Question 215Safety & Environmental - QMED70% to pass
When a ship's low-pressure CO2 fixed fire extinguishing system is activated from a remote location, what determines the quantity of CO2 that will be released into the selected compartment?
AI Explanation
The correct answer is C) A timer mechanism controls the discharge valve and is preset for the space being activated.
The quantity of CO2 released into a protected space by a low-pressure CO2 fixed fire extinguishing system is determined by a preset timer mechanism. This timer is designed to discharge the proper amount of CO2 required to extinguish a fire in the specific protected space. The timer controls the opening and closing of the CO2 discharge valve, ensuring the appropriate quantity of CO2 is released based on the volume of the protected compartment. The other answer choices are incorrect because they do not accurately describe how the CO2 discharge is controlled in these systems.
