70% to pass

Spaces containing batteries require good ventilation because _______________.

A ventilation avoids flammable gas accumulation
B ventilation supplies extra oxygen for the battery
C less water would be used
D ventilation avoids CO2 buildup
AI Explanation

The correct answer is A) ventilation avoids flammable gas accumulation. Spaces containing batteries require good ventilation because the batteries can produce hydrogen gas, which is highly flammable. Proper ventilation helps to disperse this gas and prevent it from accumulating to dangerous levels. This is a key safety requirement specified in regulations for the design and operation of battery compartments on vessels. The other answer choices are incorrect. Option B is wrong because ventilation is not primarily to supply extra oxygen, but to remove hydrogen. Option C is incorrect because water usage is not the main concern. Option D is wrong because the issue is flammable gas accumulation, not CO2 buildup.
