The statement that asphyxiants prevent oxygen from combining in sufficient quantities with the blood is accurate. Asphyxiants are substances that can interfere with the body's ability to extract or absorb oxygen, leading to a reduced amount of oxygen available in the bloodstream. This can occur through various mechanisms, such as displacing oxygen in the air or binding to hemoglobin more effectively than oxygen, which inhibits oxygen transport.

Understanding the nature of asphyxiants is crucial for HAZMAT responders. Many asphyxiants, such as carbon monoxide or nitrogen gas, can create life-threatening situations because they reduce the oxygen levels that the body needs to function properly. Awareness of this effect helps in assessing risk and implementing appropriate safety measures during hazardous materials incidents.
