Deck General USCG Question #994 (Set 31)

Which statement is FALSE concerning precautions during fueling operations?

Official USCG Answer & Rule Citation

Correct Answer: Option A — Fuel tanks should be topped off with no room for expansion.

Liquid cargo and bunkers expand significantly with temperature increases. Topping off tanks completely leaves no room for thermal expansion, creating dangerous overpressurization risks that can rupture tanks or spill fuel. Standard safety protocols require maintaining a specific percentage of ullage or expansion space.
