Question 937 Deck General

The correct answer is B) 2 locations. According to the US Coast Guard regulations, remote controls for quick-closing shut off valves are required in two locations: 1) at the main control station, and 2) at the valve itself. This redundancy ensures that the valves can be closed quickly in an emergency from both the main control station and the local valve location. The other answer choices are incorrect because they do not accurately reflect the regulatory requirement for two remote control locations.
