70% to passWhen fighting a machinery space fire, you should operate a fixed CO2 system by opening the control valve to the space protected and _______________.
Avisually checking to see that CO2 is discharging through the piping
Boperating a separate control to release CO2
Cmodulating the proper amount of CO2 from individual bottles
Dlistening for the sound of the warning siren
AI Explanation
The correct answer is B) operating a separate control to release CO2. When fighting a machinery space fire, the proper procedure for operating a fixed CO2 system is to first open the control valve to the space protected, and then operate a separate control, typically a remote release station, to actually discharge the CO2 into the space. This separate control ensures the CO2 is only released when the operator is ready and all personnel have evacuated the area. The other options are incorrect because they do not accurately describe the proper two-step process required to activate a fixed CO2 system.
