Which of the following is considered a respiratory hazard present in an IDLH atmosphere?

• A. Pure oxygen
• B. Elevated temperatures
• C. Fresh air
• D. Normal atmospheric pressure

Answer: (B)

An Immediately Dangerous to Life or Health (IDLH) atmosphere is one that poses a serious risk to life or health. Elevated temperatures are indeed considered a respiratory hazard in such scenarios because they can lead to heat stress or thermal inhalation injuries. When air is excessively hot, inhaling it can impair respiratory function and overall physiological performance, potentially resulting in a life-threatening situation. In contrast, pure oxygen, fresh air, and normal atmospheric pressure do not pose a respiratory hazard. While pure oxygen can be beneficial in certain medical situations, it can be dangerous in high concentrations due to the risk of fire and oxygen toxicity. Fresh air is vital for maintaining life and does not present a respiratory threat. Normal atmospheric pressure is part of what constitutes a safe and breathable environment, thus making it non-hazardous in an IDLH context.
