Question 60 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is D **Explanation for D (Correct Answer):** Standard maritime safety regulations (often reflected in SOLAS or national/flag state interpretations) require fire hoses and nozzles to be readily connected to hydrants so they can be immediately brought into use during a fire. However, an exception is often made during cargo operations. If a fire hose, when connected to the hydrant, would obstruct or be at risk of being damaged by ongoing cargo loading or discharging activities, the regulation allows the hose to be temporarily disconnected and stored nearby, provided it can be immediately remade ready for use. **Explanation of Incorrect Options:** * **A) vessel is in port:** The requirement to have hoses connected is generally stricter when the vessel is in port, especially during cargo operations or bunkering, as the risks are higher. Being in port is not a reason for exemption; it's a time when vigilance is maximized. * **B) fire main system is not charged:** The requirement to have the hose connected is independent of whether the fire main is currently pressurized ("charged"). If a fire breaks out, the pumps will be started, and the fire main will be charged instantly; the hose must be ready to use immediately upon pressurization. * **C) fire pumps are used for purposes other than supplying water to the fire main:** While fire pumps can occasionally be used for bilge or ballast operations (in some non-emergency scenarios), this operational state does not negate the fundamental requirement to maintain fire-fighting readiness, which includes having hoses connected and ready for immediate deployment. If a fire starts, the pumps must be instantly switched back to the fire main.
