Question

A man working in a furnace room suffered from asphyxiation. What should be the main reason?

• A. More O\textsubscript{2} level in the furnace room
• B. CO poisoning due to high CO level in the furnace room
• C. More O\textsubscript{2} as well as fumes in the furnace room
• D. Less O\textsubscript{2} level in the furnace room

Hint:

Carbon monoxide has much higher affinity for haemoglobin than oxygen.

Answer 1

The Correct Option is B

Step 1: Understanding asphyxiation.
Asphyxiation occurs when oxygen supply to body tissues is blocked or reduced.

Step 2: Role of carbon monoxide.
Carbon monoxide binds strongly with haemoglobin to form carboxyhaemoglobin, preventing oxygen transport in blood.

Step 3: Furnace room condition.
Incomplete combustion in furnace rooms produces high levels of carbon monoxide, leading to poisoning.

Step 4: Conclusion.
Thus, the main reason for asphyxiation is carbon monoxide poisoning.
