What would be a major consequence of allowing the refrigeration system of a low-pressure fixed CO2 fire extinguishing system to remain inoperable?
The entire charge may eventually be lost due to CO2 boil-off venting through the relief valve.
Liquid CO2 would overflow from the tank through the drain line as the temperature is increased.
Excessive condensation inside the tank would freeze causing a restriction in the discharge piping.
The warmed charge of CO2 would not be effective in extinguishing a fire.
