Q. Why should you wear a self-contained breathing apparatus before entering the engine room after the fixed CO2 system has been discharged to combat a major fire?

A. Because carbon dioxide dilutes the oxygen concentration in the atmosphere and may cause asphyxiation.
B. Because carbon dioxide breaks down in a fire into carbon monoxide which may cause blood poisoning in the person breathing this gas.
C. Because carbon dioxide is a colorless and odorless gas that becomes highly toxic in the presence of high temperatures and will quickly incapacitate a person exposed to this gas.
D. This action is unnecessary as carbon dioxide is not poisonous nor toxic but is a relatively harmless gas.
