Question 237Safety & Environmental - 1st Asst/Chief

The correct answer is A) The master cylinder sends gas to the actuators on all bottles in the affected banks. This is the correct answer because high-pressure CO2 fire suppression systems in engine rooms are designed to release all the bottles in the affected bank(s) simultaneously when the system is activated. The master cylinder is the central component that triggers the release of CO2 gas from all the bottles connected to it, rather than releasing the bottles individually or automatically. The other options are incorrect because: B) Bottles are not released individually, C) The pull wire does not release all bottles, and D) The smoke detection system does not automatically release the CO2 - the system must be manually activated.
