Question 4
QMED04After taking on fuel oil, the hoses should be disconnected and _________.
AI Explanation
The Correct Answer is B
**Why Option B ("drained into buckets or fuel tanks") is correct:**
After transferring fuel oil, the hoses contain residual fuel. This fuel is a pollutant and often a valuable resource (though small in quantity). Best practice requires the residual fuel to be collected and contained. Draining the hoses into a designated **bucket** (often called a drip pan or catch basin) or back into the **fuel tank** is the proper procedure. This prevents pollution, maintains a clean deck/work area, and adheres to environmental regulations (like MARPOL and local laws) which strictly prohibit the discharge of oil.
**Why the other options are incorrect:**
* **A) draped over the fantail to dry out:** This is incorrect and dangerous. Residual fuel will drip onto the deck, creating a slipping hazard, staining the vessel, and potentially leading to discharge overboard (especially if the fantail is washed down or subject to splash). Hoses are usually coiled or stored, not simply draped.
* **C) drained into the bilges and washed out:** This is strictly prohibited. The bilge is the lowest internal space of the hull. Allowing fuel oil into the bilges contaminates the bilge water, making subsequent pumping of that water illegal without expensive treatment (as oil-water separators cannot effectively handle large, concentrated quantities of fuel oil). This action directly causes environmental pollution and regulatory violations.
* **D) drained over the side and washed out:** This is a major environmental violation and is illegal under virtually all maritime laws (including MARPOL and national environmental acts). Discharging any petroleum product (even residual hose drainage) directly into the water is considered pollution.
