Question 27 TK02 - Tank Vessel Assistant - Liquefied Gas

The Correct Answer is B. **Why Option B ("Cargo-holds") is correct:** 46 CFR (Code of Federal Regulations, specific to the U.S. Coast Guard regulations governing vessels) contains stipulations regarding the safety and arrangement of fuel oil tanks. While the general rule is to locate sounding tubes and access openings for fuel oil tanks in areas readily accessible for measurement and inspection (like machinery spaces, pump rooms, or protected decks), there are specific, limited exceptions detailed in regulations such as 46 CFR § 32.55-25 (related to tank vent pipes, which often share similar location constraints) or general arrangement standards. Crucially, the regulations often prohibit placing openings for fuel oil tanks in accommodations or service spaces where potential spills or vapors would pose a direct hazard to personnel (A, C, and D). However, **cargo-holds** (Option B), particularly those not used for storing bulk flammable liquids or highly volatile materials, are sometimes acceptable locations for access to sounding tubes or manholes, provided the connection is made through a robust, sealed enclosure or a cofferdam, and the access is suitably protected and sealed to prevent cargo contamination or ignition of the tank contents. Furthermore, some interpretation and past practice under USCG regulations have permitted access through compartments deemed low-risk compared to the occupied spaces listed in A, C, and D. In the context of restrictive safety regulations aimed at protecting crew and passengers, the cargo hold is the least hazardous of the provided non-machinery space options. **Why the other options are incorrect:** * **A) Crew lounge:** This is an accommodation space. 46 CFR generally prohibits placing fuel oil tank openings, including sounding tubes and access covers, in accommodations, control stations, or service spaces, to prevent the escape of flammable vapors and protect personnel from spills (46 CFR § 32.55-15 and similar provisions related to safety). * **C) Laundries:** This is a service space. Similar to the crew lounge, laundries are areas where crew members are present, and the opening of a sounding tube or access would introduce an unacceptable risk of fire, explosion, or vapor inhalation. * **D) Washrooms:** This is a sanitary/service space. Locating fuel oil access in washrooms is strictly prohibited due to the risk of exposure to personnel and contamination, falling under the same general prohibitions as accommodation and service spaces.
