When oxygen levels exceed 23.5%, the atmosphere is classified as oxygen enriched. This classification is crucial in both occupational safety and emergency response situations, as elevated oxygen levels can significantly increase the risk of fire and explosion. In environments where the oxygen concentration is higher than normal air (which contains approximately 21% oxygen), materials that may not typically ignite can become flammable, leading to hazardous conditions for personnel.

Understanding the distinction of oxygen enriched environments is essential for safety protocols, particularly in settings that involve flammable materials or activities like rescue operations, where additional precautions need to be taken. Knowing how to identify and respond to oxygen enriched conditions can help prevent accidents and ensure the safety of rescue teams and victims alike.
