Question 235Safety & Environmental - 1st Asst/Chief70% to pass
Actuating the fixed CO2 system should cause the automatic shutdown of the _______________.
AI Explanation
The correct answer is D) supply and exhaust ventilation.
When the fixed CO2 fire extinguishing system is activated, it will automatically shut down both the supply and exhaust ventilation systems. This is a critical safety feature to prevent the CO2 from being drawn out of the protected space, which would reduce the effectiveness of the fire suppression. The regulations require this automatic shutdown of both the supply and exhaust ventilation to maintain the proper CO2 concentration in the protected space.
The other options are incorrect because shutting down only the fuel supply or only the exhaust ventilation would not fully contain the CO2 within the space, compromising the fire suppression system.
