According to the T-Boat regulations the reason for providing adequate ventilation for a battery storage area is to prevent __________.

Correct Answer: Option B — accumulation of explosive and toxic gases the battery can generate

Lead-acid batteries emit hydrogen gas during charging, which is highly explosive when mixed with air. 46 CFR regulations mandate adequate ventilation in battery storage areas to prevent the accumulation of these gases, mitigating the risk of fire or explosion within the vessel's enclosed spaces.
