Question 1417Deck General70% to pass
Asphyxia is generally limited to enclosed spaces, and the deficiency of breathable air in an enclosed space can occur with any of the following conditions. Indicate the condition that will NOT cause asphyxia.
AI Explanation
The correct answer is A) When 21% of oxygen is present.
Asphyxia is generally caused by a deficiency of breathable air, specifically a lack of oxygen. Normal atmospheric air contains approximately 21% oxygen. As long as the oxygen concentration remains at 21%, asphyxia will not occur, even in an enclosed space. The other conditions listed, such as the presence of inert gases, cargo vapors, or rusting surfaces, can displace or consume oxygen, leading to an asphyxiating atmosphere. Therefore, option A is the correct answer, as 21% oxygen is sufficient to prevent asphyxia.
