Question 775Deck Safety70% to pass
A crew member reports that the high-pressure alarm light of a low-pressure CO2 fixed fire extinguishing system is illuminated. The most probable cause of this condition would be that _______________.
AI Explanation
The correct answer is A) the tank cooling system has malfunctioned.
The high-pressure alarm light being illuminated on a low-pressure CO2 fixed fire extinguishing system indicates that the pressure in the CO2 tank is too high, which is typically caused by the tank cooling system malfunctioning. The tank cooling system is designed to keep the CO2 tank at the proper temperature to maintain the desired pressure, and if this system fails, the pressure in the tank will rise, triggering the high-pressure alarm.
The other answer choices are incorrect because they do not directly explain the high-pressure condition that would cause the alarm light to be illuminated. Excessive insulation (B), a leaking pilot cylinder discharge valve (C), or an air leak in the tank (D) would not necessarily result in a high-pressure situation in the CO2 system.
