Question 772 Deck Safety

The correct answer is B) 2 pilot cylinders. When a fixed fire extinguishing system uses pilot cylinder pressure to release the CO2 from the storage cylinders, the regulations require that there be at least two pilot cylinders. This redundancy ensures that the system can still function properly if one of the pilot cylinders fails or malfunctions. The other options are incorrect because: A) 1 pilot cylinder would not provide the necessary redundancy, C) 3 pilot cylinders are not the minimum required, and D) 4 pilot cylinders exceed the minimum requirement.
