What are asphyxiants?

Asphyxiants are substances that displace oxygen or interfere with its use in the body, leading to a lack of oxygen supply to vital organs and tissues. When there is an insufficient oxygen level in the air, or if asphyxiants like carbon dioxide or nitrogen are present in high concentrations, the body's ability to function normally is compromised. This can result in symptoms ranging from confusion and dizziness to unconsciousness or even death if exposure is prolonged.

Understanding the nature of asphyxiants is crucial for safety in environments where these gases might be present, such as confined spaces or industrial settings. Knowing that they can displace oxygen helps workers recognize the need for ventilation and monitoring of air quality to prevent serious health risks. Other options mention irritation, enhanced breathing, and fire safety; however, they do not accurately describe the primary function of asphyxiants, which specifically relates to oxygen displacement and its effects on the body.
