70% to pass

The CO2 flooding system is actuated by a sequence of steps which are _______________.

A sound evacuation alarm, pull handle
B open stop valve, open control valve, trip alarm
C break glass, pull valve, break glass, pull cylinder control
D open bypass valve, break glass, pull handle
AI Explanation

The correct answer is C) break glass, pull valve, break glass, pull cylinder control. This sequence of steps is typical for actuating a CO2 flooding system, which is a common fire suppression system used on ships and in other marine environments. The key steps involve breaking a glass cover to access the pull valve, then pulling the cylinder control to release the CO2 into the protected space. This multi-step process helps prevent accidental discharge of the system. The other answer choices do not accurately reflect the standard procedure for activating a CO2 flooding system. For example, option A does not involve breaking the glass or pulling the cylinder control, while options B and D do not include the necessary steps of breaking the glass and pulling the valve.
