Question 771 Deck Safety

The correct answer is A) 2. According to the regulations governing fixed CO2 fire extinguishing systems, the number of required pilot cylinders must be at least 2. This is to ensure that there is a redundant system in place to release the CO2 from the main bank of cylinders in the event of a fire. Having at least 2 pilot cylinders provides a backup in case one of the pilot cylinders fails to function properly. The other answer choices (B, C, and D) are incorrect because they specify a higher number of pilot cylinders than the minimum requirement of 2.
