Question 53 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is B **Why Option B ("2") is correct:** Regulations (such as those governing marine safety, industrial piping, or boiler systems, often dictated by bodies like the US Coast Guard, ABS, or specific industry standards) typically require that remote controls for quick-closing shut off valves (often associated with fuel oil service systems) be accessible from at least two widely separated locations. This is a critical safety measure designed to ensure that the fuel supply can be rapidly stopped in case of an emergency (like a fire or major leak), even if access to one control station is compromised or blocked. The two required locations generally include: 1. **A location within the machinery space or near the equipment itself** (for local operation and routine shutdowns). 2. **A remote location outside of the machinery space** (usually in an accessible control room, fire station, or deck area) to allow shutdown if the machinery space is inaccessible due to fire or smoke. **Why the other options are incorrect:** * **A) 1:** Requiring only one location is insufficient for safety. If that single location is compromised (e.g., covered in fire or smoke), the crew cannot remotely secure the fuel source, leading to a potentially catastrophic situation. * **C) 3:** While having three locations (e.g., local, main remote, and bridge/secondary remote) might offer enhanced safety, the minimum regulatory requirement across most major codes is typically two, making "3" an excessive minimum requirement unless specifically mandated by a niche standard. * **D) 4:** Requiring four locations is far beyond the standard minimum regulatory requirement for basic fuel oil service systems. While more controls could be installed voluntarily, four is not the required minimum number.
