Question 3691 Deck General

The correct answer is B) the CO2 cylinders are also in the space. According to Coast Guard regulations, control valves for a CO2 fire extinguishing system may be located within the protected space if the CO2 cylinders are also located in the same space. This is allowed because the control valves need to be close to the CO2 cylinders in order to effectively control the release of the CO2 into the protected space. The other answer choices are incorrect because A) an automatic heat-sensing trip is not required for the control valves to be located inside the protected space, C) it is not necessarily impractical to locate them outside, and D) having a control valve outside is not a requirement for locating the other control valves inside the protected space.
