Question 61 RVR05 - Master of LT 100 GRT

The Correct Answer is B **Explanation for Option B (Correct Answer):** Option B, "Locate potable (drinking) water tanks as low as possible in the bilge," represents a poor sanitary procedure. The bilge is the lowest part of a vessel, where water, oil, fuel, sewage residue, dirt, and various contaminants accumulate. Placing a drinking water tank directly in this inherently dirty area significantly increases the risk of contamination (e.g., through leaks, condensation, or compromised fittings), making it a major sanitary hazard. **Explanation for Incorrect Options:** * **A) Keep and use a separate filling hose for potable (drinking) water:** This is a **good** sanitary procedure. Using a dedicated hose prevents cross-contamination that would occur if the same hose were used for non-potable water, chemicals, or fuel. * **C) Eliminate enclosed spaces in which trash, food particles, dirt may gather:** This is a **good** sanitary procedure. Eliminating hidden spaces prevents the accumulation and decay of organic matter, which can harbor pests and bacteria. * **D) After washing dishes with soap and warm water, sterilize them in water of at least 170°F (76.7°C):** This is a **good** sanitary procedure. Washing removes visible debris, and following it up with high-temperature sanitization (sterilization) kills remaining pathogens, ensuring the dishes are safe for reuse.
