To prevent damage by and to storage batteries aboard small passenger vessels they should be located __________.

Correct Answer: Option D — All of the above

46 CFR 183.320 mandates that storage batteries be secured to prevent movement, placed in acid-resistant trays to contain electrolyte spills, and located in a well-ventilated area to dissipate hydrogen gas. These measures collectively prevent structural damage, electrical shorts, and the accumulation of explosive gases within the vessel.
