46 CFR directs the location of fuel oil sounding tubes and access openings for fuel oil tanks on cargo vessels. Where can the tubes be located?

Correct Answer: Option A — Cargo holds

46 CFR regulations permit fuel oil sounding tubes and access openings to be located in cargo holds, provided they are properly protected and fitted with secure, gastight closures. This arrangement ensures that fuel tanks remain accessible for gauging while maintaining the integrity of the vessel's subdivision and fire safety.
