrast, stimulants are substances that enhance bodily functions—like increasing alertness or energy—rather than causing harm through lack of oxygen. Allergens are substances that can cause allergic reactions in sensitive individuals, while toxins typically refer to harmful substances that can cause disease or injury through chemical means rather than specifically affecting oxygen levels in the air. Thus, recognizing the unique nature of asphyxiants is essential for maintaining health and safety in potentially hazardous conditions.
