Question 560Deck Safety70% to pass

Which statement is TRUE concerning a fire in a machinery space?

AI Explanation
The correct answer is D) the fixed carbon dioxide system should be used only when all other means of extinguishment have failed. The reason this is the correct answer is that carbon dioxide systems are hazardous to personnel and should only be used as a last resort in machinery spaces. The regulations require attempting other extinguishing methods, such as portable fire extinguishers or water, before activating the fixed CO2 system, as CO2 can displace oxygen and pose a serious risk to crew members in the space. The other options are incorrect because they either recommend unsafe actions (A, B) or contradict the proper protocol for using the CO2 system (C).
