Question 173Safety & Environmental - QMED
70% to passWhich of the gases listed is the poisonous gas most likely to be found in a closed compartment involved in a fire?
ANitrogen
BHydrogen
CCarbon monoxide
DCarbon dioxide
AI Explanation
The correct answer is C) Carbon monoxide. Carbon monoxide is the poisonous gas most likely to be found in a closed compartment involved in a fire. This is because carbon monoxide is a colorless, odorless gas that is a byproduct of incomplete combustion, which often occurs in fires. In a closed compartment, carbon monoxide can quickly build up to dangerous levels and pose a serious threat to human health and safety. The other options are incorrect because nitrogen and hydrogen are not toxic gases, and carbon dioxide, while potentially dangerous in high concentrations, is not as acutely poisonous as carbon monoxide.
