70% to passWhen re-entering an engine room that has been flooded with CO2, the investigating team should initially _______________.
Aattempt to operate propulsion machinery
Benter from the lowest possible level
Cleave the access door partially open
Denter from the highest level with breathing apparatus
AI Explanation
The correct answer is D) enter from the highest level with breathing apparatus. When re-entering an engine room that has been flooded with CO2, the investigating team should initially enter from the highest level while wearing breathing apparatus. This is because CO2 is heavier than air, so it will accumulate at the lower levels of the engine room. Entering from the highest level with breathing apparatus ensures the team can safely assess the situation and take appropriate actions without being exposed to the hazardous CO2 gas. The other options are incorrect because they do not properly address the risk of the CO2 gas accumulation.
