Question 293Safety & Environmental - Assistant Engineer

The correct answer is B) over pressurization of the CO2 discharge piping. A safety outlet is provided on the CO2 discharge piping to prevent over pressurization of the piping system. This is necessary because the rapid discharge of CO2 can cause a dangerous increase in pressure within the piping. The safety outlet allows excess pressure to be safely released, preventing the piping from rupturing. The other options are incorrect because they do not directly address the purpose of the safety outlet on the CO2 discharge piping. Option A is incorrect as the safety outlet is not intended to prevent rupture of the CO2 cylinder itself. Options C and D are also incorrect, as the safety outlet is specifically designed to protect the piping system, not the spaces being flooded or the presence of personnel.
